Rechargeable Li-ion Battery No name ARB-L14 14500 1050 mAh 3.6 V

The Akumulator Fenix ARB-L14 (14500 1050 mAh 3,6 V) is a rechargeable lithium-ion cell designed for compact devices that require a high-energy, small-diameter power source. This 14500-size battery delivers nominal 3.6 V voltage and 1050 mAh capacity, offering a balance between runtime and compact form factor for portable electronics. The cell is suitable for single-cell applications or as part of a multi-cell battery pack where 14500 dimensions and lithium chemistry are required.

Advantages

This rechargeable 14500 cell provides a stable nominal voltage of 3.6 V and a rated capacity of 1050 mAh, enabling longer operation compared with lower-capacity cells of the same size. The lithium-ion chemistry ensures a favorable energy-to-weight ratio and low self-discharge when stored under recommended conditions. The cell’s standard 14500 dimensions make it compatible with devices designed for that format, and the consistent performance characteristics simplify power planning for compatible equipment.

Suitable for

• Portable flashlights and headlamps designed for 14500 cells
• Handheld electronic devices requiring a 3.6 V lithium-ion cell
• Battery holders and DIY electronics projects using 14500-format cells
• Backup power for small sensors, remote controls, and USB adapters compatible with 14500 size

Key specifications

• Cell format: 14500 (standard AA-diameter, shorter length compared to 18650)
• Nominal voltage: 3.6 V
• Rated capacity: 1050 mAh
• Chemistry: lithium-ion
• Typical use: single-cell applications or integration into small multi-cell packs

How to use

Use the battery in devices specified to accept 14500-format lithium-ion cells with a nominal voltage of 3.6 V. Insert the cell observing correct polarity and any device-specific orientation markings. Charge the cell only with a charger intended for lithium-ion batteries and compatible with the 14500 size; follow charger manufacturer instructions for charging current and termination method. Do not attempt to force a mismatched cell into a compartment designed for different sizes.

Usage recommendations

Store the battery in a cool, dry place away from direct heat and sunlight. For long-term storage, keep the cell partially charged (around 30–50% state of charge) and check the voltage periodically. Do not expose the cell to water, mechanical shock, or temperatures outside the recommended range. Dispose of or recycle the battery according to local regulations for lithium-ion cells.
