The UH2670 from Keeppower is a powerful 26650 rechargeable battery with a very high capacity of *7000 mAh and up to 15 A constant discharge current. Ideal for devices with high energy requirements and long runtimes – e.g. powerful LED torches, measuring devices, e-cigarettes (up to max. 80 watts) or DIY applications.
The cell comes unprotected (without PCB) and is therefore intended for users who know how to handle high-performance cells safely.
Unprotected Li-ion cell – only use with external protective circuit or in devices with integrated protection.
Do not deep discharge (below 2.5 V) or overcharge (above 4.2 V).
Only charge with a suitable Li-ion charger (CCCV).
Protect from short circuits, heat and mechanical damage.
Do not throw into fire or open on your own.
Only suitable for experienced users – not a toy!
Store out of reach of children.
Lithium cells may only be operated with protective electronics!
Please note that lithium cells may 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.
* The nominal capacity of a rechargeable 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. Measurements with standard household devices (e.g. USB measuring devices, chargers with an analyser function) often show lower values, as these work under different conditions and cannot achieve the manufacturer’s laboratory conditions.
** The minimum capacity is the minimum value that a battery must reliably deliver. It is guaranteed by the manufacturer, even if there are small deviations during production.

Notes:
Charging lithium-ion batteries requires a special charger that charges the batteries using a special charging process. (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 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 in the municipal collection centres or in the [usually green] containers provided for this purpose by retailers.
