How To Set Up Dual Auto Batteries 1996 Chevy Tahoe Yellowtop Optima Battery

[@dragonslayer4135]

After 6 years, the video is still helpful. Thanks💯

[@stevenmorin2766]

To the viewers with interest in this process presented in this video. This was my Tahoe. Never had an issue come up after this install was performed. I’m sort of upset though after reading some of these comments about installing an isolator with this set up. After never having it fail me, I didn’t know it could get better than working perfectly for so long. -Great job sir

[@gilchevy]

great video looks like you 2 had fun and it is very informative as far as isolating battery I think that's a choice do what you want awesome

[@stevenmchenry8417]

Nice video. Some people are going to hate no matter what you do. At least you helping people that really need. Keep up the good work.

Where did you get the battery tray for the drivers side. I have a 96 Silverado with a storage box on the driver's side. Wondering if you had the same setup.

[@jessewilkie5762]

My came factory with extra battery box some do some come with the storage box

[@tysoncurrie7745]

Good video, BUT you shouldn't mix two different types of batteries together just like you should never use an old battery with a new battery because one will always drain the other one. Always replace both batteries together new and use same type of battery so they don't have any issues connected together.

[@livingonadollar2882]

1 gauge welding cable a copper lugs with a crimp hammer shrink tubing and dielectrical grease Cut to length no need of coiling extra left over wire that has power having to travel a longer distance. Add in 3/8 bolts with a few washers and a lock washer and nut for side posts You now have a thicker wire resistant to heat and everything is still cheaper than buying ready made wires and kits Also look into alts with a higher Amp output I swaped my Blazer CS-130 which was a 85amp to a 145amp for around the same price as the first one

[@zap265]

leaving the batteries connected in parallel will wear down the stronger battery while it tries to charge the weaker one. isolate one for starting and only connect them when key on, or oil pressure, or something. nice crescent wrench

[@outdoortradesman142]

Sorry but I disagree - Couple things. One, I was using the tools out of my HVAC van. Lol. Worked, didnt it? I have more tools than I know what to do with. 2 - There is nothing wrong with a charged battery discharging energy into another battery. That is the point of a battery. To discharge energy. Granted, over the lifetime of a battery you only get so many charges and discharges, but the number is very high. If you are using the batteries only when the car is on and using the the alternator (upgraded amperage in a more demanding system), both batteries should only ever need a small surface charge to stay topped off. The point of having a deep cycle as a second battery in a system thats demanding, such as if you had subwoofers, is to act essentially as a large capacitor for long bass hit draws, which a high output alternator should quickly recover from in between bass hits, not to mention you will likely not be playing full volume your entire drive or everytime you drive and the demand is much less at lower volumes. I think people think you need an isolator and don't even know why. In my view the only need for an isolator would be if you were in competition and played your audio system with the vehicle off. That way you don't drain your starting battery dead while the car is off. Or, if you were trying to be overly protective and in the event of one of the batteries failure, to protect the other one. But just because you drop a cell in one battery does not mean it will instantly ruin the other and it should be noticed pretty quickly in your systems performance if you are mindful. This is the way I've done it in multiple vehicles over many years and never had to replace any batteries, including in a 3500 watt RMS system. This is my opinion based on experience. If it makes you feel any better, when I was the lead tech at the last shop I worked at, I often argued about the principle of replacing OEM dual batteries in pairs. Tech B would say on a diesel for example if one battery is bad both should be replaced. I wholeheartedly disagree.

[@zap265]

@@outdoortradesman142jon, i have some experience too, and i'm telling you the stronger battery will have reduced useful life if it's surface charge is always getting pissed away into a weaker battery. that said a relay is pretty cheap and my second battery is only connected to the charging system (and oher battery)when the key is on. i dont have a killer soundsystem, i have cameras and recorders. they are on the deep cycle non-engne starting battery.

[@zap265]

@@outdoortradesman142 ....and the point of a battery is to store electricity to be used later, not to piss away it's charge on a dead battery that wont give it back

[@outdoortradesman142]

@@zap265 Yes, I understand, and I am not trying to diminish your experience. However we will have to agree to disagree that this is "bad" for the battery. A battery charging and discharging is a battery's purpose in life.

