jojo42 Posted November 29, 2010 Report Share Posted November 29, 2010 I have a 99' Explorer Sport and I was wondering if it'd be a bad idea to stick a battery in the back if I only have the stock alt, I currently have a Yellowtop under the hood and my voltage is still meh. I know it'd be smart to just get a H/O alt, but I already have another battery sitting in my basement and it'd only cost me the price of buying a in-line fuse to put it in. Would I have charging issues with the stock alt or would I be fine? Quote 2012 Ford Ranger: Build comming soon!

dugee81 Posted November 29, 2010 Report Share Posted November 29, 2010 (edited) 1. Make sure it doesn't expel fumes, that would be dangerous to your health 2. I would recommend also doing big 3 to just smooth things out a little more. I ran 2 batts in the rear with a stock alt on my current amp and I was fine. Had to charge It up every so often but it worked alright Edited November 29, 2010 by dugee81 Quote 200a alt. by Excessive Amperage hc800 under hood & 2 Deka 9a31 in rear 1/0awg + big 3 SAZ 3000D HDC3 18" @ 2 ohm Link to comment Share on other sites More sharing options...
skittlesRgood Posted November 29, 2010 Report Share Posted November 29, 2010 it'll be fine. just be sure that the second battery is an AGM like the yellowtop Quote If I answered you in a well mannered, informative way, you asked a good question or had a good attitude.

Type RF Posted November 29, 2010 Report Share Posted November 29, 2010 You really should get a alternator. A second battery will load the alternator even more and may result in even lower voltage overall.

dugee81 Posted November 29, 2010 Report Share Posted November 29, 2010 It definitely wouldn't hurt, unless it was a wet cell that would fill your cabin with fumes. Nooo good! only true way I can see it killing your alt is if the battery had a bad cell.

Nooo good! only true way I can see it killing your alt is if the battery had a bad cell. Yea, just checked, both extra batteries I have sitting in the basement are both wet cells =/. Could I maybe stick the wet cell under the hood and the optima in the back, or bad idea? Quote 2012 Ford Ranger: Build comming soon!

dugee81 Posted November 29, 2010 Report Share Posted November 29, 2010 The optima IIRC is AGM, correct? You should be fine. You should also check the voltage on the wet cells before putting them in, how long have they been sitting?

skittlesRgood Posted November 29, 2010 Report Share Posted November 29, 2010 no, they really shouldnt be used together. i mean you could do that, and it would help, but... they just dont work well together.

jojo42 Posted November 29, 2010 Author Report Share Posted November 29, 2010 I've only had the Yellowtop in the car for about 5 months or so, maybe a lil less and the other batts been sitting in the basement since then, but they're off the ground, not just sitting on concrete.
