[quote=”automechanic” post=56716]voltage: 12.56v
measured: 624 cca
rated: 700 cca
temp 77 F[/quote]The voltage reading is fine for a charged battery. (I assume that reading is without the vehicle running. If it’s running, check the charging system, the reading is too low.)
The measured CCA is 89% of rated CCA. That’s OK for now by itself, you need more info. Find out what the manufacturer states is the CCA needed for your vehicle. If measured CCA is less than needed, replace the battery. If not, you won’t need to replace it right away, you’ll just need to keep an eye on it. For example; vehicle needs 560 CCA. That battery will work for now. Vehicle needs 650 CCA. Battery doesn’t have quite enough amps to start the vehicle easily, replace it.
here is the reading with it running
ok replace soon

14.59vthis is the test results
For now the battery is ok. I had the same scenario that my
battery voltage was on the money.But my cca was low. The battery
did start the truck. I ended getting a new battery for the sake of
not getting stranded or over working my alternator. I believe it was
$75.00 bucks. 🙂[quote=”automechanic” post=56767]here is the reading with it running ….

Ok, charging system voltage is good. Cranking voltage is a hair low, but if vehicle starts in 1.09 seconds, the battery is powerful enough. So it sounds as if you probably don’t need to replace it right now, but may need to in late fall. (in my opinion, your mileage may vary 😉 )[quote=”automechanic” post=56800]what should the cranking volts and the cca be be for my 1995 chevy s10[/quote]
Cranking volts should be at least 9 volts, and I like to see over 10.5. My reference says the OE battery was group size 75: OE CCA rating 525. A OE battery with a CCA rating of 690 was optional.
This may help
