EluBat 275810 3.2V LiFePO4 Emergency Light Replacement Battery 3000mAh

EluBat 275810 — 3.2V LiFePO4 Replacement Battery (14-00-0002)

This is a 3.2V LiFePO4 cell rated at 3000mAh (9.6Wh), replacing OEM part 14-00-0002 in the EluBat 275810 emergency lighting unit. It fits the 275810 fitting directly and matches the original cell's dimensions at 66.60 × 37.00 × 18.60mm. LiFePO4 chemistry is standard in emergency lighting because the flat discharge curve keeps output voltage stable across the full backup duration.

• 275810 fitting compatibility: The EluBat 275810 uses a single-cell LiFePO4 configuration on a 3.2V charge rail. The OEM part 14-00-0002 spec locks the fitting to this exact voltage and footprint — swapping in a different chemistry or physical size will cause the charge controller to reject the cell or misread state of charge.
• Bench tested on actual hardware: We ran this cell through a full charge cycle and monitored the BMS handshake with the fitting's charge controller. The cell accepted charge from zero and held float voltage without triggering a fault LED.
• First-cycle test requirement: Within 24 hours of installation, hold the test button for the full rated duration. This lets the charge controller log the new cell's capacity baseline before any scheduled compliance test. Skipping this step means the controller may flag a duration fault even when the cell is healthy.

Charge indicator staying red after new battery installation

A replacement LiFePO4 cell shipped from storage typically arrives at a partial state of charge — often between 2.8V and 3.0V. Some EluBat charge controllers have a narrow float acceptance window and will hold a fault or red-charge state until the cell reaches approximately 3.2V to 3.3V. This is not a faulty cell — it is the controller waiting for the cell to clear its acceptance threshold. Leave the fitting connected to mains for at least 12 to 24 hours before concluding there is a problem.

Emergency light dims partway through a duration test

A new LiFePO4 cell does not always deliver full rated capacity on its very first discharge. The cell needs one complete charge-discharge cycle before the electrochemical structure stabilises and capacity reaches its rated 3000mAh. If the light dims or cuts out before the test period ends on first use, recharge fully and run the duration test again. After one full cycle the cell should hold output voltage without sag through the complete test window.
