Rechargeable battery everActive EV16340 700mAh 3V with Micro USB charging

Rechargeable everActive EV16340 700mAh 3V with Micro USB charging is a single-cell lithium battery in 16340 size that combines a nominal 3V output with an integrated Micro USB port for on-cell recharging. The cell provides 700mAh of capacity suitable for compact electronic devices where a single 3V cell is required and where charging convenience is important. The integrated charging interface removes the need for a dedicated external charger and is intended for low- to moderate-current recharges compatible with the battery chemistry and ratings.

Advantages

The battery’s built-in Micro USB charging port allows recharging directly from a USB power source without using an external charger, simplifying maintenance for portable equipment. Its 16340 form factor matches devices designed for this cell size, providing the standard 3V output expected by flashlights, sensors and small cameras. The 700mAh capacity offers a balance between compact dimensions and usable runtime, and the rechargeable lithium chemistry reduces single-use battery waste while enabling repeated cycling when recharged appropriately.

How to use

Install the battery in the device observing correct polarity. To recharge the cell, connect a Micro USB cable from a compatible 5 V USB power source (such as a USB wall adapter, power bank or computer USB port) to the port on the battery. Charging should be performed on a stable, protected power source and the battery should be removed from the host device if the device may interfere with charging. Follow the device manufacturer’s guidance regarding battery installation and any system-level charging limitations.

Recommendations

Use only USB power sources that provide stable 5 V output and avoid uncontrolled or high-current supplies. Do not leave the battery charging unattended for extended periods; monitor temperature during the first few charge cycles. Store and transport the battery according to standard lithium battery safety practices, avoiding short circuits and exposure to high temperatures. Replace the cell when capacity noticeably declines or if there are signs of damage.
