28 vrla batteries immobilize the electrolyte.The active chemical leakage can then damage or disable the equipment that the batteries power.Physical component changes The active material on the battery plates changes chemical composition on each charge and discharge cycle; active material may be lost due to physical changes of volume, further limiting the number of times the battery can be recharged.

Deep cycle battery guide Archived 17 February 2009 at the Wayback Machine.66 Chemistry Many important cell properties, such as voltage, energy density, flammability, available cell constructions, operating temperature range and shelf life, are dictated by battery chemistry."Deep-cycle" leadacid batteries such as those used in electric golf carts have much thicker plates to extend longevity.
