greg4510 Posted February 21, 2015 Report Posted February 21, 2015 Hey guys I need some opinions on these batteries. I have a buddy of mine that can get me group 34 optima yellow tops from his job for $80. Ive heard a few people say they don't think they are that good but at that price brand new with warranty its hard to pass up. right now I only have a stock 160 alt in a 2007 escalade(plan on changing it to a 250) and I know my amp draw will be about 350 amps. im not looking to burp its a daily driver and I just want the voltage to stay around 13.5-13.8. If you would get them give me an idea I may can get away with
Miguels Posted February 21, 2015 Report Posted February 21, 2015 your voltage will not stay at 13.8 or even 13.0 no matter what battery brand or the number of them.. you have 350a draw and only 160a alternator. batteries dont make power they just store it even if you get a 250a alternator your voltage will hurt with a 350a draw.. what amp are you running and why do you think you will draw 350a? my logshttp://www.stevemead...-my-new-set-up/my blow through loghttp://www.stevemead...future-updates/ 96 ss http://www.stevemeadedesigns.com/board/topic/164094-96-impala-ss-build/
greg4510 Posted February 21, 2015 Author Report Posted February 21, 2015 2 powerbass asa 600.4 (60 amps each) and a kicker zx2500.1 (230-250 amps)
rockFord_Expedition Posted February 21, 2015 Report Posted February 21, 2015 Thats pushing it on an OEM alt. Yellow tops aren't too bad, but they aren't the best. At $80 a piece how many do you have in your budget? I would take that cash and buy a good alternator. Make sure you do your big 3, and do it right.

greg4510 Posted February 21, 2015 Author Report Posted February 21, 2015 see I can get 1 kinetic hc 2400 for 259. im just looking at I can get 3 optima group 31 for 240 they say they have 75 ah a piece. at that price I can get as many as I want
Miguels Posted February 21, 2015 Report Posted February 21, 2015 you wont draw 350a a 250a alt and 2 batteries should be fine.. 1 group 34 up front one group 31 in the rear maybe 2 my logshttp://www.stevemead...-my-new-set-up/my blow through loghttp://www.stevemead...future-updates/ 96 ss http://www.stevemeadedesigns.com/board/topic/164094-96-impala-ss-build/
greg4510 Posted February 21, 2015 Author Report Posted February 21, 2015 ok what about 1 group 31 upfront and 2 group 31 in the rear. I have 2 runs of 1\0 so it can supply power to the rear.
rockFord_Expedition Posted February 21, 2015 Report Posted February 21, 2015 OP, you're talking reserve, and that is pretty much the topic of this thread, but reserve isn't going to be your issue. Old School/New School RF Build March 2015 SOTM Winner How to crimp large wire
greg4510 Posted February 21, 2015 Author Report Posted February 21, 2015 What do you think my issue may be then because i assumed i needed my ah to match the amp draw
Kyblack76 Posted February 21, 2015 Report Posted February 21, 2015 your voltage will not stay at 13.8 or even 13.0 no matter what battery brand or the number of them.. you have 350a draw and only 160a alternator. batteries dont make power they just store it even if you get a 250a alternator your voltage will hurt with a 350a draw.. what amp are you running and why do you think you will draw 350a? perfectly said.. adding 12v bat's wont RAISE your voltage... nor will adding more runs...... well done..
