3.7 V 18650 Rechargeable Li-Ion Cell

Replace a correctly matched cell or power a suitable electronics project with a rechargeable 18650 lithium-ion battery. This range offers nominal 3.7V cells in several capacity-labelled selections.

✅ Power equipment designed for this cell format - A compatible 18650 device or project can use the cell once the size, terminal and electrical requirements match.

✅ Recharge for the next use - The lithium-ion cell is rechargeable with a suitable matched charger instead of being a disposable battery.

Match the Unprotected Cell to the Device

These cells are specified without a protection PCB. Use only equipment and charging arrangements designed for that cell type, and confirm the actual discharge-current requirement before choosing the cell; a capacity label does not establish a safe current rating.

Check the terminal style and dimensions as well as the 18650 name. This is a 3.7V lithium-ion cell, not an AA replacement. Keep the terminals protected from short circuits during storage and handling, and follow the matched device and charger instructions.
