Correct Battery and Cranking amps

When looking for a battery for say my car 69 camaro with a BB in it, should I be looking for a minimum amount of cranking amps?

What is the correct way to shop for a new battery.

Thanks

I did do a search for old posts but couldn't find anything

Re: Correct Battery and Cranking amps

As for size, it's a group 24 battery and for cold cranking amps (cca) I'd say nothing less than 700.

My battery of choice for the last 10+ years has been the Optima spiral cell red top. Yeah they're expensive but they seem to last and they hold a charge even when the car isn't driven for months at a time.

Re: Correct Battery and Cranking amps

Be carefull when buying a battery for older cars...make sure they are lead NOT calcium-calcium....The Ca batteries require a charge of about 14 to 14.2 volts, lead requires 13.8 to 14V
The Ca batteries never get a good charge, and die faster.
And if the US is like NZ, damn near all the guys behind the counter selling batteries dont even know this.

Same here and they don't puke acid all over your engine compartment like the wet cell batteries do.

Re: Correct Battery and Cranking amps

The advantage the Optima has it is less prone to vibration than the lead acid....that is why orginally our cars had a foam pad under them...and if you do have one, is it still foamy, and not hard?
I have never in 40 odd yrs had a lead acid spue acid out...
I have seen ppl tip them over, over fill and other abuse and seen it happen...

First, look into the battery manf's catalog to see what size is suggested for a starting point. Owner's Manual states, by CID, 12 volts, 61 plates, 2900 watts, at 0F cranking.

I would go with a 650-750 CCA battery.
