XTAR 18650 3600mAh 10A Battery - Protected Button Top

Key Features 3600mAh High Capacity: Delivers 3600mAh nominal capacity at 3.6V for extended runtime in flashlights and compatible button top 18650 devices — ideal for high-output lighting applications demanding long per-charge endurance. 10A Maximum Continuous Discharge: Supports up to 10A maximum continuous discharge current for reliable, stable power delivery in compatible single-cell and multi-cell applications. PCB Multi-Protection Circuit: Integrated protection board guards against overcharge, over-discharge, and short circuit conditions for safe, reliable operation in compatible devices without the need for an external BMS. 500+ Cycle Life with Low Self-Discharge: Rated for over 500 charge/discharge cycles with a low self-discharge rate, ensuring long-term cost efficiency and reliable charge retention between uses. Button Top Terminal: Positive button top configuration ensures broad compatibility with devices designed for button top 18650 cells — note that this cell is physically longer than a standard flat top unprotected 18650 battery due to the added PCB and button top terminal. Note: This is a button top protected 18650 battery which is longer than a standard flat top unprotected 18650 battery. Overview The XTAR 18650 3600mAh Protected Button Top battery is a high-capacity, PCB-protected lithium-ion cell engineered for flashlights and other compatible button top 18650 devices requiring both extended runtime and built-in cell-level safety protection. Delivering 3600mAh at 3.6V nominal voltage with a 10A maximum continuous discharge rating, it provides the capacity and current output needed for demanding lighting and portable electronic applications. The integrated multi-protection circuit board safeguards against overcharge, over-discharge, and short circuit conditions, enabling safe operation in compatible devices without an external BMS. A rated cycle life of over 500 charges and a low self-discharge rate make this cell a reliable and economical long-term power solution. This protected button top cell is physically longer than a standard flat top unprotected 18650 battery — always verify dimensional compatibility with your device before purchase. Do not remove the protective wrap, as doing so may compromise the protection circuit.
