BatteryJack inc. UB12100-S D5719 12V 12Ah battery

Universal 12 V power replacement

This sealed 12 V battery uses advanced AGM technology to deliver reliable backup power for UPS units, alarm panels and portable equipment. The absorptive glass-mat design prevents electrolyte leakage and allows safe operation in any orientation. It is classified as non-spillable and meets International Air Transport Association requirements for transport.

12 Ah capacity at 12 volts

The single specification that determines fit is the 12 Ah rating at 12 V, matching the UB12100-S D5719 form factor used in many OEM devices. This capacity dictates how long the unit can sustain a load before recharge is required. Verify the amp-hour rating against your equipment label before purchase.

Gas recombination handles sustained float duty

Over 90 % of gas generated during normal operation is recombined internally, so the battery remains maintenance-free throughout its 4-7 year expected float life. No water top-ups or specific-gravity checks are needed, and there is no provision for such service. The sealed construction maintains steady performance during continuous standby or cyclic use.
