everActive EV26650-52M Rechargeable Battery 3.7V 5200mAh with Micro-USB charging function

Rechargeable everActive EV26650-52M is a 3.7V lithium 26650 cell with 5200mAh nominal capacity and an integrated Micro USB charging port. The cell is intended for applications that require a high-capacity rechargeable battery in the 26650 form factor, offering extended runtime and the convenience of direct charging via a Micro USB cable without the need for an external charger or special docking station.

Advantages

The built-in Micro USB charging interface simplifies replenishing the battery, reducing the need to remove cells for charging. High nominal capacity provides longer operating time compared with smaller formats, and the 26650 size delivers greater energy density per cell. The consistent 3.7V nominal voltage is compatible with equipment designed for single-cell lithium-ion operation. The cell is designed for repeated charge–discharge cycles and straightforward replacement in devices that accept standard 26650 dimensions.

Suitable for

• High-output flashlights and portable lighting
• Power banks and DIY battery packs for portable electronics
• Handheld tools and small appliances that accept 26650 cells
• Hobby electronics, RC projects and custom power solutions

Key specifications

• Cell type: lithium-ion rechargeable
• Nominal voltage: 3.7 V
• Nominal capacity: 5200 mAh
• Form factor: 26650 cylindrical cell
• Integrated charging: Micro USB port for on-cell charging
• Typical use: single-cell devices or multi-cell packs with appropriate battery management

How to use

Insert the 26650 cell into devices that accept the 26650 form factor, observing correct polarity. To charge the cell, connect a compatible Micro USB cable to the on-cell port and plug the other end into a USB power source rated for standard USB output. Monitor charging according to the device or convenient external charger indicators, and avoid charging from unknown or unstable power sources. For multi-cell assemblies, use appropriate holders and battery management systems to ensure balanced and safe operation.

Recommendations

Store and operate the battery within the temperature ranges specified by the device manufacturer. Do not expose the cell to mechanical damage, high temperatures, or water. Use the integrated Micro USB charging for routine recharging and follow general lithium-ion safety practices: avoid deep discharge, prevent short circuits, and recycle the battery according to local regulations.
