Frequently Asked Questions

What is the difference between a momentary discharge and a sustained discharge?

The peak discharge current is the maximum current a battery can deliver for a short period of time—for the Keeppower IMR26650, it is 30A. The continuous discharge current is the current at which the battery can operate stably for a longer period—in this case, 15 A. If used beyond these values, the battery may be damaged or lose capacity.

Does the battery have built-in protection?

No, the Keeppower IMR26650 5500mAh is a battery without built-in protection. This means it should only be used in devices that have their own protection circuitry against overheating, overcharging, and deep discharge. Do not use unprotected batteries in unsuitable devices.

Why is the protruding tab important on flashlights?

For flashlights that use two or more batteries in series, the batteries must make contact with each other. The protruding positive terminal on the Keeppower IMR26650 ensures a reliable electrical connection between the cells arranged in series. A flat positive terminal in such cases can cause a break in the circuit.

Is this battery suitable for high-powered flashlights?

Yes. The Keeppower IMR26650, with a capacity of 5500 mAh and a maximum instantaneous discharge current of 30A, is designed specifically for devices with high current consumption, such as high-powered flashlights. The 26650 format is larger than the standard 18650 and offers higher capacity and a higher discharge current.

How do you charge a Keeppower IMR26650 battery?

The battery should be charged using a suitable charger that is compatible with the 26650 format and IMR chemistry. Since the cell has no built-in protection, the charger must have a charge control function to prevent overcharging. Use only high-quality chargers from reputable manufacturers.

What is the difference between the 26650 and 18650 formats?

The 26650 format is wider and longer than the 18650. The diameter of the 26650 is 26 mm, while that of the 18650 is 18 mm. Due to their larger volume, 26650 batteries typically offer higher capacity and a higher discharge current. They are not interchangeable—check your device’s specifications before use.

Where can I buy a Keeppower IMR26650 5500mAh battery?

You can find the Keeppower IMR26650 5500mAh battery at the Dulotec.COM online store, which specializes in selling high-quality flashlights, rechargeable batteries, and tactical equipment. The store offers trusted products from reputable brands.