[@ModernDayTemplar606]

Late reply but on your 99 tahoe do you have space where the extra battery goes ?

[@americanwhiteboy715]

Friendly suggestion is use a heat shrink tube when you connect the ends and two wire together instead of the tape

[@dier-tr3ox]

Lol, nothing better then working on cars and Beer...Thanks good video

[@peteandrepete528]

Pretty straight forward. Good idea by GM and putting that second battery tray under the hood just in case.Beats having to run your wires to the back and saves you from having to manufacture another tray yourself.Does your main starting battery need to be stronger or at least equal in strength to your new addition or will a stronger alternator smooth that out or as long as it's getting the proper charge it's all good?. Thanks guys.

[@paulsbuilds1982]

Has to be matching capacity he should have installed a isolator

[@kingzionmusic]

@@paulsbuilds1982 I have a 98 2Dr Tahoe so u mention adding isolated. Question 🙋‍♂️ I have is let’s say I have 100 amp Alternator though that’s not enough for all accessories am I good because I have 2 battery’s?

[@photog1529]

I have a '95 4WD Suburban...unfortunately that model year didn't come with second battery location. I have an air canister in that location...hopefully I can remove it without messing up the ignition and MAP sensor.

[@Catholic1391]

I plan to put and 2nd battery on a 2013 Tahoe for my Amp. You think it's ok to hookup the + from the 2nd battery straight to the alternator. Plus I will be doing the big three upgrade. On the 2nd battery

[@outdoortradesman142]

No I do not recommend hooking both batteries to the alternator. Alternators work partially on demand according to how much energy they need to produce. If you have them both ran seperately to the alternator if one battery is charged and the other is not it could theoretically overcharge the charged battery and cause damage.

[@Catholic1391]

Ok than, on the main battery I will run an other pos 0 gage wire to the alternator, than from the main 1st battery to the 2nd battery than to a 3rd battery. The 3rd battery will hook up to a Orion HCCA 3000.1 will that be ok I do plan to upgrade my alternator.

[@mikedyess1340]

I did mine this way with my 09 avalanche. I bought a new battery for my main and used my old battery for my secondary battery. But found out my old battery was draining my new battery. So other I'm buying a second new battery the same one I bought recently. But I'm also buying a battery isolator as well

[@outdoortradesman142]

In a case where the batteries are connected without an isolator, and one battery is bad or on its way out going bad, it CAN take the other battery out. This is a "risk" of running this setup. Typically though if one out of 2 goes bad, you'd replace both anyhow though. Like in the case of dually trucks with factory dual batteries. One goes bad, dealership policy is to replace both regardless.

[@kingzionmusic]

@@outdoortradesman142 please answer this for me I have a 98 2Dr Tahoe same extra bay for battery 🔋 same truck 🛻 pretty much my question is do I still need a high output Alternator say 140-160 with 2 battery’s? Or am I ok 👌 with the stock 100 amp soon I will be running 2 12’s sound system a TV 📺 or 2 windows all are automatic as u know. So that’s my main question.

I want to do this same thing on my truck , I have 2 of the same trucks one is the back up. I just want to put my spare in the extra tray and charge while i'm on the interstate, it wont be hooked up forever like this set up. Can I keep my factory wires and just run a new positive to the spare battery and ground the spare to the truck? Just keeping all the factory hook ups to the primary battery?

[@jamespham2895]

You should run the positive cable first for safety reason. Just a suggesting

[@outdoortradesman142]

Yes, I was always taught connect the negative last. However, it has never caused me issues. I have gotten lax about it. Good call

The 2007 Tahoe has this weird + battery hookup, with a long red plastic cover, and some weird slot thing in a long rail. I don't know how, you hook another wire to it.

Use the slot on the firewall right behind the battery ,it has a 10or 12 mm nut

Up to you whether you would like the added protection of an isolator or not. As of Jan 22 2020 this vehicle has been running fine in this setup, without a single issue.

I have run my international truck over 500 thousand miles with 3 batteries in parallel with NO isolator and it has worked fine.

[@gabrielbridges1940]

What did you upgrade your alternator to

[@outdoortradesman142]

Higher amperage alternators are available online for reasonable prices.

