BatteryJack 6V 4.5AH SLA UPS Battery

This pack contains two sealed lead-acid batteries built with absorptive glass mat technology. They serve as direct replacements for compatible uninterruptible power supplies and backup devices. The maintenance-free design uses a sealed construction that prevents electrolyte leakage in any mounting position. Gas recombination exceeds 90 percent during normal operation.

Check voltage and capacity before ordering

Verify that your UPS or backup unit requires a 6 volt 4.5 ampere-hour battery with the same physical footprint. Confirm the terminal layout matches the original UB645, BP4-6, NP4-6, WP4-6 or SB604B part numbers. Ensure the charging circuit is designed for sealed AGM chemistry. These units are not suitable for systems needing a different voltage or capacity.

Sealed AGM design runs without venting

The absorptive glass mat separator holds electrolyte securely, eliminating spill risk and allowing operation in any orientation. Gas recombination keeps internal pressure low without external venting during typical float service. Expected service life ranges from four to seven years under standard conditions. No watering or specific gravity checks are required throughout the battery's lifespan.

Questions about this item

Does the 2PK include both batteries and any cables or hardware?

The 2PK supplies two 6V 4.5AH sealed lead-acid batteries. No cables, mounting brackets or additional hardware are included.

When should I choose the 4.5AH version over a higher-capacity alternative?

Select the 4.5AH model when your UPS specifies a 4.5AH 6V battery such as UB645, BP4-6, NP4-6, WP4-6 or SB604B.

What does the 90% gas-recombination figure mean for daily UPS operation?

Over 90% of gas generated during normal charging is recombined internally, so the battery stays maintenance-free and can be mounted in any orientation.
