Rechargeable lithium battery that is safe to use

The battery has built-in electronic protections against overcharging, overload, short-circuiting, and over-discharge, ensuring a long service life.

Designed for direct replacement of conventional batteries

The high quality Li-ion rechargeable battery from ANSMANN is the perfect replacement for conventional disposable alkaline batteries as it has a higher discharge voltage than conventional rechargeable Ni-Mh batteries (1.2V). Thanks to the built-in voltage converter, the voltage of these Ansmann Li-Ion batteries remains stable at ~1.5V, even when discharged and with a smaller charging capacity. These batteries can be discharged at a wide range of ambient temperatures from -20°C to +60°C.

Due to these features - rechargeable Li-Ion ANSMANN batteries can be widely used where conventional disposable PVZ batteries are commonly used:

• Remote controls
• Digital cameras
• Flashlights
• Razors
• Clocks and other

Easy charging via USB

No need for a special charger thanks to the integrated USB-C connector! The included USB cable makes it easy to charge these batteries (charger not included) - using USB chargers (phone charger, computer USB port, external battery (PwerBank), car USB socket. The battery is equipped with an LED indicator - which flashes red during charging, when the battery is charged - the indicator is steady.

Important: Li-Ion rechargeable batteries can only be charged with the supplied cable!

Lightweight, low self-discharge and many discharge cycles

ANSMANN AA Li-Ion rechargeable batteries are long-lasting and can be recharged more than 1200 times. Thanks to their low self-discharge, they are also ideal for low-energy devices and remain charged for a long time without being used. Li-Ion batteries are much more widely used than other rechargeable battery technologies (PVZ NiCD/NiMH/PB)
