Lithium-ion batteries that revolutionise the mobile power supply for many standard applications with an electronically regulated output voltage of 1.5V.
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 rechargeable batteries.
In addition to the constant voltage of 1.5V, the battery offers major advantages thanks to the undervoltage cut-off. Most applications do not have their own undervoltage cut-off, but this does 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 lithium-ion battery under real conditions.
Disadvantages: The electronic control only allows the discharge current specified in the key figures. The batteries can only be charged with a suitable charger.
Please note: Electric motors, e.g. in toy cars, require several times more current to start up than the specified continuous load.
Important: The Keeppower 1.5V Li-ion batteries can be charged via the integrated micro USB socket or with the XTAR BC4, XTAR L4, XTAR L8, XTAR MX4, XTAR VX4 or Soshine Chocolate 1.5V charger. Charging with a conventional charger for NiMH/NiCD or Li-ion batteries is not permitted.
Chargers for Li-ion 1.5V batteries other than the models listed are not compatible. Charging via USB is possible with any USB 5V connection (smartphone, mains adapter, power bank, laptop, etc.), so you remain flexible and always have a charging option to hand.

Please note that lithium cells should only be used by qualified persons.
Incorrect handling or short-circuiting can lead to fire or explosion.
Lithium-ion batteries are thermally stable and are not subject to a memory effect.
They work on the basis of lithium and are characterised by a high energy density.

Mode of operation:
A built-in Li-ion battery with a nominal voltage of 3.6V to 3.7V is regulated down to 1.5V using electronics in the form of a PCB. The widespread AAA/AA design based on Li-ion is revolutionising the mobile power supply for many standard applications.
When using a high-quality 3.7V Li-ion battery with 800mAh, the energy is up to 2925 mWh. After the output voltage has been reduced to a constant voltage of 1.5 V by the electronics, this corresponds to a capacity of 1950mAh.
