DON'T Buy A Motorcycle Battery Before You Watch This

Today we'll cover the seven things that determine the lifespan of your motorcycle battery, and how to maximize it. Four of these battery lifespan influences are completely in your control, and it's important to be aware of the other three factors before buying a new battery.
We'll look at why the initial setup and charge of a new battery is crucial for its performance and longevity. We'll also cover how your motorcycle riding habits can impact your battery's lifespan, and the importance of good maintenance and storage.
We'll look at the impact of battery capacity, type, and manufacturer choice. I'll explain why I recommend high-quality brands like Yuasa and Antigravity can produce the best motorcycle battery, and caution people against buying from shady Amazon and eBay sellers that prioritize profits over quality.
Overall, this video is a comprehensive guide to maximizing your motorcycle battery's lifespan.

and like Ex Girlfriends, lithium batteries might burn your house down. Stick with the standard issue.

[@YouMotorcycle]

Lmao thanks man!

[@joesmith1544]

LifePo4 batteries are very safe. I still have an old one sitting in the house for 10 years. They are iron phosphate, a stable chemical. Lithium ion are the dangerous ones. I own both. I keep the lithium ion e-bike battery outside at all times except when charging after a ride.

We just had a lithium ebike battery burn down a house a few blocks away. It seems like a foreign concept until it happens somewhere you've driven past a million times. Though to be honest it was probably the charger to blame not the battery itself

[@mikew3462]

I bought a brand new battery before one winter. I let the bike sit for 6+ months without taking care of the battery, by the end of the winter the battery was dead! Save your money, pull your battery and treat it right! Thanks for the video! 👍🏼👍🏼👍🏼

[@YouMotorcycle]

Thanks Mike, sorry you had to learn that one the hard way!

[@David-xl9cp]

I worked in motorcycle shop in the 70’s and the best battery, which is still the same to day is Yuasa batteries and if you plug them in to a battery conditioner ALL THE TIME, it will last years (up to 10 years is not uncommon) as these recycle the battery charge and keeping it warm, especially in the winter. OptiMate 3 (or 4) Motorcycle Battery Charger & Tester is worth every penny for doing this job. I’ve got the small cigarette style socket on my Triumph so this is a very fast way to plug in when you get home, it takes seconds.

[@YouMotorcycle]

We call them battery tender pigtails here and yep, being able to quickly plug in the bike in two seconds is great!

[@bliblablubb0712]

I used Yuasa in my small honda scooter. I did nothing for 5 years and 3 more years I charged it once a month in winter season. I sold my bike and the battery is still good to go. Very good brand indeed.

[@ensidfkgnur]

Replaced my 2013 Gold Wing Yuasa with same model Yuasa just out of caution before a trip. Put the old one in my 1965 Cub Cadet lawn tractor. Both batteries still start strong. The old one is probably 12 yrs old now! Never tendered, always garaged. I used to get cheap Walmart batteries for the Cub Cadet and would be lucky to get 2 good years then have to use a tender. The Yuasa in the lawn tractor is physically smaller than the intended size so I block it off to keep it from rattling around. No parasitic drain in either application. No complaints!

[@YouMotorcycle]

They're little tanks. I'm surprised you're getting that kind of life without that putting it on a maintainer though!

[@ensidfkgnur]

@@YouMotorcycle I THOUGHT about it but wanted to see what would happen if I just kept the same routine. Selling the Gold Wing and focusing on small bikes so not sure what to do when this one eventually gives out. The Cub has an 8hp Kohler so not a huge load to start.

[@johnanderson9735]

So many people, myself included leave batteries connected to battery tenders when the vehicle is not in use, with no issues whatsoever. Many years ago we had electric forklifts at work. The maintenance crew would check the acid in the cells and test the charge levels meticulously. A lot of those vehicles never had failed batteries because of great battery maintenance!

Yup! Take care of stuff with quality equipment and it will last!

I agree, when I'm not riding the bike it's on the charger! Battery lasts 7 yo 8 years. I even do the same with my lithium battery! Most people are just lazy and don't charge then wonder why battery is dead on 2 years.

