3.7V Rechargeable CR2-Size Lithium Cells, Two or Four

Replace a compatible rechargeable CR2-size cell with a 3.7V lithium-ion battery. It is for users whose equipment explicitly accepts this voltage and chemistry.

• ✅ Replace a matching cell — Choose only for a device specified for rechargeable 3.7V operation.
• ✅ Recharge for reuse — Use a charger compatible with the lithium-ion cell.
• ✅ Choose the quantity — Two- and four-cell packages are available.
• ✅ Check the physical fit — Published dimensions help compare the battery compartment.

Match voltage, chemistry and size together

A rechargeable 3.7V cell is not automatically interchangeable with a disposable 3V CR2. Confirm the equipment's battery requirements before purchase.

The packages contain batteries only. Keep cells away from children and use the correct polarity and charging system.
