XTAR Rechargeable Raw Li-ion 18650 Battery, 3500 mAh, 3.6V

XTAR Rechargeable Raw Li-ion 18650 Battery, 3500 mAh, 3.6V

The rechargeable XTAR 18650 RAW Li-ion cell offers a capacity of 3500 mAh, a nominal voltage of 3.6 V, and a maximum discharge current of 10 A. It provides stable performance and long-lasting power for devices with higher energy demands. A lifespan exceeding 500 charge cycles allows for long-term and repeated use, while the operating range from –20 to +60 °C ensures reliability in various conditions.

This is a unprotected cell without its own protection electronics. It is therefore intended for compatible devices or battery systems with external BMS protection, which ensures safe charging and discharging. Before use, it is necessary to verify support for the 18650 format, the Flat Top design, and the corresponding device protection.

High capacity of 3500 mAh

The 3,500 mAh capacity provides enough power for long-term operation of compatible devices. The high-quality Li-ion cell offers stable performance and helps reduce the need for frequent charging or battery replacement.

Unprotected RAW design

The battery is supplied as a unprotected RAW cell without its own protection electronics. It is primarily intended for compatible devices and battery packs equipped with an external BMS system, which provides protection against overcharging, over-discharging, short circuits, and overloading. When properly connected, the cell delivers high performance, a stable power supply, and allows you to build a battery system tailored to your specific requirements. Before use, verify device compatibility and use an appropriate charger for Li-ion cells.

Discharge current up to 10 A

The maximum discharge current 10 A allows the cell to be used even in devices with higher power demands. The battery provides a stable power supply even under heavy loads and maintains consistent performance during operation.

More than 500 charge cycles

A service life exceeding 500 charge cycles allows the cell to be used repeatedly over a long period of time. When properly charged, stored, and used, it provides a reliable source of energy without the need for frequent replacement.

Reliable performance in various conditions

An operating range from –20 to +60 °C allows the battery to be used in both cold and warm environments. The cell can thus ensure a stable power supply to devices under various operating and climatic conditions.

Mercury-, lead-, and cadmium-free

The battery does not contain hazardous substances such as mercury, lead, and cadmium, and meets the relevant requirements for safe material design. The ability to recharge it also helps reduce the consumption of disposable batteries. At the end of its service life, the battery must be returned for professional recycling.

Compact 18650 format and Flat Top

The cell measures approximately Ø 18.35 × 65 mm and features a flat positive contact Flat Top. Before use, you must verify that your device supports the 18650 format, unprotected cells, and this type of contact.