[@YouMotorcycle]

Very cool to see that you're doing the same thing and getting good life out of your batteries as well! Let's be fair, a lot of people are definitely lazy, some don't know any better, and for many, they just might not have the option to plug in easily after every ride. For years I used to have to leave my bike parked outdoors, then I got a condo and I could park indoors but there was no charger by my parking spot, etc. But still, I would bring my battery out of the bike and into the condo every winter to keep it on a charger in my closet. I see a lot of riders not doing that over the winters here.

My yuasa battery kind a bulging on its sides. Do I need to replace it? Im getting 12.5 v on it and it's 5 years old.

[@YouMotorcycle]

Great question. I've seen that on GoPro batteries a lot, haven't personally seen it on motorcycle batteries. From what I understand it could be due to overcharging, excessive heat, or internal battery issues. If you're not hard up for cash, and you've already gotten five years out of this one, it might be worth replacing it for peace of mind.... BUT.... what I would do before replacing it is make sure you test your charging system. Make sure everything on your motorcycle is okay. You don't want to spend money on a new battery, just to end up ruining it because there was a charging system problem on your bike, and then you end up having to buy a third battery. That would suck. Hope this helps! Let me know how it all works out!

[@jamesgenodia]

@@YouMotorcycle my charging system is fine. I only have 13.6 v max when i revved the throttle. I only noticed it after charging my battery using my friends charger that he used on his lithium ion battery, could that be it? I mean i only charged it for no more than 20 mins.

[@YouMotorcycle]

@@jamesgenodia is his battery charger a lithium-only battery charger? If so, maybe🤔. Some have switches to go between lithium mode and lead acid or gel, but others are lithium only.

[@jamesgenodia]

@@YouMotorcycle yes when i read the label it was for lithium battery. I thought that it would be fine for lead acid type battery. Anyway i tested the old yuasa battery, it was still at 12.5v the only issue that i have noticed is the voltage drops down to 9 volts when i use the starter switch. Maybe it has reached its service life already.

[@Papparratzi]

Great useable info. Additionally, unlike lead acid which thrives being topped off through a trickle charge, lithium batteries sustain damage being charged after be charged to the max. So it’s important to remove a charger once the have been fully charged. Another option is a charger like the Tecmate Optimate dedicated lithium charger. Lithium battery charge rates are the opposite of lead acid batteries. Charge rates on new batteries. Lithium batteries start off with a slow trickle charge and then reach high voltage the closer they get to be in topped off. The Optimate charger uses this procedure which produces the maximum storage charge in a lithium battery. once the battery reaches maximum charge, the Optimate goes in to essentially what would be a sleep mode and then every 24 hours checks to see if there’s a voltage drop if none it won’t charge if it does find a drop it charges. This works great on bikes. That may have a parasitic draw. This enables the user to leave the battery connected and not worry about overcharging the motorcycle battery.

[@YouMotorcycle]

Thanks for the added info! I have a Tecmate Optimate lithium charger and have been using it about a year now on a couple of lithium batteries. All good so far!

[@therealrobertbirchall]

Victron chargers are the best on the market, no argument whatsoever.

15 years ago the claim in the title would not have been that hard to believe..(I still require proof of all CLAIMS though.) But these days most things are designed to NOT LAST. It's all by design of course.

I think there's a lot of planned obsolescence, as well as engineered obsolescence (looking at you, apple iphones)... but I think as a people we need to collectively take a degree of responsibility too. What's that saying? "Thirty years ago your owner's manual told you how to adjust valves, now it tells you not to drink the oil." or something like that? I think 40 years ago, working on the family vehicle, or your personal muscle car, was just part of life... I've been working in the motorcycle industry for over a decade now, the level of neglect I see is alarming. Things aren't built as well, you're right about that, but... a little care goes a long way, and that's a trend that (like quality) seems to be falling from popularity.

[@HaroonKhan-lu4xu]

If u ain't using your bike disconnect the battery. Top it up with distilled water for lead batteries. Charge it every few months over winter period when not riding. It will stay good and last. Note u can use acid tablets they do work.

