Battery of the LR6 / AA design with a regulated output voltage of 1.5 volts and an internal lithium-ion battery. Electronically regulated output voltage of 1.5V revolutionise mobile power supply for many standard applications. A built-in Li-ion battery with a nominal voltage of 3.6V to 3.7V is regulated down to 1.5V with the help of electronics in the form of a PCB. The widely used type AAA/AA based on Li-Ion. revolutionise the mobile energy supply for many standard applications.

1.5 Volt AA Mignon LR6 rechargeable batteries based on lithium-ion technology with 3390mWh.

The stable and high output voltage makes the 1.5 volt lithium-ion rechargeable batteries compatible with all devices that are optimised for operation with disposable batteries and where the low voltage of the NiMH rechargeable battery causes problems. The high voltage results in high performance in many devices, e.g. many torches or fairy lights are brighter or motors (toys, kitchen appliances) run faster than with NiMH batteries.

Stable and high output voltage of 1.5V over the entire cycle.

Besides the constant voltage of 1.5V, the battery offers great advantages due to the low-voltage cut-off. Most applications do not have their own low-voltage cut-off, however, do not damage the electronically regulated 1.5V Li-Ion as is the case with NiMH/NiCD batteries. 1000 charging cycles are therefore quite possible with the 1.5V Li-ion battery under real conditions.

Best suited for: game cameras, fairy lights, model making, radios, photo equipment, flash units and many more.

Disadvantages: The electronic regulation only allows the discharge current specified in the key figures. Charging the batteries can only be done via USB or suitable charger.
Please note: Electric motors, e.g. in toy cars, require several times the current than the specified continuous load when starting up;

Important: Charging of the Keeppower 1.5V Li-Ion. Batteries is only possible via the integrated micro USB socket. Charging with a conventional charger for NiMH/NiCD or Li-Ion batteries is not permitted.
Chargers for Li-Ion 1.5V batteries from other manufacturers are not compatible.
Charging is done via the integrated USB socket on any 5V USB connection. Coloured LED on the front of the batteries informs the user about the charging status. Charge your batteries on the go at any USB-5V port, (smartphone power supply, powerbank, laptop etc.), thus you stay flexible and always have a charging possibility at hand.

Safety instructions:

Please note that lithium cells should only be used by competent persons.
Incorrect handling or short-circuiting may result in fire or explosion.

Further properties:

Lithium-ion batteries are thermally stable and are not subject to memory effect.
They work on the basis of lithium and are characterised by a high energy density.

Scope of delivery:

1x 1.5V Li-ion rechargeable batteries 
When ordered in pairs (2 pieces), a USB cable with two micro USB plugs and a battery box are included.

Mode of operation:
Using a high quality 3.7V Li-ion 900mAh battery, the energy is up to 3390 mWh. After the output voltage has been reduced by the electronics to a constant voltage of 1.5 V, this corresponds to a capacity of 2260mAh.
