What's Included 4 Pack: - 4 Pale Blue AA Batteries - 1 Charging Cable 8 Pack: - 8 Pale Blue AA Batteries - 2 Charging Cables 12 Pack: - 12 Pale Blue AA Batteries - 3 Charging Cables Technical Specifications Chemistry: Lithium Ion Power [W-h]: 2.25 Watt hours Voltage: 1.5V Capacity: 1560 mAh Charge Time: Under 2 hours (depending on charger specifications) Cycle Rating: 1000+ Cycles Charging Cable: USB to 4 Micro USB Charge State Indicator: Red Green LED Protection Circuit: Integrated safety circuit protects battery and device Overheat Protection: Operating at max output the battery will not overheat, this is part of the protection circuit. Other Safety Protections: Protects against Overload, Leakage, Short Circuit, Over Voltage, & High Temperature Certifications: IEC 62133, CE, FCC, PSE, UN38.3, RoHS, REACH Operating Temperature Rage: -20c -> 60c, (-4F-> 140F) Self-Discharge: The dormant / self discharge characteristics of Pale Blue batteries are very low. This is one of the advantages of a lithium ion battery with a control circuit, vs an alkaline or NiMh battery, where the cell discharges directly into the circuit (no control circuit). The battery life in dormant mode depends partly on the environment. High ambient temperatures, and higher humidity, increases the internal drain. But in normal circumstances a battery installed in a device, like a door lock, will last ~12 months. Cells Per Battery: 1 Lithium Content: 0.165g Individual Battery Weight: 17.5g
