Replacement for EnerSys NP2.3-12FR

This 12 V 2.3 Ah sealed lead-acid battery serves as a direct OEM replacement for the EnerSys NP2.3-12FR. It is built for standby power in UPS units, alarm panels and emergency lighting where a compact fire-retardant pack is required.

AGM design fits existing enclosures

Absorptive Glass Mat construction seals the electrolyte so the battery operates in any orientation without leakage. The non-spillable classification meets IATA transport rules and removes the need for water topping or gravity checks during its service life.

Gas recombination sustains float duty

A recombination rate above 90 % controls internal pressure during continuous float charging, supporting a 4 to 7 year design life. Maintenance-free operation means no periodic servicing is needed, making it suited for unattended backup installations.
