The set of 4 GMCELL AA 1.5V rechargeable batteries is the right choice for users who need a larger energy reserve for multiple devices or for devices that drain batteries quickly. The batteries are built on A-grade 14500 lithium-ion cells, with a constant 1.5V output throughout use, directly replacing any classic AA alkaline battery without any modification to the device.
They are compatible with remote controls, wireless mice, keyboards, gamepads, flashlights, electric toys, smoke alarms, electronic locks, and many other AA-powered devices.
The nominal capacity of 3300mWh per battery provides significantly longer runtime compared to alkaline or NiMH batteries of the same size.
The low internal resistance (22mΩ-45mΩ) ensures a stable and strong discharge current, suitable for high-consumption devices.
Each battery supports up to 1000 charge-discharge cycles, with retention of at least 80% capacity after 3 years. Self-discharge does not exceed 5% per year, allowing long-term storage without significant energy loss.
Charging is done through the integrated USB-C port on each battery. The included cable has a USB-A connector and 4 USB-C branches, allowing all 4 batteries to be charged simultaneously from a single source. Supported charging current is between 1A and 3A, with a full charge in approximately 2 hours at 3A.
The battery integrates a green LED that blinks during charging and stays steadily lit when charging is complete.
The integrated PCB provides full protection: over-discharge, overload, short circuit, overcurrent, and temperature. The batteries are CE, CB, KC, MSDS, and RoHS certified.
