Rechargeable 18650 Lithium-Ion Battery No name ARB-L18 3400 mAh 3.6 V

Rechargeable 18650 Lithium-Ion Battery No name ARB-L18 3400 mAh 3.6 V is a single cylindrical cell designed to provide a compact, replaceable power source for devices that accept 18650-format batteries. The cell offers a nominal capacity of 3400 mAh and a nominal voltage of 3.6 V, making it suitable for flashlights, power banks, portable electronics and other consumer devices that rely on 18650 batteries. The battery is intended to deliver stable voltage output and extended runtime compared with lower-capacity cells.

Advantages

The battery combines a relatively high nominal capacity with the standard 18650 form factor, allowing straightforward replacement in compatible devices. Built-in protection against deep discharge supports longer usable life by preventing cell damage from over-discharge. Stable voltage output under typical loads helps maintain device performance and predictable runtime. Its rechargeable lithium-ion chemistry enables repeated charge cycles and reduces the need for disposable cells.

Suitable for

• Handheld flashlights and torches that accept 18650 cells
• Portable power banks and DIY battery packs
• Vaporizers and personal electronics compatible with 18650 batteries
• LED work lights, bike lights and other portable lighting devices
• Rechargeable electronic projects and hobbyist applications

Key specifications

• Cell format: 18650 cylindrical cell
• Nominal capacity: 3400 mAh
• Nominal voltage: 3.6 V
• Chemistry: lithium-ion
• Rechargeable: yes
• Protection: over-discharge protection (typical for designated protected cells)

How to use

Insert the battery into the device following the correct polarity indicated by the device manufacturer. Use a compatible charger designed for 18650 lithium-ion cells and observe the charger's instructions. Do not attempt to charge the cell in chargers not intended for lithium-ion chemistry. Replace single cells only with the same format and similar capacity when used in multi-cell assemblies, and ensure proper matching of voltage and state of charge when assembling packs.

Usage recommendations

Store and charge the battery at moderate temperatures, avoid exposure to extreme heat or moisture, and do not subject cells to mechanical shock or short circuits. For safe long-term use, follow device manufacturer guidelines regarding cell orientation, battery holders and protective circuitry. Recycle used cells responsibly at designated collection points.
