XTAR 18650 2600mAh 5A Battery - Protected Button Top
Key Features
- High-capacity 3500mAh cell for extended runtime
- 5A maximum continuous discharge for steady output
- Protected button top design with built-in PCB safety
- Protection against overcharge, over-discharge, over-current, and short circuit
- Slightly longer than standard flat top 18650 cells due to the protection circuit
Note: This is a button top protected 18650 battery which is longer than a standard flat top unprotected 18650 battery.
Overview
Power compatible electronics with the XTAR 18650 3500mAh 5A battery, a premium protected lithium-ion cell designed for dependable performance and added safety. This button top battery includes an integrated protection circuit board (PCB) that helps guard against common electrical faults during charging and discharging. Because it is protected, it is longer than a standard unprotected flat top 18650—please confirm fitment before use. The outer wrapper and insulator are part of the safety system and must not be removed.
Note: This is a button top protected 18650 and is longer than a standard flat top unprotected 18650 due to the PCB.
Applications/Uses
- High-performance flashlights requiring button top 18650 batteries
- Portable electronics that specify protected 18650 cells
- Emergency preparedness and backup power setups
- Battery-powered devices used for outdoor and travel
- Compatible equipment where built-in battery protection is preferred
