A battery with or without protection?

Protected batteries contain a small circuit board embedded in the anode or cathode. It protects against overcharging, over-discharging, and excessive current—if necessary, it simply cuts off the power supply.

Batteries with a protruding positive terminal and built-in protection are suitable for flashlights with mechanical reverse-polarity protection—for example, those from Acebeam, Olight, Fenix, Nitecore, and Armytec. The G53 model has a flat positive terminal and does not have built-in protection.

Unprotected batteries are suitable for flashlights designed specifically for the standard size—including models from Dulotec and Zebralight. The protected versions are slightly longer and wider, which makes them incompatible with some devices.

Frequently Asked Questions

What is the difference between a battery with protection and one without?

A protected battery contains a built-in circuit board that protects the cell from overcharging, over-discharging, and excessive current. When dangerous levels are reached, it automatically cuts off the power supply. An unprotected battery, such as the Vapcell G53, relies on the device’s own protective mechanisms. It is more compact and suitable for flashlights designed for standard sizes and higher current ratings.

Is the Vapcell G53 battery compatible with my flashlight?

The Vapcell G53 is a flat-top 26650 battery with a diameter of 26.6 mm and a height of 65.2 mm. Before purchasing, measure the size of the battery used in your flashlight and compare it to these dimensions. If you’re unsure, contact us and we’ll help you choose the right battery.

What charger should I use to charge the Vapcell G53 battery?

Use a high-quality charger designed for lithium-ion batteries. Normal charging is at 2000 mA, and fast charging is at 3000 mA. The voltage at the end of charging is 4.20 V. Do not charge at sub-zero temperatures, and do not use unsuitable or defective chargers.

At what temperatures can I use and store the battery?

Filling is permitted at temperatures between 0°C and 45°C. Dilution may be performed within a range of -20°C to 75°C. A storage temperature between -5°C and 35°C is recommended. Avoid humid environments and direct sunlight during storage.

How do I store the battery safely?

The battery must be stored in a special protective case—never in a pocket or bag along with metal objects, as this can cause a short circuit. If the battery has not been used for more than 3 months, charge it before use. Do not store at temperatures outside the recommended range.

Which brands of flashlights are compatible with batteries that have built-in protection and a raised positive terminal?

Batteries with a protruding positive terminal and built-in protection are suitable for flashlights with mechanical reverse-polarity protection. These include models from Acebeam, Olight, Fenix, Nitecore, and Armytec. Dulotec and Zebralight flashlights are designed for standard-size batteries without protection—which is why the Vapcell G53 with a flat positive terminal is a suitable option for them.

What should I do if the battery wrap is damaged?

Do not use a battery with a damaged protective film. A damaged coating may cause contact between the cells or with metal surfaces, resulting in a hazardous situation. In such a case, contact us for assistance or dispose of the battery in accordance with the guidelines for lithium-ion cells.
