A battery with or without protection?

Protected batteries have a built-in circuit board that protects the cell from overcharging, over-discharging, and excessive current. If a problem occurs, the protection mechanism is triggered and shuts down the battery.

It is important to note that protected batteries are slightly longer and wider than standard ones. They are not suitable for all flashlights—some devices are designed for the standard size or require a higher current.

Compatible with flashlights featuring mechanical reverse-insertion protection: Acebeam, Olight, Fenix, Nitecore, Armytec
They are not suitable for flashlights such as Zebralight and Dulotec flashlights, which are designed for unprotected batteries
Before purchasing, measure the size of the original battery in mm and compare it with the technical specifications

Instructions for Use

Frequently Asked Questions

What is the difference between a battery with a raised positive terminal and one with a flat positive terminal?

Batteries with a protruding positive terminal make physical contact with the springs and contacts in flashlights equipped with mechanical reverse-insertion protection. The flat positive terminal is used in devices where contact is made directly on a flat surface. The Vapcell 26650 5500mAh 20A battery has a protruding positive terminal and is suitable for flashlights such as Acebeam, Olight, Fenix, Nitecore, and Armytec.

Is this battery compatible with Dulotec or Zebralight flashlights?

Dulotec and Zebralight flashlights are designed for batteries without a protection circuit. The Vapcell 26650 5500mAh 20A battery does not have a protection circuit, so you must verify that its exact dimensions match the specific flashlight model. We recommend measuring the original battery and comparing it to the specified dimensions: 26.6 mm in diameter and 65.2 mm in height.

What charger should I use for a Vapcell 26650 battery?

Use a high-quality charger designed for lithium-ion batteries. The normal charging current for this cell is 2000 mA, and up to 3000 mA for fast charging. Do not exceed a voltage of 4.20 V during charging. Avoid cheap and untested chargers.

How do I store the battery properly?

The battery should be stored at a temperature between -5°C and 35°C. Do not leave it in a pocket or bag without protection—always use a special protective case. If the battery has not been used for more than 3 months, charge it before use. Keep it away from moisture, fire, and direct sunlight.

What is the difference between rated capacity and minimum capacity?

The battery's rated capacity is 5,500 mAh, which is the typical value under normal discharge conditions. The minimum capacity is 5,400 mAh, which is the guaranteed lower limit provided by the battery. The difference between the two values is small and demonstrates the stability of the manufacturing process.

What is the operating temperature of the Vapcell 26650 battery?

During charging, the battery operates within a range of 0°C to 45°C. During discharge, the range is significantly wider—from -20°C to 75°C. Do not charge the battery at sub-zero temperatures, as this may damage it. When storing the battery, keep it within a temperature range of -5°C to 35°C.

How can I figure out which battery is right for my flashlight?

The most reliable way is to measure the flashlight's original battery in millimeters and compare it to the technical specifications of the new battery. For the Vapcell 26650 battery, the diameter is 26.6 mm and the height is 65.2 mm.
