Description

The Duceri D001 is a 3.2V 1500mAh lithium iron phosphate (LiFePO4) replacement battery designed for Duceri emergency lighting fittings that use rechargeable LiFePO4 cells. The battery ships pre-wired with a white connector block that matches the socket inside compatible Duceri emergency light housings, allowing direct replacement without re-terminating cables.

Emergency lighting regulations require the backup battery to maintain sufficient capacity to power the fitting for the required duration (typically 3 hours) after mains failure. This replacement battery is specified to meet that requirement in Duceri LiFePO4-compatible emergency fittings. The battery recharges automatically when mains power is restored, cycling through charge and standby states as the fitting’s internal charging circuit dictates.

LiFePO4 chemistry offers a longer cycle life and greater thermal stability than older NiCd or NiMH emergency lighting b
