【Flat Top Size】2.56*0.71*0.71 inch(65*18*18 mm). Standard flat top design fits most battery compartments. IMPORTANT: Please double-check your device's battery size and type (flat top vs. button top) before purchase to ensure compatibility.
【Versatile Compatibility】Our 18650 rechargeable battery works seamlessly with a huge range of electronics: headlamps, flashlights, doorbells, security cameras, mini fans, RC toys, power banks, and more. Keep all your essential gear powered up and ready to use anytime, anywhere.
【High Performance】Powered by a 9900mAh high-density cell, this battery delivers exceptional runtime—far longer than standard rechargeable batteries. No memory effect means you can charge it at any time without reducing capacity. With 1000+ charge-discharge cycles, it replaces disposable batteries and saves you money long-term.
【Advanced Safety Features】Built-in 6-in-1 protection system: under-voltage, over-voltage, over-current, over-temperature, short-circuit, and anti-reverse connection protection. These safeguards stabilize voltage/current, prevent overheating, and stop damage from incorrect insertion. Use it safely for home, outdoor, and professional devices.
【Warm Tips for Optimal Use】Fully charge the battery immediately upon receipt. Recharge promptly when the battery is low (avoid deep discharge). Store in a cool, dry place (15-25°C/59-77°F) when not in use. Do not mix with different battery types or brands. Following these steps extends cycle life and ensures consistent performance.
