What is the shelf life of the VRLA battery and how to maintain the battery?

The limiting factor of the battery's shelf life is the rate of self-discharge which itself is temperature-dependent.

VRLA batteries will self-discharge less than 3% per month at 77°(25℃), VRLA batteries should not be

stored for more than 6 months at 77°(25℃), without recharging.  If in hot temperature, recharge it every 3

month. When batteries are taken out of long storage, it is recommended to recharge before use.

Why battery has different capacity at different hour rate?

The capacity of a battery in Ahs is a dynamic number that is dependent on the discharge current. For

example, a battery that is discharged at 10A will give you more capacity than a battery that is

discharged at 100A. With the 20-hr rate, the battery is able to deliver more Ahs than with the

2-hr rate because the 20-hr rate uses a lower discharge current than the 2-hr rate.
