Samsung 18650 29E Rechargeable Battery

The Samsung 18650 29E is a lithium-ion rechargeable battery with a capacity of 2900 mAh and a maximum current of 8A. It features a flat-top design—without a protruding positive terminal.

A battery with or without protection?

Protected batteries have a small circuit board in the anode or cathode that protects the cell from overcharging, over-discharging, and excessive current. When critical thresholds are reached, the protection circuit cuts off the power. These batteries have a raised positive terminal and are suitable for flashlights with mechanical reverse-insertion protection.

Brands such as Acebeam, Olight, Fenix, Nitecore, and Armytec generally work well with protected batteries. Zebralight and Dulotec flashlights, however, are designed for unprotected batteries—protected cells are not suitable for them.

Protected batteries are slightly longer and wider than standard ones. They are not compatible with all devices—some flashlights require a standard size or a higher current, which protected cells cannot provide.

To choose the right battery, measure the dimensions of the original battery in millimeters and compare them with the technical specifications of the new one. If you need help, please contact us—we’ll help you find the right battery for your device.

Safety Rules

Lithium-ion batteries can catch fire or explode if used improperly. Follow these guidelines:

Do not modify, disassemble, puncture, cut, or crush the battery, and do not short-circuit it.
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.

Frequently Asked Questions

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

A flat-top battery has a flat positive terminal, while a button-top battery has a slight protrusion. Some flashlights and devices require a specific type to ensure proper electrical contact. Before purchasing, check which type your device supports. The Samsung 18650 29E has a flat-top design.

Is the Samsung 18650 29E suitable for a Dulotec flashlight?

Dulotec flashlights are designed for unprotected, flat-top batteries. The Samsung 18650 29E meets these requirements. If in doubt, contact the Dulotec.COM team—they will confirm compatibility with your specific flashlight model.

Can I use this battery in an Olight, Fenix, or Nitecore flashlight?

The Olight, Fenix, and Nitecore brands often require batteries with a raised positive terminal or protected cells. The Samsung 18650 29E has a flat top and is unprotected. Check your flashlight’s manual or measure the battery compartment before ordering.

How can I tell which replacement battery is right for my flashlight?

Measure the diameter and length of the original battery in millimeters. Compare these measurements with the technical specifications of the new cell. Check whether the flashlight requires a protected or unprotected battery and whether it needs a flat top or a protruding positive terminal. If necessary, contact us for assistance.

How do I properly store an 18650 lithium-ion battery?

Store the battery in a protective plastic case in a dry, cool place. Never leave it unprotected in a pocket or bag—contact with coins or keys can cause a short circuit. Avoid exposure to direct sunlight and extreme temperatures.

Is it safe to charge the battery in sub-zero temperatures?

Charging lithium-ion batteries at sub-zero temperatures is dangerous and can cause irreversible damage to the cell. Wait until the battery reaches room temperature before placing it in the charger. Discharging at low temperatures is acceptable, but charging is not.

What does a maximum current of 8A mean for this battery?

The maximum discharge current of 8A indicates how many amperes the battery can safely deliver. At higher currents, the battery may overheat or become damaged. The Samsung 18650 29E is optimized for capacity rather than high current—it is suitable for devices with moderate current consumption.
