KeepPower 18500 P1850J2 2000mAh

Battery for ACUS M1 / ACUS M1Plus
Set of two rechargeable 18500 lithium-ion batteries with protection circuit. These rechargeable batteries are 54mm long, have a capacity of 2000mAh, and comply with the technical standards of the Electrical Appliance and Material Safety Law (PSE). Before purchasing, please make sure that the size is compatible with your equipment.
The highly reliable combination of high performance and high quality Panasonic NCR18500 cell and Seiko Instruments Inc. IC chip is used for the protection circuit. When the voltage exceeds the upper and lower specified values, the protection circuit is activated to cut off the energization. It protects batteries from undercharging, overcharging, overdischarging, overcurrent, overshort-circuiting, ignition and rupture.
Compared to the total capacity of three alkaline batteries, it has 2 to 2.5 times the capacity/voltage and can be used repeatedly by recharging. The performance is not easily degraded and has a cycle life of about 500 cycles.
For long-term storage, please keep the batteries fully charged and store in a cool, dark place with little humidity. Avoid places exposed to direct sunlight or condensation. Ignition of lithium-ion batteries cannot be extinguished with water and requires a special chemical fire extinguisher.
For transportation safety, the product is shipped uncharged and must be charged before use. A KEEPPOWER charger is recommended for recharging.
