Ansmann AAA battery (rechargeable) Li-ion 400 mAh 1.5 V 4 pc(s)

The safe rechargeable battery
Integrated electronics protects the cell against overloading, overload, short-circuit and deep discharge. As such, the battery is perfectly protected against wrong handling, WAS guarantees a long life.

The perfect replacement for batteries
The high-quality lithium-ion (Li-ion) battery by Ansmann is the ideal replacement for 1,5V alkaline single-use 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. Along with being rechargeable, it also scores high, thanks to integrated electronics, with a constant output voltage of 1,5V over 95% of the operating time. If the battery still has a remaining capacity of approx. 5%, the output voltage is reduced to 1.1V to signal to the user that the battery should be changed. For example, the constant output voltage of the Ansmann 1.5V Li-Ion rechargeable batteries means that a torch always lights up uniformly, or that a milk frother, electric toy or a shaver always runs with even, full Power.
In contrast, with alkaline batteries, the voltage varies between 1,6V in their new state and 0.9V when the battery is almost exhausted. For this reason, the Power continues to fade when alkaline batteries are used in many devices.
In comparison 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 are particularly weak at low temperatures in comparison to Ansmann Li-Ion rechargeable batteries. Application examples for these are e.g. electronics. Toys, torches, radios, measuring devices, security cameras, Soap dispenser, electronic. Door locks etc.

Simple charging via USB
Due to the integrated USB-C charging port, no additional chargers are necessary! For each size a suitable USB-C cable is included in the delivery. With this, 4 AAA batteries can be charged simultaneously with just one cable. This guarantees safe and simple charging via all available USB charging options such as laptop, power bank, USB charger for the mains socket or car or built-in USB chargers in the wall or in the car. The display at the plus pole of the rechargeable battery blinks during the charging process. Once the charging is complete, it stays lit.

Low weight, low self-discharge and high cycle strength
The Ansmann micro AAA Li-ion battery has an extremely long life and can be charged up to 1500 times even under harsh operating conditions. Due to the very low self discharge, the battery retains its energy over a long period of time even when it is not in use. In addition, the weight of the Li-ion cell is much lower than with conventional battery technologies (e.g. NiMH/PB) at the same power.
