Direct OEM Replacement

This sealed AGM battery is built as a 100 percent OEM replacement for the APC BACK-UPS ES BE550G unit. It arrives ready to install with no electrolyte handling required. The maintenance-free design means no water top-ups or specific-gravity checks during its service life.

Drop-In UPS Integration

The battery fits the existing compartment without modification and supplies the same voltage and connector layout as the original pack. Its non-spillable construction meets IATA transport rules so it can be shipped or moved in any orientation. Gas recombination exceeds 90 percent, reducing internal pressure build-up during normal float operation.

Long-Term Float Reliability

Expected service life spans four to seven years under typical float conditions. The sealed case and absorptive glass mat separators prevent electrolyte loss during extended charge cycles. A three-year warranty covers the UPS device itself while the battery carries a two-year warranty against defects.
