Question... My computer is running my battery low I think and once I add an amp or two or three forget it. =) My question is, I know alot of people have a second battery in their car but how does it recharge? Can someone explain this to me?

Thanks.

in my old car (1994 honduh prelude) i added a second battery just for my stereo and things i added on b/c when i was driving with my stereo blasting the lights would dim like crazy, especially at a stop. I had a second alternator put in that i found at a junk yard and mounted the second battery in the trunk. i had this done for me so i cant tell you how to do it but i want to do this on my MAX as well so any help would be appreciated for me too

 

Add a dual battery isolator. I had one in my old car made by phoenix gold($195.00). It allowed one alternator to recharge two batteries without the added expense of two alernators,custom bracketry, and trying to find belts that fit. good luck

 

You will need a battery isolator if you use just 1 alternator. If you just hook them up without one they will try to recharge each other and they will kill each other pretty fast.

 

you did lots to yours wow I like, wish I could say the same wit mine.

 

Doesn't it just put more load on the alternator and eventually kill it?... this is what my local audio shop told me because, if you have a lot of current draw, whether u have one battery or 2, by adding another battery you are just increasing the load. i was told that the best upgrade would be a new alternator with a higher output
