A diagnosis very much depends upon what type of battery it is. What type of battery do you have under test?

The only thing to be sure is, to do a manual capacity test. The discharge rate depends on battery type. It is basically like, putting a defined load on a fully charged battery and measure the time until it reaches low voltage. A BMV can be very helpful to make this tests. Refer to the batteries datasheets, for discharge rates and voltages.
