I've got hella 500's on my roof rack and 1000's on my brush bar, and i've already been through one alternator. I was just curious if anybody else has mounted a second battery, and if so, how you did it. Where did you put it, how did you enclose it, etc. Also, would putting one of those optima spiral cell batteries eliminate the need for a second battery, or are they just a waste of money? Any input appreciated, thanks.   phil (Powerslide) Member Username: Powerslide Post Number: 25 Registered: 11-2002 Posted on Friday, February 14, 2003 - 01:33 am:    You can fit 2 Optima's in the OEM location on a D2 not sure with the D1 but I believe it is the same. You can buy a solenoid terminal (about $50) to wire both batteries. Don't get the cheap isolators as they don't really work. Why don't you get a higher output alternator instead. Perhaps 135 amps and up. Check out the Wrangler Products. They have alternators and the solenoid terminals.   Michael Noe (Noee) advanced member Username: Noee Post Number: 439 Registered: 03-2002 Posted on Friday, February 14, 2003 - 04:26 am:    Something like this might come in handy... http://www.aedofab.com/prod_rover/dualbatterytray.htm   Jason Bard (Jbard) Advanced member Username: Jbard Post Number: 73 Registered: 10-2002 Posted on Friday, February 14, 2003 - 01:49 pm:    If you're burning up alternators, you need to get a higher output alternator and not add a battery. Adding a battery will only allow you to run your lights when the truck is not running. When the truck is running, the alternator acts as a generator to run electrical equipment in the vehicle (lights) while keeping the charge up on the battery. Hence, when the vehicle is running the power you're pulling is actually from the alternator and not the battery(ies).

A second battery will not help and will just work your alternator more to charge-up a bigger battery.
