BatteryJack inc. 6V 5AH SLA Standard Battery ub645

SKU CH-5D1A-V2H2H

A 6 V, 5 Ah sealed lead-acid battery with AGM technology for maintenance-free standby power

  • Maintenance-free design with sealed AGM construction
  • 100% OEM replacement for ub645 and compatible models
  • Over 90% gas recombination for safe operation
  • Position-free installation in any orientation
  • Expected service life of 4-7 years

What it is and who it serves

This 6 V 5 Ah sealed lead-acid battery replaces ub645 bp4-6 np4-6 wp4-6 sb604b models in UPS units and backup devices. It fits any equipment requiring that exact voltage and capacity combination.

Sustained-load behaviour

Absorptive Glass Mat technology absorbs electrolyte into glass-fibre separators for steady service and the longest life. Gas recombination handles over 90 of generated gas during normal use so output remains stable over extended discharge periods.

Build quality and connectors

Sealed construction prevents electrolyte leakage from terminals or case in any mounting position. The non-spillable classification meets International Air Transport Association requirements. Maintenance-free design needs no water or specific-gravity checks for the 4-7 year expected floating life.
