Rechargeable Li-ion Battery everActive 16340 3.7V 700 mAh with micro USB

The everActive 16340 3.7V 700 mAh rechargeable Li-ion battery with integrated micro USB offers a compact, rechargeable power source for devices that accept 16340 cells. With a nominal voltage of 3.7V and 700 mAh capacity, this cell is designed for repeated charging cycles and convenient direct charging via the built-in micro USB port, removing the need for a separate charger. Its small form factor makes it suitable for portable lighting, cameras, and other compact electronics that require a high-energy-density cylindrical cell.

Advantages

The integrated micro USB connector enables on-the-go recharging without an external charger, simplifying maintenance and replacement. The Li-ion chemistry provides stable voltage and relatively high energy density for the cell size, allowing shorter weight and size compared with alkaline alternatives. Reusability reduces the frequency of single-use battery purchases and associated waste. The cell is compatible with devices that accept the 16340 format and benefits from standard handling practices for rechargeable lithium-ion cells.

Suitable for

• Compact flashlights and tactical lights that accept 16340 batteries
• Small digital cameras and camera accessories
• Portable electronic devices and LED modules designed for 3.7V 16340 cells
• Backup power for small sensors and wireless devices with matching cell dimensions
