Rechargeable Li-ion Battery Nitecore NL1836 3.6V 3600mAh cylindrical cell

Nitecore NL1836 is a rechargeable Li‑ion cylindrical cell with a nominal voltage of 3.6 V and a rated capacity of 3600 mAh. The cell is intended to deliver a stable single‑cell output for devices that require a high‑capacity Li‑ion battery. Its form factor suits flashlights, portable electronics and various battery‑powered tools where a single replaceable rechargeable cell is used. The cell should be charged with compatible chargers and handled according to standard Li‑ion safety guidelines for charging, storage and disposal.

Advantages

The NL1836 offers a high energy capacity in a cylindrical format, providing extended runtime compared with lower‑capacity single cells. As a rechargeable Li‑ion cell it supports multiple charge cycles while maintaining a relatively stable voltage under load. Its standardized shape and nominal voltage simplify replacement and integration into devices designed for a single 3.6 V cell. The battery’s construction provides reliable output suitable for both constant and variable loads typical of flashlights and portable electronics.

Suitable for

• High‑capacity LED flashlights and torches
• Portable audio players and handheld electronics
• Battery‑powered tools and measurement instruments that accept a single cylindrical Li‑ion cell
• Replacement in devices originally specified for a 3.6 V cylindrical Li‑ion cell

Key specifications

• Chemistry: Lithium‑ion (Li‑ion)
• Nominal voltage: 3.6 V
• Rated capacity: 3600 mAh
• Cell type: Cylindrical rechargeable cell
• Intended use: Single‑cell applications requiring high capacity

How to use

Insert the NL1836 cell into devices following the polarity markings and device manufacturer instructions. Charge the cell with a charger designed for Li‑ion chemistry and compatible with single cylindrical cells, observing the charger’s voltage and current limits. Avoid short circuits, mechanical damage and exposure to extreme temperatures. Do not mix cells of different types, capacities or states of charge in multi‑cell devices.

Usage recommendations

Store the cell in a cool, dry place at partial charge for extended storage. Use a dedicated Li‑ion charger and stop charging if the cell or charger becomes unusually hot. Follow local regulations for disposal or recycling of lithium‑ion batteries.
