Moultrie Edge 10.8V 5000mAh Replacement Battery

Moultrie Edge Series — 10.8V Li-ion Replacement Battery (MMA-14109 / MMA-14128)

This is a 10.8V 5000mAh Li-ion battery for the Moultrie Edge, Edge 2, Edge 2 Pro, and Edge Pro trail cameras. It replaces OEM parts MMA-14109 and MMA-14128. At 54Wh, it carries enough capacity to keep the camera cycling through image capture, video bursts, and cellular transmission between field visits.

• Edge and Edge Pro compatibility: All four models in this lineup share the same 10.8V battery architecture, connector pinout, and BMS handshake protocol. Swapping between Edge and Edge Pro units requires no adapter or wiring change.
• Bench tested on actual hardware: We ran this battery through full charge and discharge cycles on an Edge 2 Pro. The BMS held voltage within spec across simulated cold and warm ambient temps, and the protection circuit tripped correctly at the low-voltage cutoff threshold without requiring a manual reset.
• Cold-weather field prep: Li-ion cells lose 15–25% usable capacity at 0°C and up to 40% at -20°C. Keep this battery in an inner pocket during transit to the field and install it just before mounting the camera — a warm cell going into a cold enclosure retains far more capacity than one that has been sitting in a frozen truck bed.

Why the Edge camera drains faster once overnight temperatures drop below freezing

Li-ion chemistry slows the electrochemical reaction at low temperatures, which directly reduces the number of electrons the cell can deliver per cycle. The Edge camera's cellular transmission bursts draw peak current, and a cold cell sags under that load more than a warm one does. The BMS reads the voltage sag as low charge and may trigger an early cutoff even when the cell still holds usable energy. Warming the battery to room temperature before deployment recovers most of that lost capacity — the chemistry hasn't degraded, it was just cold.

Camera won't boot after sitting unused through a cold season

If the Edge camera was stored outdoors or in an unheated space for several months, the battery may have self-discharged below the BMS minimum boot voltage — typically around 9V for a 10.8V Li-ion pack. The BMS locks the output rail at that threshold to prevent cell damage, so the camera gets no power at all. Bring the battery indoors and connect it to a charger; many chargers include a recovery or trickle mode that can bring a deeply discharged cell back above the re-enable threshold. If the charger shows a charge accepted and voltage climbs above 10V, the pack should recover and the camera will boot normally.
