Standby Systems offers a wide range of batteries, including vented flat plate, Plante, and tubular technology cells. We also provide Valve Regulated Lead Acid (VRLA) batteries, often mistakenly referred to as sealed lead acid (SLA) or semi-sealed lead acid. Our selection includes lead-carbon VRLA for high-cycle applications, high-temperature and deep-cycle VRLA, and high-rate, long-life (HRL) VRLA for UPS use.
