BatteryJack inc. HIGH RATE 5AH 6V 4.5Ah SLA Battery

Replacement fit for UB645 and SLA640

This 6 V 4.5 Ah sealed lead-acid battery is a direct OEM replacement for models such as UB645, SLA640, APS46, LA640 and SLA4-6. It suits users who need a drop-in power source for UPS units, alarm panels or emergency lighting. Buyers who require a different voltage, capacity or form factor will not be served by this unit.

AGM chemistry limits and transport rating

The absorptive glass mat design recombines over 90 % of generated gas and is classified as non-spillable, meeting International Air Transport Association requirements. It can be operated in any position without electrolyte leakage, but it is not suited for deep-cycle applications that demand repeated full discharges.

Maintenance-free build with standard terminals

Sealed construction removes the need to check specific gravity or add water during the expected 4 to 7 year service life. The case prevents electrolyte escape from terminals or case walls, allowing safe mounting in any orientation. Users needing user-serviceable cells or alternative connector types should look elsewhere.
