[QUOTE="loopkiller, post: 5718012, member: 601690"] I am not against batteries, but if all he did was buy a battery, then he would be back here in a few weeks with a dead battery. He needs to keep them charged one way or another. Here are the options: 1) Turn down the music (no fun option) 2) Upgrade alt (expensive option) 3) Charge batteries when car is parked (cheaper and easier if car is garaged) Now I know the OP is from Canada. He has to be careful what size battery he buys. When you are the far north, you have to have a beast of a battery to start the car on very cold days, unless it is garaged. Even then, if you went to the mall or something and the car sat outside, you still need that battery power. I would highly suggest the following: 1) Keep stock battery 2) Install diode based isolator 3) Install rear battery (Largest you can afford; HC2400/9A31/D3100/2150) 4) Buy a power supply / charger to keep the rear battery fully charged when parked This will get you by until you can install an HO alt in your new car.
