Built-in protection circuit

The battery has a built-in protection circuit that protects it from:

reloading
reallocation
overcurrent
short circuit

When critical levels are reached, the protection system automatically shuts down the battery.

Battery with protection—which flashlights is it suitable for?

Protected batteries are slightly longer and wider than standard ones because they contain an additional circuit board. They are suitable for flashlights with mechanical reverse-insertion protection—such as those from Acebeam, Olight, Fenix, Nitecore, Armytec, and similar brands.

They are not suitable for flashlights designed for a standard size without protection—for example, Zebralight and some Dulotec models. Before purchasing, measure the size of the original battery and compare it with the technical specifications. If necessary, contact us for advice.

Frequently Asked Questions

What is the difference between a 16340 battery and an RCR123A?

The 16340 and RCR123A batteries are one and the same—different names for the same lithium-ion cell format. The number 16340 describes the physical dimensions: 16 mm in diameter and 34 mm in height. The name RCR123A comes from the fact that it is the rechargeable equivalent of the disposable CR123A battery. The Keeppower P1634U2 is precisely such a cell, with a capacity of 1000 mAh and built-in protection.

For which flashlights is the Keeppower 16340 protected battery suitable?

Protected batteries are suitable for flashlights designed to work with them—such as those from Acebeam, Olight, Fenix, Nitecore, and Armytec. These models typically feature mechanical reverse-polarity protection. Protected batteries are slightly longer and wider than standard ones, so they are not compatible with all devices. Flashlights such as Zebralight and certain Dulotec models are designed for unprotected batteries. Before purchasing, measure the size of the original battery pack and check the flashlight’s specifications.

How do you charge the Keeppower P1634U2 battery?

The battery charges directly via a built-in Micro USB port with an input voltage of 5V. The charging current is 330 ± 50 mA. There is an indicator light that signals when the battery is fully charged. No external charger is required, making it convenient for everyday use.

How many charge cycles does this battery last?

The Keeppower P1634U2 supports over 300 full charge-discharge cycles. It is important to note that high charge and discharge currents reduce the number of cycles. For a longer battery life, moderate use and storage at an appropriate temperature—between -5°C and 35°C—are recommended.

What do I get when I buy 2 batteries?

When you order 2 Keeppower RCR123A batteries, you’ll receive a free gift—a charging cable and a storage case. The case is especially useful because the batteries shouldn’t be carried loose in a pocket or bag due to the risk of a short circuit.

How can I tell if the battery fits my flashlight?

The most reliable way is to measure the flashlight’s original battery in millimeters and compare it to the dimensions of the Keeppower P1634U2—16.8 mm in diameter and 34.9 mm in height. If the dimensions match and the flashlight supports protected batteries, it is a good fit. If you have any doubts, contact the Dulotec.COM team—we’ll help you choose the right battery pack for your device.

What are the rules for safely storing this battery?

The battery should be stored in a protective case at a temperature between -5°C and 35°C. Do not carry it loose in a pocket or bag. Avoid exposure to water, fire, and extreme temperatures. If the battery has not been used for more than 3 months, charge it before use. Do not use the battery if the foil is damaged or torn.
