AA lithium battery charger, 1300 mWh triple-A battery with 1.5 V constant voltage, over 1600 charging cycles

【Over 1600 Lifespan Cycles】One AA lithium battery can be recharged up to 1600 times, equivalent to thousands of dry cell batteries. Its 12-year lifespan, low self-discharge, and longer lifespan result in significant savings compared to disposable batteries. (Battery not included)

【1.5V Constant Voltage Design】The built-in intelligent constant voltage charging chip precisely controls the charging process and effectively prevents damage caused by voltage fluctuations during charging and discharging. This extends battery life. After multiple charge and discharge cycles, the battery capacity remains virtually unchanged, prolonging its lifespan.

【Integrated Charging and Storage】The 8-slot charger can charge 1 to 8 AA batteries simultaneously.

【2.2-Hour Fast and Smart Charging】Fast and fully charges 1 to 8 AA lithium batteries in just 2.2 hours, reducing your waiting time. The Type-C charging port is compatible with all kinds of interfaces: laptop, car charger, power bank, and adapter for more flexible charging. The built-in smart chip intelligently recognizes non-rechargeable lithium-ion batteries, protecting both the battery and the charger from damage during charging. Note: The maximum discharge current of a 1.5V AA lithium battery is 0.5A. Due to different circuit designs, some high-power LED flashlights and headlamps may cause the battery to overcharge and overheat. If your device has a high-brightness/intense light mode, be mindful of its high current. Prolonged use of the maximum current and overcurrent can cause the battery to overheat.
