Optima yellow top 900cca (D31A)

I just got a couple of questions with this battery.

-Do i need to change the stock altenator to run this in my car (to recharge it whilst able to drive around so i never have to use a battery charger).

-What voltage will it run without car engine on when its fully charged

-Or anything i need to know before i buy this battery or recommend another battery for a similar price

-Also any recommendations of where to get it or should i get it through car specialist places (northfield hehe)

If i do get a battery charger, might get a MULTI XS 25000 cause it can be used as a power source (for when i wreck my car and audio goes in the house)

-No, although it's a good idea to upgrade your alternator too. I'm fairly sure we have a Bosch unit so just take it to an auto eleccy and ask them to rebuild it with Falcon internals.

-Battery doesn't determine voltage, the voltage regulator does.

-Not really. Good batteries, but there are other routes you can go (audio dry cells, deep cycles, etc).

-Wherever you can find it cheapest.

i also got a yellow top battery too when i was running my system, no need to upgrade the aternator as i had no problems. sick battery but, went to a drive thru movie, watched 2 movies with my system thumping loud, (500/1 + 1000/1 amps, 13W7 sub) and didnt run flat at ALL. the person parked next to me also had same car, their car died about 2-4times. hahaa
