BatteryJack inc. PowerStar 6V 5AH UB645 UPS Replacement Battery for APC AP200

SKU CH-8X2J-EH8BY

6 V 5 Ah AGM battery replaces the APC AP200 UPS cell with sealed, maintenance-free construction and 90 % gas recombination

  • AGM technology prevents electrolyte leakage
  • 100 % OEM-compatible fit for APC AP200
  • Maintenance-free design needs no water or checks
  • Over 90 % gas recombination extends service life
  • Sealed non-spillable case allows any mounting position

Product Identity

The PowerStar UB645 is a 6V 5AH sealed lead-acid battery built as a direct replacement for the APC AP200 UPS unit. It uses AGM technology to deliver maintenance-free backup power for server and network equipment.

Build and Installation

Advanced AGM construction absorbs all electrolyte into glass-mat separators, preventing leaks and allowing operation in any orientation. The sealed, non-spillable case meets IATA air-transport requirements and eliminates the need for water top-ups or specific-gravity checks.

Practical Limits

Gas recombination handles over 90 percent of generated gas during normal float service, but the battery is not designed for deep-cycle applications or frequent full discharges. Expected floating life spans four to seven years, after which capacity will decline and replacement is required.

Highlights

  • AGM technology prevents electrolyte leakage
  • 100 % OEM-compatible fit for APC AP200
  • Maintenance-free design needs no water or checks
  • Over 90 % gas recombination extends service life
  • Sealed non-spillable case allows any mounting position
