A battery with or without protection?

Protected batteries have a small circuit board built into the anode or cathode. It protects the cell from overcharging, over-discharging, and excessive current—if necessary, the protection circuit cuts off the power.

Batteries with protection have a protruding positive terminal and are suitable for flashlights with mechanical reverse-polarity protection—for example, models from Acebeam, Olight, Fenix, Nitecore, Armytec, and similar brands.

Unprotected batteries are more compact and can deliver a higher current. They are required for devices designed for a standard size—such as Zebralight and Dulotec flashlights, which do not support protected cells.

Protected batteries are slightly longer and wider than standard ones, so they are not compatible with all flashlights. The most reliable way to choose the right one is to measure the original battery in millimeters and compare those measurements to the specifications of the new one.

Safety Rules for Use and Storage

Improper use may cause a fire or explosion. Follow these rules:

Do not modify, disassemble, puncture, cut, crush, or short-circuit the battery.
Do not expose to water, fire, or high temperatures.
Do not use in defective devices.
Do not throw into a fire.
Do not overcharge, do not undercharge, and do not charge at sub-zero temperatures.
Do not use the battery if the foil is damaged.
Do not store in a pocket or purse—use a protective case.

Frequently Asked Questions

What is the difference between a 16340 battery and a CR123A?

The 16340 format is a rechargeable version with nearly the same dimensions as the disposable CR123A. The dimensions of the Vapcell 16340 T8 are 16.4 x 34.0 mm. The CR123A is a disposable battery and cannot be recharged. Before inserting a rechargeable 16340 battery into a device designed for the CR123A, check to see if the manufacturer permits it.

Does this battery have built-in protection?

The Vapcell 16340 T8 850mAh is a battery without a built-in protection circuit. This makes it more compact and suitable for devices designed for a standard cell size. Flashlights such as Zebralight and Dulotec, for example, require batteries without protection. If your flashlight requires a protected battery, consult the seller before purchasing.

What is the charging speed of the Vapcell 16340 T8?

The battery supports normal charging at 500 mA in CCCV mode and cuts off at 100 mA. During fast charging, the current is 1000mA. It is recommended that you use a high-quality charger compatible with 16340 lithium-ion cells to extend the battery’s life.

For which flashlights is the Vapcell 16340 T8 battery suitable?

It is suitable for flashlights and devices that use the 16340 format without protection. It is suitable for Zebralight and Dulotec flashlights, which are specifically designed for unprotected cells. Flashlights from brands such as Acebeam, Olight, Fenix, Nitecore, and Armytec typically require batteries with a protruding positive terminal and a protection circuit—check the specifications of the specific model before purchasing.

How can I tell if I need a protected or unprotected battery?

The easiest way is to measure the original battery in millimeters and compare it to the new battery’s technical specifications. Protected batteries are slightly longer and wider due to the added components. You can also contact the Dulotec.COM team—they’ll help you choose the right battery for your device.

What are the rules for the safe storage of lithium-ion batteries?

Batteries should be stored in a protective case, away from water, fire, and high temperatures. Do not carry them loose in a pocket or bag, as accidental contact with metal objects may cause a short circuit. Do not use a battery with damaged foil. If you suspect damage, do not charge it or insert it into a device.

What is the internal resistance of the Vapcell 16340 T8, and why is it important?

The internal resistance of this battery is 65 mΩ, measured at 1 kHz AC. Lower internal resistance means less energy is lost as heat during discharge. This is an important metric for high-current applications, such as high-power flashlights. A value of 65 mΩ is typical for high-quality cells in this format.
