Pelican 7610 Tactical Flashlight Replacement Battery 3.7V 3400mAh

Pelican 7610 / 7620 / 5050R / 2380R Tactical Flashlight — 3.7V Li-ion Replacement Battery (02380R-3010-000E)

This is a 3.7V 3400mAh Li-ion cell that replaces the original battery in the Pelican 7610 and 7620 Tactical Flashlights, 5050R, 2380R, and compatible models. It matches the OEM dimensions of 70.80 × 18.70 × 18.60mm and slots directly into the flashlight's battery compartment. Voltage and capacity match the original spec so the driver board sees no difference at startup.

• 7610 / 7620 / 5050R / 2380R platform fit: These models share the same cylindrical cell format, voltage rail, and driver board threshold. A single cell spec covers the full group without modification.
• Bench tested on actual hardware: We ran this cell through charge-discharge cycles on the 7610 platform and monitored BMS cutoff behaviour at both high-draw turbo mode and standard output. The protection circuit tripped cleanly at the expected low-voltage floor with no false cutoffs at full draw.
• Turbo mode draw management: The 7610 driver pulls significantly more current in turbo mode than in standard or low. If you run turbo continuously, the cell voltage drops faster than the battery indicator updates — step down to high or standard for sustained use to keep the cell within its stable discharge window.

Why the 7610 dims before the battery indicator hits low

The 7610 driver uses a brownout protection threshold that kicks in before the battery indicator registers empty. When cell voltage drops below roughly 3.0V under load, the driver steps output down rather than cutting off entirely — this is intentional. The indicator reads resting voltage, not loaded voltage, so there's a gap. You'll see the beam step down while the indicator still shows partial charge. That's the driver protecting the cell, not a fault with the battery.

Flashlight flickering or cycling through modes near end of charge

Mode cycling near the end of a discharge cycle means the driver is losing voltage stability — the cell drops below the driver's minimum input, recovers slightly, then drops again. This creates a rapid on-off or mode-switch loop. It's not a cell defect; it's the driver oscillating at the edge of its operating threshold. Switch to a lower mode immediately or power the light off and charge the cell — load voltage at this point is typically sitting at or below 3.0V, and pushing it further shortens cell lifespan.
