Stop wasting money on standard alkaline AA batteries! Switch to our rechargeable lithium batteries and enjoy the same great performance. Reuse the batteries repeatedly and be more eco-friendly and cost-effective.

The lithium AA battery voltage is 1.5 volts, higher than the NiMH battery voltage. This means you have more options for providing sufficient power for a wide range of products, making them perfect for controllers, keyboards, mice, toys, calculators, wireless devices like toothbrushes, and game controllers, among various other electronic devices.

The batteries come with low power due to transport security measures, but they may reach top performance after 3 cycles of full charge and discharge. We recommend charging the batteries regularly, as long-term idleness may shorten their lifespan. Store them in a clean, dry, and cool place, away from heat and metal objects, to extend their usable life.

The rechargeable AA batteries have a capacity of 3.7V 450mAh and can be fully charged within 1-2 hours. They are rechargeable up to 1200 times and have a standard charging voltage of DC 5V±0.2 and a charging current of DC 5V >0.5A. The standard charging time is 120 minutes, as per the IEC standard.

The batteries feature LED indicators that provide visual feedback on their charging status. The green LED flashes at 1Hz while charging, remains steadily lit when fully charged, turns off during discharge, and flashes at 10Hz when discharging is short-circuited.

If charging with a mobile phone charger, please use a charger rated below 5V2A. These rechargeable AA batteries are compliant with North American safety standards, as well as CE, FCC, and RoHS recognized safety certifications, ensuring user and device safety.

A 12-month warranty is provided for these rechargeable AA batteries, giving you peace of mind and confidence in their quality and performance.
