I just bought a 130 amp alternator because mine was bad. The thing is, my battery has been near-dead for so long because of the weak alternator that now it cannot retain a charge for very long. I am interested in getting a higher output battery. I believe the Civic battery has 450 cold cranking amps. I am looking to get one that has 650 C.C.A. Is there any downside to doing this? Will this be detrimental to my electrical system or audio system in any way? I remember a good friend telling me in the past that it is not a good idea to go over the manufacturers original output on the battery. Any advice??

 

High output? or high capacity. High capacity=more amp/hours, high output=more VDC output.

There is no downside to using a higher cap battery, but it is a moot upgrade since the only thing it allows is for you to use the system longer before the battery drains.

 

I recommend a Optima Yellow top Deep Cycle battery, it is perfect for your car, I have one and is an awesome battery for cars with a lot of accesories to run.

 

I've had a yellow top optima for 2 years. I have a large system with Four 15' subs in a sub wall. I've drained the batter down dead a bunch of times. And it charges back up every time. Love it. You can also mount it anywhere since it is sealed. Just my opinion though.....

 

How much did you pay for it because I am looking into getting one. thanks
