How can I maximize performance of my battery?

Answer
Most manufacturers say that Valve Regulated Lead Acid (VRLA) batteries should always be charged. The typical shelf life of a VRLA battery is up to 1 year however batteries should be recharged after 6 months if not in use. Keeping your batteries in a cool and dry place while not in use will help maximize your batteries performance.

If you have a lot of moisture around your battery, it can potentially corrode contact points and limit charge-discharge performance.
