3.7V Rechargeable Batteries: 18650, 21700, 26650

3.7V rechargeable lithium-ion cells for flashlights, torches and other devices that take loose batteries. The range covers 18650, 21700, 26650 and 2D sizes from KLARUS, WUBEN, XTAR, LIITOKALA, PEETPEN and 1kon, with capacities from 1800mAh to 5200mAh and prices from KSh 600 to KSh 3,000.

When choosing, compare the size your device takes, the capacity in mAh for longer run time, and whether the cell is protected or flat top. Discharge rating matters for high-drain lights, and built-in USB-C charging on some XTAR cells saves carrying a separate charger.

• Match the cell size and top style to your torch or charger
• Pick higher mAh for longer run time
• Check the discharge rating for high-drain devices
• Protected cells add safety circuitry; check they fit
