Sealed/Maintenance-Free The valve regulated, spill-proof construction of the Power-Sonic battery allows trouble-free, safe operation in any position. There is no need to add electrolyte, as gases generated during over-charge are recombined in …
Sulfation is a natural chemical process that occurs when lead sulfate crystals build up on the surface of a lead-acid battery''s electrodes during use. This buildup happens because the chemical reactions that produce electricity in the battery also produce lead sulfate crystals, which can accumulate over time.
