Pelican 7610 Tactical Flashlight Replacement Battery 3.7V 2600mAh

Pelican 7610 Tactical Flashlight — 3.7V Li-ion Replacement Battery (02380R-3010-000E)

This 3.7V Li-ion cell delivers 2600mAh to Pelican's 7610 Tactical Flashlight and several related models in the same flashlight family. It slots in as a direct cell replacement for field personnel who cycle these lights hard through shifts. Voltage and form factor match the original spec exactly — 70.80 × 18.70 × 18.60mm.

• 7610, 7620, 5050R, and 2380R compatibility: These models share the same single-cell 18650-format bay, 3.7V nominal rail, and driver circuit voltage window — one cell part number covers all of them without modification.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the 7610 driver board. The BMS held cutoff at 2.75V under load and accepted a full charge to 4.2V without triggering protection flags.
• Single-cell replacement tip: The 7610 runs one cell, so there is no multi-cell balancing concern — but if you carry a spare, rotate both cells on the same charge schedule. A deeply discharged backup cell dropped into a warm driver can trip the BMS on first draw.

Turbo mode current draw and what it does to cell voltage

The 7610's turbo mode pulls significantly more current than standard or low modes — the driver demands a burst that can drag cell voltage down fast under sustained use. When cell voltage sags below the driver's brownout threshold, the light steps itself down automatically. This is not a fault — it is the driver protecting the LED and the cell from running at damaging voltage levels. If turbo endurance matters operationally, a fresh cell at full charge gives the longest window before sag triggers the step-down.

Flashlight dims noticeably before the low-battery indicator activates

The 7610 driver steps down output when cell voltage drops under load, and this happens before the voltage reading at rest triggers the low-battery indicator. Under high-current draw, terminal voltage sags lower than the resting voltage the indicator samples. The gap between those two readings means the light dims first and the indicator catches up later. If you see step-down dimming during use, check resting cell voltage — anything below 3.5V warrants a swap before the next deployment.
