Its rechargeable chemistry allows repeated charge and discharge cycles, reducing the need for disposable batteries. The 3.7 V nominal voltage is compatible with a wide range of small electronics and single-cell devices. As a generic product, it is readily available and can be used as a practical spare cell.

Suitable for

• Handheld flashlights and torches that accept single 3.7 V cylindrical Li-ion cells
• Portable audio devices and small electronic gadgets designed for single-cell operation
• Battery replacement in hobby electronics, DIY projects, and prototype devices
• Backup or spare cell for devices where original branded cells are not mandatory

Key specifications

• Cell type: Rechargeable lithium-ion (Li-ion) cylindrical cell
• Nominal voltage: 3.7 V
• Rated capacity: 3000 mAh
• Form factor: Single cylindrical cell suitable for devices compatible with this size and voltage
• Intended use: Replacement or spare for single-cell 3.7 V devices

How to use

Insert the battery into the device following the device manufacturer’s polarity markings and orientation. Charge the battery only with chargers designed for single-cell 3.7 V Li-ion batteries and follow the charger manufacturer’s instructions. Do not force the cell into incompatible compartments or adapters. Monitor the battery temperature during initial use; discontinue use if the cell becomes unusually hot or shows signs of damage. For long-term storage, partially charge the cell to around 40–60% and store in a cool, dry place.

Usage recommendations

Observe safe charging and handling practices: use an appropriate Li-ion charger with proper voltage and current limits, avoid deep discharges, protect the cell from mechanical damage, and keep it away from high temperatures and moisture. Replace the cell if it shows swelling, leakage, or significant capacity loss. Dispose of used cells according to local battery recycling regulations.
