Voltage and AMPS
So I have a few cars on battery tenders. Now that winter is over I have checked the voltage. The batteries show 12.6 to 12.8 Volts. I just bought a battery tester. It too shows good voltage, but the CCA are in the 200 range and not 500. So it comes up with the message: REPLACE BATTERY. What do you think? I really don't want to waste my money on new batteries but I also don't want to be stuck at the side of the road. I only drive these cars above 40 degrees so CCA was of little concern, but should I be concerned? Thanks.
