New chemical and technical possibilities have led to a significant increase in the performance of Li-ion batteries, largely optimising their capacity and efficiency. Two charging options, via a USB-C or as usual in a charger, open up new possibilities through high flexibility.

USB-C charging port, for more flexibility and robustness.

With IC protection/PCB with short-circuit, overcharge and deep discharge protection, the battery is suitable for all devices that do not have their own protection electronics and are perfectly protected against incorrect handling, guaranteeing a long service life.

Keeppower P1840TC, powerful and reliable

Charge your batteries in the charger or on the go with any USB 5V connection (smartphone power supply, power bank, laptop, etc.), so you remain flexible and always have a charging option to hand.

Please note the dimensions of the cell before purchasing! Due to the built-in electronics, the cell is not suitable for every application!
Height and diameter are larger than a standard 18650 cell without **PCB.

Safety instructions:

Please note that lithium cells may only be used by qualified persons.
Incorrect handling or short circuits can lead to fire or explosion.

Further properties:

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.

Scope of delivery:

1 x 18650 Keeppower rechargeable battery with USB charging option.
When ordered in pairs (two units), the batteries are supplied with a battery storage box and Y USB-C cable.

* The nominal capacity of a battery indicates the amount of energy it can store under ideal laboratory conditions. This value is measured at a constant temperature and under defined conditions in order to create a reliable reference for the performance of the battery.

**A PCB (Printed Circuit Board) is the printed circuit board on which the circuit is located.
**A battery management system(BMS) or simply battery management is a measure, but usually an electronic circuit, which is used to monitor, control and protect batteries.

Notes:

Charging lithium-ion batteries requires a special charger that 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 number of charging cycles (possibly up to double). Only lithium-ion chargers may be used for charging. However, 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 low 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 in the municipal collection centres or in the [usually green] containers provided for this purpose by retailers.
