  • Reliable 3.7V output keeps compatible devices running at optimal levels
  • 2600mAh capacity delivers extended runtime for power-hungry gear
  • Rechargeable design saves money and cuts waste versus disposable cells
  • Compact 2.6 x .7 inch form fits tight spaces without adding bulk
  • Light 1.6oz weight makes it easy to carry as a spare power source

Power and capacity

This Pelican 18650 rechargeable lithium-ion battery delivers a 2600mAh capacity at 3.7V for 9.6Wh of energy. It fits any device that accepts standard 18650 cells and suits users who want a reusable power source for compatible flashlights, lanterns or other gear. The rechargeable design reduces waste and ongoing cost compared with disposable alternatives. Buyers who need a different form factor or higher capacity should look elsewhere.

Thermal and electrical behaviour

The cell provides a consistent 3.7V output during normal operation. No thermal, noise or power-draw specifications are supplied for typical use, so no further detail can be given. Users should follow the device manufacturer's guidelines for charging and operating temperature limits.

Physical format and daily handling

The battery measures 2.6 by .7 inches and weighs 1.6oz, making it compact and lightweight for everyday carry. Its standard 18650 dimensions mean it slides into existing battery compartments without adapters. The rechargeable construction allows repeated cycling, so the same cell stays in service instead of being replaced after each use.

Questions about this item

How do I install the Pelican 18650 2600mAh battery, and what orientation mistake should I avoid?

Insert the cell with the positive button facing the device's marked + contact; the 18650 form factor fits only one way, so forcing it backwards damages the spring or the 3.7V cell.

What maintenance or replacement will this 2600mAh lithium-ion cell need over time?

Expect gradual capacity fade after several hundred charge cycles; when run-time drops below useful levels, replace the entire 18650 cell — no user-serviceable parts inside.

What limit appears first during sustained high-drain use of this 9.6Wh battery?

Voltage sag under heavy load hits first; the 3.7V nominal output drops toward the device's cut-off threshold, ending usable run-time before the 2600mAh rating is fully delivered.
