2)Durable: Batteries rechargeable up to 500 times! 


3)Built-in PTC: Using an innovational positive protection circuit and its positions on the positive of battery which is different from traditional circuit protecting board placement, that acts as a circuit breaker to shut down the battery if it gets too hot


4)Triple Overheat Protection: automatically protects against overcharge, over discharge and short-circuiting. 


5)External safety features: equipped at both ends with a nickle-plated S.S protector ensuring high impact resistance, good electrical conductivity and oxidation resistance; tough plastic circuit board protector; coated with durable metallic film to guard against abrasion. 


Please Notice: Since protected board was compatible with USB-Micro charging, the length (69mm) is longer than conventional 18650 battery. Please take carefully consideration before using on other devices.