[@NeilKudro]

The question: I just added a new 2ndary battery in my 01 Silverado 8100. This is how I connected them, I connected the positive wire from the 2nd battery running through a fuze and a solenoid to the positive end of the primary battery. the negative wire from the 2nd battery into the frame. Is this correct?

[@javi1373]

Yes that actually how you supposed to connect them that a parallel hook up which it's a 12v set up

[@javi1373]

Or you could do it like they did, but with an isolator

[@stevenmorin2766]

I’m also curious about the set up. If done as shown and minus the isolator, what problems might occur?

[@NeilKudro]

@@stevenmorin2766 You know, since I ran the second battery with the same connections, both batteries go dead in couple of days. I got sick of charging batteries, so I plan on taking off the secondary battery all together.

@@outdoortradesman142 well snap-on's kind of gone downhill drastically in the past few years and in that case I would understand a crescent wrench I guess. I do have a question though since you replied and I'm not a certified mechanic. But is there a reason you did not utilize the wire that goes over the fan shroud that runs from the battery or actually a little terminal block on the core support to the main fuse box over the driver's Tire? And is there a reason that that would not work?

So don’t be cheap yet y’all bought a battery that is considered cheaper that most of the car audio AGM batteries that are pure 99.99 % lead and more of it then the optima I used to have the yellow top in my Jeep and it was ok for starting n factory system but larger system needs way more power on demand and that costs a buttload.are both those batteries the same cranking amps????? Did u run them is series or keep them separate.larger wire size with more strands are best like 1/0 age shit there’s 8/0 awg now Steve mead has a video that shows the size of almost a quarter in thickness.

[@outdoortradesman142]

you don't seem to have really any idea what you're talking about at all. You sound like you've been watching a bunch of car audio pros running competition setups with crazy demands. You going to add all that garbage to add a little 12 sir? no. no you aren't. or a winch. no. no you aren't. Thanks though.

[@marknowakowski6590]

Actually i run two 500 rms watt alpine mono block amps on one duel voice coil sub alpine type R series 750+rms watts. Four 100 watt rms woofers on alpine four Chanel amp, four mids and tweeters as separates on alpine two Chanel amp and it’s ok for now. Head unit is an older alpine from 2007/8 model year as I’m still living old school with cds and I-pod touch 4 from 2010/11 with the added pod cable on back of unit plugin. Duel 2 gage Big 4 upgrade/ duel alts and duel batteries both AGM style 1000 cca, stereo shop ran 1 gage back to rear then blocked into 4 gage to all amps +/- wires 8 gage to sub wires +/- per coil x2, None of the car harness wires are used for speakers only ignition switch head-unit on/off. Also amps are turned on/off by the head-unit. My lights don’t flicker even when at a stop light and my amps stay cool and don’t go into protect mode ever not even the four Chanel and it pounds well enough for me.

So I’m sure a lot of viewers would like to had power pulling ideas to there’s vehicles and watched this video to see what the guy who presumes to know the process has to say about it. But the one thing this video shows mainly, is, one way to install a dual battery in a truck with a factory system and know extra accessories such lights, wenches, ext. It’s a proven sure way to had a second battery, be it the similar or exactly matching, to an AMG car battery in a vehicle to prevent needing, but not having extra electricity in case you ever need it. Say like in a place where weather can be 60 degrees at 4pm to below freezing at 11pm like bipolar Indiana. Where there’s a scare you might, one random morning, not have enough juice to start your classic internal combustion engine for work the next day. It’s about dependability and piece of mind. I must admit. This was actually my 96’ Tahoe in the video, and as of today, I’ve driven this heavy crossover packed down with 100’s of lbs of tools over 54k more miles since installing hat 2nd battery. I’ve never had my cranking battery fail. Great things were done in this video. I bet you advertising that other guy on this video gave him a key board b*n*r. -Enjoyed hearing from people.

Not a true 12v dual set up. You are running to much volts to a 12v system. Asking for problems. I burnt my pcm/vcm becuz I didn't run parallel dual batteries. Positive to Positive and negative to negative battery. Then ground everything from main battery.