[@YouMotorcycle]

Just want to add.. For those of us in Canada, it's a good idea to keep it on charger all winter long if your garage isn't heated

[@paradiselost9946]

i have some lead acid batteries that are over 50 years old and are a damn sight better than they were twenty years ago when i dragged them back from the auto electricians. certain things to keep in mind. a battery is an electroplating cell. electroplating requires a certain voltage and current to produce a good metal. then... every time a battery starts to discharge, then is recharged... it produces a "layer"... you have to undo this onion skin and restore the plates to being good, solid metal. not a fuzzy, laminated series of "skins". this requires systematic cycles of discharging completely, and charging completely. never attempt to replace the electrolyte. it changes the balance in the cell. only top them up with distilled water, but that being said? you can get this battery, it appears dead. the cells appear to be low on fluid... throw a meter on it. no output, and a near open circuit resistance (1M or higher!). if it reads a few ohms or less... its junk. dont bother. the plates are damaged beyond repair and shorted out. yet, when you charge it correctly... the electrolyte seems to replenish.... its getting held in the plates as hydrides and sulfates... you have to release it, get the battery fully charged again, before topping up the fluid. when charged with too much current, more than the electroplating process requires? they become an electrolysis cell, and the water is leaving as oxygen and hydrogen gas. they get hot as you are driving current through the electrolyte, breaking down water, rather than performing the desired electroplating. my "secret" is an induction coil trembler buzzer thing. im feeding them spikes of several hundred volts at extremely low currents. they are fully charged when they actually read more like 16.2V, not the 14.4-8 that we are told. fed with a source like this, the battery and its internal resistance self regulates... you cant really say what voltage or current is getting shoved into them, its more of a "joules" thing. but if you try to drive them from a constant current source that will deliver that 16.2V, they become an electrolysis cell... you have to do it "sneakily"... its almost as if you pump some "charge" onto the plate, more like a capacitor, then let that charge slowly dissipate through the electrolyte, then repeat process... and you dont rely on the charging system to do the job. its the constant stopping and starting and unregulated charge currents that produces the fuzzy onion skins. a steady discharge, followed by a steady (spiky!) charge, and they last virtually forever. they not only charge up, but they IMPROVE with time. if they are short circuited due to plate degradation though? toss them! theyre stuffed! everything i do is in complete contradiction to what the manufacturer tells you to do. but it is exactly what my old 1930s book on "accumulators" tells me to do... "accumulator" the original name for a lead acid battery. none of this applies to SLA or AGM types. i have never been able to revive either type. just standard, wet acid cells.

[@YouMotorcycle]

From streetrodracer on the 1130cc forum: "Adri - the other items to add on for battery life extension are - 1) Don't use a vented Lead Acid battery in a M/C unless you're just flat outta money. Certainly not in a V Rod, EVER. 2) Disconnect the battery when the M/C is in longer term storage or top charge before battery voltage gets low. 3) Remove the battery from the M/C in extreme cold or hot garage storage conditions, take it in the better environment of the house in A/C or Heat & charge once every couple weeks inside. No need for a constant battery tender. 4) Pull the system fuse ( if easily removed ) when the M/C is in short term storage to prevent parasitic drain. 5) If you have a Lithium battery and the M/C is in regular daily service there's no real problem, unless you have a large constant parasitic drain, or the M/C sits for a week or more. In that case have your pigtail to the battery in a convenient place to plug in for 5 minutes while you get ready to ride and check tire pressures, etc. and top charge the battery. This will greatly extend the battery life, and give you a topped off battery at the beginning of every ride." Source: www.1130cc.com/threads/how-to-get-8-years-from-your-battery.446667/post-4793682

Hi, thanks for the video. I've been on motorcycles for two years and had no idea that there are AGM batteries that can't be charged with a standard charger. That's why I also destroyed the YUASA motorcycle battery, the voltage after charging was fine, but the battery didn't work, later I found out that it had a low starting current. I bought a good quality Ctek charger and a new battery. When I winterized the motorcycles, I took the batteries out and recharged them, and once a month I measure them with a multimeter to make sure they don't have a little voltage.

