What parameters are used in analyzing battery performance?

Intercell resistance. To check the conduction path integrity and avoid possible fires and abrupt shutdowns. Load cycles. To check the number and depth of discharges. This information is used to project battery life and settle warranty issues. Other parameters that are useful in analyzing battery performance are: Load current.

How do you test a deep cycle battery?

Deep Cycle batteries are often tested with discharge testers, a simple procedure. The tester discharges the battery through a pre-set current (Amps) till it reaches a disconnect voltage. Test time is the major issue with this kind of testing. Ex: Testing a 100 Ah battery at 5 Amps could take 20 hours. What is Cold Cranking Amp (CCA)?
