【3600mWh LONG LASTING POWER】
imuto 3600mWh rechargeable lithium AA batteries are designed for high-drain devices, providing longer usage time between charges, making it ideal for power-hungry devices that consume more energy over time. (3600mWh ≈ 2400mAh)
【1.5V CONSTANT VOLTAGE OUTPUT】
imuto 1.5V rechargeable AA lithium batteries deliver a consistent and stable 1.5V voltage output throughout the discharge cycle, have a stronger energy output than 1.2V NiMH batteries, and can power a wider variety of devices.
【1600 CYCLE LIFE】
imuto AA rechargeable lithium batteries have an amazing cycle life of up to 1600 charging cycles with no memory effect. It can effectively reduce your battery costs and carbon footprint.
【VERSATILE APPLICATIONS】
imuto 3600mWh rechargeable AA lithium battery is perfect for a variety of continuous high-drain devices, including video doorbell, security camera, trail camera, smoke detector, smart lock, and solar light.
【AA LITHIUM BATTERY FAST CHARGING CASE】
imuto double A rechargeable lithium batteries with charger set includes 8 batteries and a fast charging case. The charging case can fully charge 1-8 batteries with a capacity of 3600 mWh in about 3 hours, which is 40% more efficient than NiMH batteries. (Please use 5V/3A adapter for quick charging)
【CHARGING, STORAGE, PROTECTION IN ONE】
imuto AA lithium battery charging case adopts magnetic closure and an independent battery slot design, which not only allows for fast charging but can also be used as a battery storage box for organized battery storage, and provides protection against moisture, dust, pressure, and splashes to ensure battery safety and is easy to carry on the go.
【OVER-DISCHARGED BATTERY RE-ACTIVATION】
imuto AA lithium-ion batteries charging case has a microcurrent function. The smart chip can identify over-discharged batteries, and then reactivate batteries that have been excessively discharged by applying a gentle microcurrent, restoring them to usable condition.
I ordered a package of 8 AA Imuto batteries as well as the charging case. The device looks really good and of high quality. The mechanical construction is very well executed, and the manufacturing quality also looks good. The idea of the device is excellent: the batteries stay safely stored in their own case, where they are charged centrally through a single connection.
I was very curious to know how well the given capacity values hold up. I fully charged the batteries and built a simple discharge device with which I could measure the battery capacity. I connected 4 batteries in series and discharged them through a 33-ohm resistor, measuring the discharge voltage once per hour. The discharge current changed accordingly as the voltage dropped. After 11.75 hours, the pack voltage had fallen to 3.45 volts, and I stopped the measurement at that point.
The result of the measurement was that the capacity was 2000 mAh and 2850 mWh. This is clearly lower than the promised 2400 mAh and 3600 mWh, but still a reasonably good result. Of course, the accuracy of the measurement is not the same as in a certified laboratory, but it does give a good idea of the capacity.
good
