"How do I know when it is time to replace my battery?
Perform a capacity test. Short duration load tests and impedance/conductance measurements are not reliable to determine the actual capacity of a battery".
I covered capacity testing at least a dozen times, I might as well as written a dissertation about nuclear pile emitter exchanging.
Concorde is absolutely correct because a wild majority of their products are used for long-term storage. Should I have written once again how to adquire, connect and use a variable amp hour tester? It involves the use of 12 volt light bulbs to ballast a load to specification then timer to tell when to disconnect then measure total amp hours capacity.
AGM batteries that deteriorate because of charging abuse or storage abuse will absolutely reflect it in compromised CCA.
Concorde is so sensitive about exactness they argue the point of a five one hundredths of volt maintenance float charge. Again that is inarguably correct. God bless them they are one of the few ignorant or information suppressed battery manufacturers.
I have raised eyebrows if you should own an absorbed glass mat battery if you would assemble and use a recommended battery capacity meter that follows their specifications. Leave it all to guesswork? Ouija board? Or use a carbon pile load tester.
Or demand exact capacity testing.
