The Keeppower P1826RC is a high-performance protected 18650 rechargeable Li-ion battery designed for devices that require a reliable combination of power output, capacity, and built-in safety protection.

With a 2600mAh typical capacity and 3.7V nominal voltage, the P1826RC delivers dependable rechargeable power for compatible high-drain devices. It supports up to 15A maximum continuous discharge current, making it well suited for applications that demand more current than standard protected 18650 batteries.

High-Drain Performance

Unlike many conventional protected 18650 cells designed primarily for capacity, the P1826RC is built to handle higher current demands. Its 15A maximum continuous discharge capability provides stable power for compatible high-performance flashlights and other demanding electronics.

Built-In Protection Circuit

The integrated safety circuitry provides protection against:

• Overcharging

• Over-discharging

• Over-current

• Short circuits

This added protection makes the P1826RC a practical choice for users who want the performance of a high-drain 18650 battery with an additional layer of electronic protection.

Rechargeable & Long Lasting

The P1826RC is designed for 500+ charge-discharge cycles under appropriate operating conditions, providing a reusable alternative to disposable batteries.
