thinking of dual batteries in a 3rd gen

northfacer581 · 11-13-2005, 07:38 PM

im thinking of adding a 2nd battery (have an old optima sitting around that i might as well use). i dont want to put it under the hood because of lack of work ethic to move stuff around and whatnot. i just dont feel like making room to fit a red top optima. i plan on putting it in the cargo area, also because i am buying an air compressor, which has battery clamps, and id like to pretty much hard mount the portable compressor. anyways, i was wondering how long the battery would last if i didnt hook up the alternator to it. any feedback would be appreciated.

Not very long at all. We are talking hours (1-24) here, that's all I know.

Im interested in this also.

garrett1478 · 11-13-2005, 07:43 PM

yeah....probably not long, i guess it depends on how much you used it (or does it?) i've seen people use 2 optimas in the stock battery space, so it would be minimal work. if i were to get a 2nd battery, thats what i'd do, and then run 4 guage to the rear to a fuse block (much like bob's write up).

Where does it say ANYTHING about running a battery without it connected to an alternator? If there is, sorry, hand down. But if there isn't, you guys are going overboard.

northfacer581 · 11-13-2005, 07:59 PM

ill admit i searched mininimally, however what i searched, i couldnt find the answer.

Localmotion · 11-13-2005, 08:00 PM

maybe he was trying to get people to post in the same thread about the same topic.

that was my take on it....and besides, i think its almost pointless just to have a battery sitting back there. i can't see that being practical for very long. just my opinion.

By that logic, we wouldn't ever have ANY new threads. Almost.

hmmm.....i didnt say that there should be only one tread about each topic...i just said maybe he tried to get things a little more organized so when people in the future wanted some info...then BAM!!!! there it is. AND by having all related questions in one thread, that doesnt have a lot of info here on YT, makes it easier to find/ask questions.

northfacer581 · 11-13-2005, 09:38 PM

i hope i didnt create any mess by creating this thread. i just wanted to know the best solution for my situation, and you cant always get that by searching.

after browsing around, i think i will opt for a solid setup. not just a hinky dink job with a few wires connected to a battery in the trunk so i can run some lights. i will start gathering parts this week, and hopefully be able to tackle it sometime soon. hopefully running wires from the alternator back wont be too tricky. on that same token of wanting a solid setup, i dont wana go overboard with it. i should be able to make the best of both worlds on this though...

Localmotion · 11-13-2005, 09:40 PM

no mess started.

98LimitedCustomized · 11-13-2005, 10:15 PM

What is your reasoning for wanting a 2nd batter? if it's just for that compressor you're much better off just running some 4 guage back and tapping into that for your compressor. I'd recommend a distribution block for future upgrades. Having a battery just sitting back there with no charging means is downright rediculous.

Hes running a lot of aux lights too.

98LimitedCustomized · 11-13-2005, 10:24 PM

who runs their auxiliary lights for long periods when the vehicle is off? Let's not forget that your battery is a storage device, the alternator does the work when you're running.

northfacer581 · 11-13-2005, 10:34 PM

i know the alternator charges the battery/pretty much is the battery while the engine is running. im simply looking to make sure that i dont kill my one and only battery with all these accessories i have/am going to be adding. i have 11 lights on my roof rack, and more to come. when i turn on one set (front ones), then rear/back ones, they become dimmer. i do not want this.

and ill tell you when i run my lights for long periods when the vehicle is off. while were camping. my friends and i enjoy a good game of poker, and our lanterns arent bright enough. we enjoy having ample light, and my lights provide this. also its quite nice to be able to have plenty of light for setting up tents/firepit/whatnot. its getting real dark real quick now, and we dont get out till later, so our mag-lites just arent cutting it anymore.

i also will be getting a winch for christmas, component speakers within the next few weeks, and the compressor. i would love for everything to be able to run at peak performance all at once. why not?

98LimitedCustomized · 11-13-2005, 10:37 PM

I've got the dualies for jumpstarting purposes mainly, but also for those reaaaaally cold mornings when 24 volts is more appetizing to the starter. With the isolator I have, I can switch them together. Picture this: you're tailgating at a football game, rocking the tunes and watching the pregame on a TV hooked up to your inverter. After a few hours, everything shuts off, your battery went dead... big deal, flip a switch, start it up, and charge it back up. Or, you leave your lights on over night and have a dead battery in the morning. Flip a switch and you're on your way, not even late. I also put the 2nd battery in for future aspirations, namely a winch. I wouldn't need it, but with 2 batteries you can have a 24 volt DC welder under your hood too.

LOL..those are the same reasons he wants one.

crappled · 11-13-2005, 10:41 PM

Uhm, nothing will fit under our hood LOL

why not get a battery protector? cuts off the pos terminal to the battery if it gets close to draining.

northfacer581 · 11-13-2005, 10:43 PM

ok well i like that idea. so ur saying i should hook the batteries up in case i have trouble starting up?

right now im just looking at having this second battery to run most of my accessories, and all i really need to know is how to wire it up so that its charged by the stock alternator. thats what i would like help with please.
