Ansmann 1311-0028 household battery Rechargeable battery AAA Lithium-Ion (Li-Ion)

The safe battery
The integrated electronics protect the cell from overcharging, overloading, short circuits and deep discharging. As a result, the battery is perfectly protected against incorrect handling, which guarantees a long service life.

The perfect replacement for regular batteries
The high-quality lithium-ion (Li-Ion) rechargeable battery from ANSMANN is the ideal replacement for 1.5V disposable alkaline batteries or rechargeable 1,2 V NiMH batteries. While some battery-operated devices have problems with the lower output voltage of NiMH batteries, the ANSMANN 1,5 V Li-Ion battery is fully compatible with alkaline batteries. In addition to its rechargeability, it also scores with a constant output voltage of 1.5V over 95% of the operating time thanks to its built-in electronics. If the battery still has a residual capacity of approx. 5%, the output voltage is reduced to 1.1V to signal to the user that the battery should be replaced. The constant output voltage of the ANSMANN 1.5V Li-Ion rechargeable battery ensures, for example, that a torch always shines brightly and evenly, or that a milk frother, electric toy or shaver always runs at full power.
In contrast, the voltage of alkaline batteries fluctuates between 1.6V when new and 0.9V when the battery is almost exhausted. Therefore, when using alkaline batteries, the power of many devices continues to decrease.
Compared to alkaline batteries, the ANSMANN 1.5V Li-Ion has another major advantage: It can be used over a wide temperature range from -20°C to +60°C. Alkaline batteries weaken much earlier than the ANSMANN Li-Ion battery, especially at low temperatures. Typical application examples for these are, for example Electric toys, torches, radios, measuring devices, security cameras, soap dispensers, electric door locks, etc.
Note: Li-Ion rechargeable battery can only be charged via the USB to USB-C cable supplied!

Low weight, low self-discharge and high cycle stability
The ANSMANN AAA Li-Ion rechargeable battery is extremely durable and can be recharged up to 1200 times, even under tough conditions. Thanks to the very low self-discharge rate, the battery retains its energy over a long period of time even when not in use. In addition, the weight of the Li-ion cell is much lower compared to conventional battery technologies (e.g. NiMH/PB) with the same performance.
