I have a 6 to 7 year old battery that appears to be working normal. In the past I've just checked them with my voltage meter and waited until there were obvious signs the battery was failing to replace them.
However for peace of mind, I'm thinking about having a load test done on the battery since it might be good to know of it's condition (?) and wondered does this test do any permanent harm? Also I think it's best to remove the battery from the vehicle and take it to AutoZone or Advanced, etc. to have them do the load test - - is that correct or can it safely be tested while the battery is still installed in the car?
It is a side post battery and pretty hard to get to the terminals if that makes any difference. Do I need to know the load (e.g CCA) that they should use and the voltage number it should fall down to during the test?
