[QUOTE="Steven, post: 61932, member: 544311"] I highly don't recommend running the batteries in series. This will reate a 24-volt system. All of your car's electronics (stereo, amps, computer, etc.) will go up in smoke. I think the guy meant parallel. If you connect the (+)'s together and the (-)'s, then conect one of the batteries as normal you will maintain a 12-volt system, much safer. Just remember, adding a second battery will only prolong the time that you can run yer stereo without the engine running. The second battery will just be another load for your alternator to keep charged, so when the engione is running you won't have as much extra juice as normal. [/QUOTE]
