Carroot1 Posted October 19, 2010 Report Share Posted October 19, 2010 Hey, so my voltage is at 14 volts then when the lows hit it drops all the way down to 12.9. I have a walmart battery under the hood and a stock battery in the trunk. I have a 1999 Bmw 323i and im wondering what kind of battery to get without breaking the bank. I don't want to buy an alt:( thanks Quote Link to comment Share on other sites More sharing options...

Carroot1 Posted October 19, 2010 Author Report Share Posted October 19, 2010 im also thinking of doubling my power from an aq1200d to an aq2200D will my voltage still be fine? Quote Link to comment Share on other sites More sharing options...
Carroot1 Posted October 19, 2010 Author Report Share Posted October 19, 2010 my budget would be 200 dollars for this Quote Link to comment Share on other sites More sharing options...
ChevyBoy95 Posted October 19, 2010 Report Share Posted October 19, 2010 (edited) Low voltage as 13 isn't bad at all. Before my new battery(hc2400, think that's what it is), I would drop to 11. Edit: with 200 you probably couldn't stop 2kwrms from having voltage issues. Only thing close to that price would be a HO alt for like 280 that would be 220 amps.

byers319 Posted October 19, 2010 Report Share Posted October 19, 2010 well lets think about this, twice as much power... requires more power... =volts drop faster Quote Link to comment Share on other sites More sharing options...
dugee81 Posted October 19, 2010 Report Share Posted October 19, 2010 If you don't have an alt powerful enough to provide for the amperage the amps are requesting, it will pull from your batteries and drop down to the battery's resting voltage eventually..

ChevyBoy95 Posted October 19, 2010 Report Share Posted October 19, 2010 And it will put strain on your alt if you add to many batteries and no HO alt.