From research I had done to try to make the new battery last as long as possible, I bought a battery tender trickle charger, the atv stays in the garage where it never drops below 55F, and unfortunately, that battery completely shat the bed within a month (first trail ride). The store exchanged it, and the replacement as about 6 months on it thus far. Id like to do lithium, BUT, anti gravity costs almost 400 bucks, and i cant afford that, im looking at the NOCO, for 116.00, to me its worth the chance, if it lasts a year or a bit more id be pleased (with my previous luck with AGMs).

I have a 2012(mfg’d in 11/2011) 1700cc air cooled v-twin that’s still got the original oem yuasa AGM battery that has yet to fail starting it. I do not keep it on a maint charger 24/7 because AGM batteries aren’t flooded lead acid using a paste type electrolyte that’s a lot more sensitive yo drying out causing premature failure. But what have done since the battery & bike was new is put a maint charger on it 1-1.5 days max if/when the bike sits with no use over 1-1.5wks to top it off without overdoing it. That’s how & the now 12+ year old yuasa battery is still going strong. I do the same thing with the AGM battery in my classic car that’s still going strong at 13yrs old starting a high compression big block Chevy motor np hot or cold. But a lot of people don’t realize the majority of bikes sold in the past 10yrs or more have AGM batteries more sensitive to drying out when maint chargers in float /lower current float charge mode are still keeping the battery at 13.1 to 13.6volts on avg and sometimes kept at as high 13.-14v which on 24/7 can & will over time dry out non flooded newer Gen AGM bike batteries that use a paste type electrolyte that’s screened on the battery plates with little to no moisture/water in it like older gen lead acid fully flooded batteries use. Many aftermarket rep bike batteries are also AGM lead acid tech too. I got 11yrs out of the std old school flooded lead acid battery in my old car that sits s lot with non use at times hitting it with the charger every once in a while with little to no use. The AGM napa battery in the (nice weather use only car)Miata I bought for my wife 7 yrs ago (with battery age unknown) is also still going strong hitting it with a charger every so often showing no sign of weakening any time soon. Keep in mind todays car batteries last 3-4yrs max on avg & bike batteries are a bit less at 2-3yrs in avg when I consistently get 2x-3x more Srv’c life out of the batteries in my vehicles then the avg person does time after time the charge regime I use must be working to keep plate sulphation at a minimum extending battery life. Happy motoring.

[@YouMotorcycle]

Very interesting. Next time I'm in the garage I am going to check on my batteries on the charger and see if they are sitting at 13.1 volts like you said or closer to 12.7. The last one I checked last week was 12.7 though I believe. It probably depends on the quality of charger being used.

[@feloniousmonk3049]

What's not mentioned is phantom drain on a battery from electronics and computer systems on newer motorcycles with alarm systems and such. They drain your battery, so keep your battery on a trickle charger when not riding, if your bike has an alarm system on it.

I've heard a few people mention that newer Yuasa batteries aren't lasting like they used to. Did you set yours up yourself when you got it, or did a shop put the acid in and seal it for you? I wonder how many of these issues are caused by shops that aren't doing the labor on the batteries right.

It may be that these batteries have sometimes been in stock for a fair old while. I can't figure out how to decipher the date of manufacture code.

Buying it as OEM spare part from the official motorcycle dealer is usually safe and should last just like your 1. Yuasa.

@@krollpeter KTM charge almost three times what one can buy the same Yuasa battery for elsewhere. If I was to buy from KTM I would only be provided with a two year warranty. I would be disappointed if the battery only lasted three years, and obviously it would be out of warranty. Also, there is practically zero chance of a claim being successful within two years, as it is too easy for the seller to blame the bike or improper use. The risk of buying a Yurasa (and other primary brands) is too high, so I'm sticking with lithium batteries. The more advanced LiFePO4 batteries appear to be safer, not that I've had a problem with the Li ion items that I have been using around seven years.

"Credit score is more about how valuable you are in the game, not how fast you pay them off." There's a bit of a false premise there. The faster you pay them off, the faster your credit score goes up, so credit score is at least in part about how fast you pay them off...

