For maximum dependability, whats the best type of battery to get? mine has died 2x, b/c i'll be playing my stereo on the "on" option. but engine isnt runnning. whats powerfull enough to just get a good battery and not a cap for my system?

 

I heard the Optima battery was really good. Don't have one myself, just know people who do. You can mount it any way because it has gel inside instead of water. Also has different color tops if that matters to you. Only down side is it's kinda on the expensive side.

 

The money you spend on a new battery you could spend on something alot better. Just stop listening to the stereo with the engine off for long periods of time. Doesn't sound like anything is wrong with your battery, you just expect it to hold a charge forever.

 

lol for real. if you want to listen to the stereo, just take the car for a long drive and you'll listen as long as you want without running it dead

 

no matter what battery you have in whatever car if you run the radio, system or no system without the car on it will kill your battery overtime it may not die right away but it will certainally take life of the battery! if you want to listin to the radio i suggest you turn on the key

 

Ive got a Yellow top(best one they make, Red is cheaper but not as good) Otimus, I think it was around $150, before that I had some cheap $60 battery, now I can run my whole system, Deck, 3 TV's and DVD or gamecube . and I can run it for a while, good for indoor shows when you cant run the car and they dont have electric setup.
