BatteryJack inc. PS-6100 6V 12AH UPS Replacement Battery for Streamlight LIGHTBOX

Direct OEM Replacement

The BatteryJack PS-6100 is a 6V 12AH sealed lead-acid battery built as a 100% OEM replacement for the Streamlight LIGHTBOX. It uses advanced AGM technology with absorptive glass mat separators that hold electrolyte for steady service and a 4-7 year expected life. The maintenance-free design requires no water checks or specific gravity readings during its floating service life. It is classified as non-spillable for safe operation in any position.

Sealed Fit for UPS Units

The sealed construction prevents electrolyte leakage from terminals or case, allowing the battery to be mounted in any orientation the enclosure demands. Gas recombination handles over 90% of gas generated during normal use, so no venting provisions are needed inside the cabinet. This maintenance-free operation frees technicians from periodic service visits and eliminates the risk of acid damage to surrounding electronics. The non-spillable rating also satisfies air transport requirements for depot moves.

Steady Output Under Continuous Float

AGM separators keep electrolyte in constant contact with plates, delivering stable voltage throughout extended float periods rather than short bursts. Over 90% gas recombination limits internal pressure rise during long charging cycles, reducing dry-out risk that shortens lifespan. The sealed case maintains electrolyte integrity across temperature swings, so capacity remains consistent when the UPS must hold load for hours. Expected service life of 4-7 years reflects this sustained-load behaviour.
