If you are looking for an inexpensive cell for storage systems or as a power supply for numerous mobile applications such as e-bikes, power banks, torches and much more, the H18650CQ is the perfect choice.

Standard cell with 2550mAh and max. 10.2A discharge current, BAK H18650CQ.

Due to the shortage of batteries on the international market, cells like the H18650CQ will play a major role. For many battery pack assemblers, the batteries from BAK, Lishen or DLG will make a decisive contribution. As a replacement for the ICR18650-26F or ICR18650J from Samsung.

The cells are not suitable for applications with high current output (e-cigarettes or power tools).
Suitable for: storage systems, e-bikes, laptop, LED applications, model making and anywhere constant discharge current does not exceed 3C (7.655A).

Short info to manufacturer:

Innovative manufacturing processes in the BAK factories enable competitive products at the best price/performance ratio. BAK is an internationally operating company. The branch office responsible for Europe has been located in Germany for several years. Due to the innovation of its own factories, BAK is able to keep up with and partly surpass the top-class competition.

Safety instructions:

Lithium cells may only be operated with protective electronics!
Please note that lithium cells may only be used by authorised qualified personnel.
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 BAK H18650CQ Lithium-ion battery

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 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.
