BatteryJack inc. UB1213 12V 1.3AH Standard Battery

Direct replacement for UPS and backup units

The UB1213 is a 12 V 1.3 Ah sealed lead-acid battery built with absorptive glass mat technology. It fits devices that specify the UB1213, SLA1005, NP1.2-12, BP1.2-12 or WP1.2-12 part numbers. The maintenance-free design allows installation in any orientation without electrolyte leakage. Expected service life ranges from four to seven years under normal float conditions.

Fits existing battery compartments without

The sealed construction meets non-spillable classification for safe transport and operation in any position. Gas recombination exceeds ninety percent during normal use, eliminating the need for water top-ups or specific gravity checks. The unit drops into the same footprint as the models it replaces, freeing the builder from chassis changes or additional mounting hardware. No provision for routine maintenance is required or provided.

Upgrades ageing 1.2 Ah cells to 1.3 Ah capacity

Replacing a 1.2 Ah battery with this 1.3 Ah unit adds a modest runtime increase while keeping voltage and form factor identical. The jump is worthwhile when the original pack reaches the end of its four-to-seven-year design life or shows reduced backup time. Buyers who need significantly longer runtime or a different voltage should look elsewhere, as this model only covers the listed 12 V 1.3 Ah replacements.
