well, my autozone battery has 620 cold cranking amps, but if i turn the key more than 3 times in a row, the battery is DRAINED!!

what's going on here? i have a brand new starter and new alternator.

when the car warms up, it feels like it needs more juice for the car to turn on...
could the heat be destroying the battery power?

and also, is my compression a factor in this?

 

525 is the minimum suggested cranking amps for a stock engine and with your 11.9:1 compression it'll take more. Why did you buy the cheapest battery from Autozone? I would get a 700 crank amp or more battery.

 

i realized your point later on, and bought a 750 cca, and that helped quite a bit... live in learn, i guess...

 

I just bought a 1000 CCA and 875 regular. OMG...it turns over like a ****. Its great. Even hot starts are a breeze. I love it. The more the merrier

 

1000?????


great googly-moogly!! i must confess--i was looking for more amps, but 750 was the highest i could find...

how much did it cost ya?

 

a high torque starter would be a really good idea for an engine with practically 12:1 the higher torque starters are more efficient than stock and with their higher gear multiplication they make more turny turny with less pull on the battery and a higher amp battery always helps as does bigger wires going between them, and clean grounds, and so on. hope this helps

WALMART!!!!! I love Walmart I've bought a bunch of batteries and car stuff there for friends and my cars and not a single problem. (Sorry for the rant) It was like $70.00 or 80. I think 70, but its the MAXX-1N. Its even nice looking w/ yellow body and black top. It is a little heavier and wider. If you break off the lip on the outside edge of the battery tray (really easy) and ever so slightly bend up the hood support ( can easily be readjusted by spinning stopper). It fits fine. Someone brought up the idea of relocating to the back for traction. Thats also an option. Take that battery you got back and get this one if you want. I am not kidding, my car starts almost instantly. Maybe 1 second of turning over. Crank Crank, vroom. Especially with you higher compression you need it.
