Stay flexible on the road or at home. Charge your batteries on any 5V USB power supply or as usual in the application or charger. Using the latest industrial cells of size 14430, the battery is no longer than standard AA (Mignon) battery.

Li-Ion Battery 14500 3.6V - 3.7V 1100mAh in size AA (Mignon)

Thanks to further development with the most modern chemical components the P1411U realises the length of a AA battery<50.5 despite BMS/PCB electronics and USB charging socket, this battery reaches a capacity of over 1000mAh. Ideally suited for applications such as torches, camping lamps, searchlights and other electronically powered devices where usability of several hours is a criterion.

Integrated Micro-USB charging socket and charging electronics.

With charging indicator. Built-in PTC to prevent high current surges. Innovative anode design with high temperature resistance. Pressure relief valve activates on rapid temperature rise. IC protection/PCB with short circuit, overcharge and deep discharge protection. 
 

Safety instructions:

Please note that lithium cells may 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.
No charger is required to charge this battery. The P1411U has an integrated micro USB port that allows users to charge the battery directly from a compatible USB power source.

Supplied with:

1 x 14500 Keeppower battery with USB charging capability.
When ordered in pairs (two pieces), the batteries come with a battery storage box and USB cable for two batteries.

Notes:

A special charger is required for charging lithium-ion batteries, which charges the batteries according to a special charging procedure. (CCCV = constant current, constant voltage.) The batteries must not be charged above a voltage of 4.2 volts, otherwise there is a risk of fire and explosion. It is advantageous to charge the batteries only up to approx. 4.1 volts, as this significantly increases the service life or the number of charging cycles (possibly up to double). Only lithium ion chargers may be used for charging. However, the cheap chargers sometimes have the disadvantage that they do not switch off safely at the end of the charging process, but continue to charge the batteries with a small charging current, which can be dangerous.

Furthermore, rechargeable batteries and batteries do not belong in household waste! Please dispose of them as prescribed by law at the municipal collection points or in the [usually green] containers provided by retailers.
