UPS Replacement Battery

The BatteryJack UB645 is a 6V 4.5Ah sealed lead-acid unit built as a direct OEM replacement for compatible uninterruptible power supplies and alarm systems. It uses AGM technology for maintenance-free operation and a sealed, non-spillable design that meets IATA transport requirements.

Build Integration

The battery fits into existing UPS chassis or alarm panels that accept the UB645 form factor, requiring no wiring changes or additional hardware. Its position-free construction allows installation in any orientation, freeing layout options inside tight server racks or wall-mounted enclosures.

Sustained Load Behaviour

The AGM system absorbs electrolyte in glass-mat separators to deliver steady service and a 4-7 year expected floating life. Gas recombination handles over 90 percent of generated gas during normal use, so the cell maintains voltage without watering or specific-gravity checks throughout its service interval.

Highlights

  • Maintenance-free operation with AGM technology
  • Over 90% gas recombination for safety
  • Sealed non-spillable design for any position
  • 100% OEM replacement fits UB645 models
  • Expected 4-7 year service life

Questions about this item

How long can the battery maintain its rated 4.5Ah capacity before the 4-to-7-year service life ends?

The sealed lead-acid cell is designed for a floating service life of 4 to 7 years, and the AGM construction prevents electrolyte loss so the 4.5Ah rating remains stable throughout that period.

Does the AGM design keep the unit cool and quiet during continuous float charging?

The gas-recombination system recovers over 90% of generated gas, eliminating venting noise and keeping the case temperature low during uninterrupted float operation.

What existing UPS or alarm panel connector does the UB645 need to slot into?

The UB645 uses the standard 6 V SLA form factor with F1/F2 faston tabs, so it drops directly into any UPS or alarm panel built for a 645-size 6 V battery.
