Hi,
I need a new battery since the one I have is 6 years old, and just died (bad cell), and won't recharge.

I was all set to get the cheapo $29.00 Walmart 510 cold cranking amps EverStart battery, when I noticed a battery catalog at Walmart said my car ( 88 GTA 5.7 TPI) was supposed to have a battery with 630 cold cranking amps.

The old battery had 650 cold cranking amps, btw.

Does it really matter if I get the 510 cold, versus the 630 cold ??

Will there be any performance difference?

Thanks,
GTA88

 

I would get what ever is recommended or larger.
Personally, I prefer the red top Optima dry cell batteries but they are about $100 more than you are looking to spend.

 

I got my Everstart Maxx (yellow) from Wal-Mart $60 or so, 1000 CCA.

 

Go with the highest cold cranking amps you can get, and still have a battery that will fit in the holder.

 

I think the power opts. u have the beter the battery u should get; I have pwr; trunk, windows, door locks ,ant. top line delco.

 

Thanks for the suggestions. I got the 630 cold cranking amps ( at zero degrees F ) from Walmart for $39. I took it to a parts store and had them test it, and it tested out at 901 cca at 75 degrees F. The car starts up a lot easier now.
