E-Bike Battery Care & Maintenance Tips!

[@VadikRamm]

I wish there was a recycling program that would incentivize people to recycle their old batteries in exchange for extra credits that people can use towards purchasing a brand new battery.

[@HoonGoon]

The shop just recently purchased my trek rail 9.8 gt from said i can bring the battery to them to recycle for free. I guess you usually have to pay to recycle them? Im new to this.

Specialized gives you instructions on the battery itself. Charge at least once in 30 days at room temperature, do not use at below -25 or above 40 C. Store at 50-60% charge. Since my second boy was born I am unable to ride as much as I did and I do need to store my battery from time to time. Very helpful, thanks Specialized.

[@seakayak4425]

Every now and then this channel actually gives sensible advice,I have experienced battery degradation due to charging straight after cold winter rides,definitely get them to room temp first or at least not 5c or so

[@350zbn]

Great tips from you guys as always

[@embn]

Glad you found these tips useful! Thanks for the support! 👊

[@silviu.filipescu]

I generally charge my eMTB battery just before the ride to 100%. After the ride it remains generally to 10-40% with state of charge for few days or weeks till next ride. I also keep 20-25% state of charge over the winter for 3 months. I rarely discharge the battery to 0% on a ride. This happened 4 or 5 times in 2 years of use. Now the battery have 45 charging cycles and I do not feel a drop of autonomy. I store my bike with battery installed in a shady place on the balcony where the temperature is maxim 40 C degrees in the midday of summer and minimum 10 C degrees in winter.

[@CMZPICTURES]

Ooooh, I've been charging mine up at the end of every ride. This is great info. Thanks!

[@adamotheloanguy]

Me too. Good to know

[@JCbiglessworth]

Depends on what battery you have, bosch batteries have a management system where you can charge it fully without issues

[@Whoadayson]

So, tell me what all your opinions are on this situation: I bought an ebike for a great price, it arrived with the Shimano battery 100% completely dead, NOT BMS protection dead, but fully dead, zero volts, no sign of life dead, and when I went to charge it, it did not take a charge, beside a watt or two (I was using an inline power meter) but finally about an hour after plugging it in, it started a slow ramp up to full 80 watt charging. It was due to take 6ish hrs to charge a fully dead battery to 100%, mine was still charging at full 80watts after 7hrs and my meter was showing 580wh already pushed into my 504wh pack, but the pack wasnt bulging and I didnt see any heat on flir or by feel so I let it go, in about 5 more mins it started to ramp down and in 5 more mins it was showing fully charged. At charge completion it showed 585wh total. A partially charged pack even if shut off for storage or the BMS going into protection mode wouldnt allow more than 400wh in before full, so I know this was dead as a door nail. Now, what Im worried about is when will this pack start its delayed but inevitable exponential decay in capacity that most lithium cells face a few yrs after its left at 0 volts for extended amounts of time (on my pack, I figure several weeks at min!) and will it fall in or outside of Shimanos 2 yr warranty, and will that warranty even apply to me if its above 60% cap at that 2yr mark, which it may well be since Im a light user (estimated 100 charge cycles over its 2yrs-far from the 1000 cycles they claim-my point is, my own use wont be as much a factor in the evolution of this packs decline, which may hurt the chances of it reaching

[@doepicchet]

If charging in your home I would charge in a fireproof battery bag. Also great for storage.

[@nickfitzhugh7156]

You can extend your battery life (ie number of charge cycles) by up to 2x by only charging it to 90%, or even up to 3x by limiting charging to 80%. I think the 1000 charge cycles estimate is improbable, more like 300-500 depending on the cells used in the battery, although obviously this depends on what your definition of end of battery life is (IMO 60% capacity is pretty unusable!). For someone who rides twice a week that would mean only 3 to 5 years of usable battery life. If you're doing shorter rides that don't require a full battery, best to only charge to 80-90% to extend the usable battery lifespan.

[@YoStu242]

I have followed 40-80% rule with my mobile phone, meaning I have tried not to charge past 80% and not let drain below 40% and after ~5 years battery has lost about 10% of it's rated capacity. I suppose same applies to all li-ion batteries altough e-bike as such crude charge indicators so it's hard to tell the percentage. I suppose it's enough when I stop charging when it's 4/5 bars full and not let it drain below 2/5.

[@DKFX1]

@@YoStu242 That's pretty impressive, I had mine for 2.5 years and used a 20-80% rule, but I can't say I haven't slipped up occasionally. It was at 93% 1 month ago. Now I've used for it 4 weeks as an internet hotspot(not keeping the rule) and it's already down to 91%

[@vashon100]

[@Destide]

Great tip about the dielectric grease, so many people smother contacts with, it's for insulating water ingress. Just my opinion and not factual at all, but for the contacts isopropyl to clean and acf50 to stop corrosion use an insulating soft brush, wire wool not recommended :D.

[@HaggisPower]

Electrical contact cleaner is designed for exactly this and leaves a very light oil residue on the contacts. I had the motor out the other day and put silicon dielectric grease around the inside of the connector shrouds but not into the contacts. Anything to keep water out while keeping good contact...

[@stevetremlett7917]

My Giant owners manual says to completely drain battery every 15 charge cycles in order to maximise battery life.

[@205RallyTeam]

Hmm what do you recommend with a 2023 Mondraker Crafty RR as battery cannot be removed.

[@OGBandit1]

So are you talking Celsius? 20⁰ seems a bit cold for storage. I was told to make sure you are charging to full before a ride as the bms with balance the cells.

[@WalterBurton]

@@OGBandit1 : The BMS lives inside the battery pack. It will keep your cells balanced as the charge depletes. No need to fully charge to balance cells.

[@davidmacdonald4922]

Any good tips on whether you should protect the connection terminals on the bike when transporting the bike after the battery has been removed? On a towbar rack, for example, there is going to be a lot of water spray and crud flying around that area when driving at any speed. Are covers available, or any tips about making A DIY cover? Thanks.

[@hobblyjig]

Do brands offer apps to manage charging? Like setting it to charge to a certain percentage? Or set to charge by a certain time. What brands do have that?

[@Patrick-vu1pn]

Giant has a button to charge the battery to 60%

[@Lee-ic2yn]

I have shimano ep8 with 630wh, but hope the come with a ballancing on their firmware app. Sometimes you fully charge your ebike, but for some reason could not ride for weeks and batt keeps fully charged

[@JoLe1991]

a decent BMS should prevent charge current from reaching the battery below 5°C. I'm developing a battery (based on 21700 cells) with temperature dependent heating element that will turn on below 15°C when the charger is plugged in. Without a charger, the heating element cannot turn on and use up battery capacity to maintain temperature. The aim of this automatic heating system is to have a battery which can be charged in cold conditions (obviously insulation is required to keep the heat), i.e. outdoor solar chargin in winter.

I know the big players are good at their batteries and safety systems, but a word of warning to those who feel 'E***' can provide a cheap alternative to the real Ebike world. As an Electrical Engineer of 40 years standing, I can say that Li Ion batteries are not the answer. Better is to come, and to those people who bought cheap Escooters and Ebikes, sorry about the fires. Energy density in modern batteries is frightening.

This is the fact about these batteries and in fact is the fact about all lithium batteries when you store it you want to store between 75 and 80% energy and that's a fact you do this and keep it out of the heat you'll get the life out of your batteries I've been in the battery industry for over two decades now it's really just that simple and what happens with these batteries is there's many cells in there and you get one cell of all those cells that go bad in Elvis and you can't charge it because of the smartcharge technology United tear it apart find the one bad cell give it a little bit of a jump put it back in and all the sudden your battery pack is brand new again
