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).

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.

*More options:

• No selection: battery cell comes without options as seen in the main picture.
• Raised positive pole: Button (nub) welded to the positive pole using a special welding process increases the flat positive pole by approx. 2 mm, similar to a normal battery, for example. (for a surcharge)
• Soldering lug: A metal tab (W: 7mm x L: 25mm x D: 0.15mm), which is firmly connected to the battery at the plus and minus pole and is used to solder a connecting wire or other batteries to the component. (for a surcharge)
    U - Both soldering lugs point in one direction (e.g. for parallel connection or soldering to electronic components)
    Z - Solder tabs point in opposite direction. (e.g. series connection or design-related soldering)


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.

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.
