Lead-acid batteries should never be allowed to remain for a long period in a discharged state because lead sulfate could harden and permanently clog the pores of the electrodes. Before storing it for a long time the battery should be completely charged, then the electrolyte should be drained so that the battery is stored dry.
The leading health indicator of a battery is capacity, a measurement that represents energy storage. A new battery should deliver 100 percent of the rated capacity. This means a 5Ah pack should deliver five amperes for 1 hour. If the battery quits after 30

The capacity of a lead-acid battery is measured in ampere-hours (Ah) and indicates how much current the battery can supply over a certain period of time. It''s important to note that the capacity of a battery decreases over time, and the rate of decrease is affected by factors such as temperature, depth of discharge, and charging/discharging rates.

Valve regulated lead acid (VRLA) batteries are similar in concept to sealed lead acid (SLA) batteries except that the valves are expected to release some hydrogen near full charge. SLA or VRLA batteries typically have additional design features such as the use of gelled electrolytes and the use of lead calcium plates to keep the evolution of hydrogen gas to a minimum.
