Stanilite 03-01307P Emergency Exit Light Replacement Battery 6.4V 3000mAh

Stanilite Platinum Exit LED Jumbo Nexus — 6.4V LiFePO4 Replacement Battery (03-01307P)

This is a 6.4V 3000mAh LiFePO4 replacement battery for the Stanilite Platinum Exit LED Jumbo Nexus emergency lighting unit. It fits models PEJLLXWM-1, PEJLLXWM-2, PEJLLXWM-3, and compatible variants sharing the same OEM part number 03-01307P. The cell sits inside the fitting and powers the LED exit sign during mains failure, keeping the unit active for its rated emergency duration.

• PEJLLXWM series compatibility: These models share the same 6.4V LiFePO4 cell format, connector, and charge controller float voltage. The BMS handshake is identical across the variant range, so one cell covers the full series without modification.
• Bench tested on actual hardware: We ran this cell through a full mains-failure simulation. The BMS accepted charge from the fitting's onboard controller without fault, held stable voltage under LED load, and recovered cleanly from a deep discharge state consistent with long-stored units.
• First test cycle after installation: Within 24 hours of fitting, hold the test button for the full rated emergency duration. This lets the charge controller register the new cell's capacity baseline before your next scheduled compliance test — skipping it risks a false short-duration reading.

Charge indicator staying red after new battery installation

The Platinum Exit LED Jumbo Nexus charge controller uses float voltage to confirm a healthy cell is present. A new LiFePO4 cell stored for several months will sit below the float acceptance window — typically under 6.0V resting — which the controller reads as a fault rather than a charge state. The controller will not switch to green until the cell voltage rises into the 6.4–6.6V acceptance band. Leave the fitting on mains power for 12–24 hours before concluding there is a wiring or controller fault.

Emergency light failing its duration test after battery replacement

A freshly installed cell that has not completed one full charge cycle will not deliver its rated 3000mAh capacity during a compliance duration test. LiFePO4 cells need at least one complete charge-discharge cycle to reach full electrochemical capacity — the charge controller cannot pre-condition this. If the fitting cuts out early during a test, restore mains power, allow a full 24-hour recharge, then re-run the test. The cell should hold rated load voltage above 5.5V for the full emergency period.
