The widespread AAA/AA design based on Li-ion is revolutionising the mobile energy 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.

Li-Ion technology in LR3/AAA design and constant voltage of 1.5V

The stable and high output voltage makes the 1.5V lithium-ion batteries compatible with all devices that are optimised for operation with disposable batteries and where the low voltage of the NiMH 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 output voltage of 1.5V over the entire cycle.

In addition to 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, but this does not damage the electronically regulated 1.5V Li-ion battery, 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.

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

Disadvantages: The electronic regulation only allows the discharge current specified in the key figures. The batteries can only be recharged via USB or a 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 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 possible via any USB 5V connection (smartphone, mains adapter, powerbank, laptop, etc.), so you remain flexible and always have a charging option 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 characteristics:

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 storage box are included.

Mode of operation:
When using a high-quality 3.7V Li-ion battery with 270mAh, the energy is up to 1000mWh. After the output voltage has been reduced by the electronics to a constant voltage of 1.5V, this corresponds to a capacity of 667mAh.
