The Valve Regulated Lead Acid (VRLA) battery is one of many types of lead-acid batteries. In a VRLA battery the hydrogen and oxygen produced in the cells recombine back into water. In this way there is no leakage. Since VRLA batteries do not require (and make impossible) regular checking of the electrolyte level, they have been called Maintenance Free (MF) batteries.
Lead-Acid Battery Cells and Discharging. A lead-acid battery cell consists of a positive electrode made of lead dioxide (PbO 2) and a negative electrode made of porous metallic lead (Pb), both of which are immersed in a sulfuric acid (H 2 SO 4) water solution. This solution forms an electrolyte with free (H+ and SO42-) ions.

by the electrolysis of water from the aqueous solution of sulfuric acid. Since the water is lost, the electrolyte can be depleted. This is why you need to add water to "wet" (flooded type) non-sealed lead acid batteries.

Remember, when diluting acid never add water to the acid as this will react explosively. Always add acid to water. The concentration levels may be ascertained by measuring the specific gravity of the mixture. The right mixture should have a specific gravity of 1.26 to 1.28. You can add the diluted sulfuric acid to the battery if:

The biggest difference is that LiFePO 4 doesn''t like float charge as much as lead acid does. Well, to be exact, in UPS environments, lead acid batteries die in 5 years whereas in my car I already have 8 years on the battery and no signs of failure. I think the difference is that cars don''t do continuous float charge but UPS does.
