Keeppower 18500-E260 2600mAh 3.6V Li-ion Rechargeable Battery Cell

The Keeppower 18500-E260 is a high-capacity rechargeable lithium-ion battery designed for compatible devices that use the compact 18500 battery format. With a 2600mAh nominal capacity and 3.6V nominal voltage, it provides a practical balance of compact size, reliable runtime, and rechargeable performance.

Its 18mm diameter and approximately 49mm length make it shorter than a standard 18650 cell, making it suitable for compatible flashlights and other electronic devices specifically designed for 18500 Li-ion batteries.

2600mAh High Capacity

With a 2600mAh nominal capacity and a minimum rated capacity of 2520mAh, the Keeppower 18500-E260 is optimized for applications where runtime and energy capacity are more important than extremely high discharge output.

It provides dependable rechargeable power for compatible low- to moderate-drain devices.

2.6A Continuous Discharge

The 18500-E260 supports a maximum continuous discharge current of 2.6A, with a maximum pulse/peak discharge current of 5A.

This makes the cell suitable for compatible devices operating within its specified discharge limits.

Rechargeable Li-ion Chemistry

The battery uses standard CC-CV charging with a maximum charging voltage of 4.20V.

A standard charging current of 520mA is recommended, with a specified standard charging time of approximately 360 minutes.

For safe and reliable operation, always use a quality Li-ion charger compatible with 18500 cells.

Compact 18500 Size

Measuring up to approximately 18.3 mm in diameter and 49.2 mm in length, the 18500-E260 offers useful capacity in a shorter format than conventional 18650 cells.

Always check your device's battery requirements and physical dimensions before purchasing, as 18500 batteries are not interchangeable with every 18mm Li-ion battery format.