[@RichPober]

Use only lead-acid batteries that have cells with screw caps or removable rubber-plug strips. This is so that distilled water can be added to battery's cells. The sealed-for-life batteries cannot be accessed to add water to them. You need the add water at some point because the battery's chemistry will break down the water into the gases, which won't recombine back into water but will be lost. This loss of water will happen especially if you leave a battery for a long time on a trickle charger, unless you have a really expensive one, but even then I wouldn't trust it to not dry out the battery. You can rehydrate sealed-for-life batteries by drilling into the top of each cell and using a syringe to add water to them, and resealing them with stainless steel screw. However, this is a big faff trying to shine a torch light into a cell through the drilled hole to see if the acid level is above the top of the lead plates. Also, it is good to check the battery health with one of the new electronic battery analysers, like the Topdon BTMobile Pro linked to a mobile phone with its own app, rather than just a volt meter. These calculate the remaining capacity of the battery and how much life it still has left in a battery.

Do you live somewhere with sunny winters? I don't. Winters are mostly grey and cloudy here, and daylight hours are so short during the winter time, that even on the odd sunny day you get each week, there still isn't enough sunshine to charge your battery up. Best just to take the battery out and bring it home with you and keep it on a charger at home.

[@wisecampmotorcycles8258]

I don't think would affect battery longevity. I've had good luck with long lasting batteries, some over 10 years, by looking after them. The main concern in running a lot extra gadgets, is make sure your battery and alternator will take all that load.

[@YouMotorcycle]

Good question, and well answered. If you're adding so much that you're taxing the battery, that's one thing. If what you're adding is a negligible amount compared to what your charging system is designed for, then, assuming all components are functioning properly, I think it's okay. I'm not an electrician though! You can remove just as much load as you add pretty easily. For example, when I was riding a little 150cc Vespa through the winter, I wanted to add heated grips. Those would need about 55 watts or so (I can't remember exactly, it was a few years ago). By switching the headlight, tail light, and front running lights from incandescent to LED bulbs, I actually saved MORE power than my heated grips would have drawn from the system while running on max. You could do similar if you're really concerned.

[@Jehutymmt]

What is the standard charging time for normal cahrging method and the standard charging time of quick charge for 12V motorcycle battery?

Charging time varies by battery and is usually written right on the side of the battery itself. Don't know what you mean by quick charge. Charge at the recommended rate indicated on the battery, with the right type of charger for that battery.

[@joeedwards627]

Why not just fill with acid and seal? The battery has a breather

[@YouMotorcycle]

Great question. I'm not an expert on this, but from my understanding the simple answer is "Because that's not how it's designed to work." So firstly, when you put the acid in, there's a chemical reaction taking place. That's part of what causes all the bubbling. And you don't want to charge the battery until that reaction has had time to occur completely.... so... if you just sealed it right away, you would still want to wait to charge it, and it would be harder to know when it's okay to charge it, so you're doing yourself a disservice. Secondly, yup, there's a breather like you pointed out, but the breather is designed to let gasses that build up gradually, to escape gradually. Gradually could be minutes, hours, days, whatever. The thing is, when you first pour the acid in, nothing is happening gradually. You pour all the acid in right away, the chemical reaction is starting right away, etc. and the breather isn't designed for that. I think those are the two main reasons why. I have a video on how to fill, charge, and replace a motorcycle battery here that could give more details you might be interested in: kzbin.info/www/bejne/eJ3QmKmYisioqaM

[@arielr9614]

Just as a little information tip, a lot motorcycles and cars have "Alternative" battery configurations. For both the battery and the charge system. So for example, I fall under the "not typical use" pattern seen fir ky Ford Exploer. Killed 5 batteries in in 2 years. I got tired if it and started doing tons of research. I deoend heavily on ky cars electrical system. Ended up replacing my cars default battery with a slightly larger AGM. Still had the same issue if voltage slowly creeoing down over time. I turned my attention to the charge system and how it functions. Well I learned I could reconfigure it to keep the float state at a higher level and I could also increase the point of 100% charge state up to the actual bagteries saturation state. A lot of vehicles are now coming with smart charge systems that measure how much was taken out, it tries to immediately put that back and then go to a float state. All these things were reprogramable. I leanrned a lot of other things too, but thats getting too far ibto the weeds for this topic. Now im working on imolementing something similar but dedicated in my motorcycle. One of the interesting bits along the way that was key to gelping with issues was a large banknof caps right across the terminals the initial brunt of starting is taken by the caps, insteam of the battery. Lots of cool stuff out there.

[@wisecampmotorcycles8258]

I don't like them. I've had a few, they only last a few years. You can't beat a good quality led acid battery. With lithium batteries, I've seen a few bikes catch on fire, (on KZbin)

[@posteroonie]

LiFePO4 batteries (also called LFP) can absorb a lot of amps so that might be why they don't put the charge limit on the label. And they don't catch fire. The main negative is that they get ruined by charging them when they're below freezing. That doesn't bother me because I live in the sunbelt and don't ride during cold snaps. My OEM Yuasa lasted 7 years and the LFP replacement was $70 cheaper than a Yuasa, a quarter of the weight, and I expect it to last even longer. Also great is that the low self-discharge means than I don't have any reason to bother with a charger. Coming home after my bike has been parked for 2 months it cranks robustly and fires up straight away.

[@YouMotorcycle]

I admire you guys in warmer climates! The low discharge rate is nice, but truthfully, I have a lithium-specific battery charger recommended by the manufacturer of one of my batteries, and I don't mind having the lithiums charging (I have two, I alternate the charger back and forth) every now and then.

[@jlrutube1312]

I usually just buy a cheap Wal-Mart battery and they last me about 7 years or more. I think the reason is that I ride my motorcycle probably 4 or 5 days a week all summer and all winter. I never have a week that I don't ride. I almost never use a charger and almost never need one. If you ride frequently and often take trips as least 10 miles your battery will last. Of course, I live in Oklahoma not Wisconsin or North Dakota so it's possible to ride year round.

[@YouMotorcycle]

Yup, good point. Many people live in climates where riding days are fewer and more sporadic, and many people also live in cities where they won't have a 10 mile commute. I've only ever had one job that took me more than 10 miles from home. The rest of the time I was idling in stop and go traffic on my daily commute through the city to and from work, which can be harder on a battery.

[@JDye-youtube]

I fill, charge and install exactly per the Yuasa instructions and keep it on a trickle charger. I ride 85 miles at a lick with zero stop and go. It sits in my garage so no temp extremes. The battery lasts a max of 4 years…that’s it. I’m on my third battery. For the price, it just makes more sense to use the lead acid and buy a new one every three years.

[@3FHVSP]

Battery life is affected by the average temperature. Thus, batteries in a hot climate last less than in a cold one. In addition, the charging voltage also affects the battery life. The voltage reached on an ordinary lead battery should be from 13.9 to 14.4V. But if it is higher in that range, the battery will last less.

[@JDye-youtube]

@@3FHVSP Well it doesn’t get anymore average than my garage in moderate SE Virginia near the coastline. I get three good years, then I start noticing a decline.

[@3FHVSP]

@@JDye-youtube, A voltage of 14.1 to 14.2 volts is ok. My experience is (as yuasa claims in its documentation) that charging voltage reduced closer to 13.85V gives longer battery life (at reference temperature - 15mV/°C). Some of my voltage regulators greatly extended the life of the battery because they had a very stable regulation voltage but also a small error (significant voltage drop after heating - i.e. after approx. 45 minutes) which allowed the battery to be charged first, and then kept full with some slightly lower charging voltage. Rarely does a regulator/rectifier have such a characteristic on motorcycles. In the Mediterranean climate, some batteries lasted 6 to 8 years. Battery manufacturers state that the life of the battery is also affected by the ripple current, which means that regulators that better maintain the voltage on the battery also extend the life of the battery. So it's possible that the voltage regulator has a big impact on battery life. The question is how to evaluate and compare it objectively?

[@YouMotorcycle]

Ideally, one device per battery, however, if you trust yourself enough to keep rotating them so every battery is on the charger at least every couple weeks, that would probably be okay too. Just remember that some car battery chargers are way too powerful for motorcycle batteries, so if you're going to be sharing one charger across both bikes and cars you should look for a charger with a button to control the power output so you can switch from motorcycle mode to car mode.
