BAK N21700CD-53E with 5300mAh 10A 3.6V – 3.7V Li-ion battery

The N21700CD-53E from BAK is a perfect replacement for Samsung, Murata (Sony), LG or Panasonic cells. High quality standards, years of experience and advanced technology make BAK cells a serious competitor to the well-known brands.

Due to the shortage of rechargeable batteries on the international market, cells such as the N21700CD-53E will play a major role. For many battery pack manufacturers, the batteries from BAK, Lishen or DLG will make a decisive contribution and provide an equivalent replacement.

Innovative manufacturing processes in the BAK factories enable competitive products at the best price-performance ratio. BAK is an internationally operating company and the European branch has been located in Germany for several years. Thanks to the innovation of its own factories, BAK is able to keep up with the high-calibre competition and in some cases even surpass it.

Lithium cells may only be operated with protective electronics!
Please note that lithium cells may only be used by authorised specialist personnel.
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.

*Further options:

No selection: Battery cell without options as in the main picture.
– Raised positive terminal: A button (nipple) welded to the positive terminal using a special welding process raises the flat positive terminal by approx. 2 mm, similar to a normal battery, for example (for an additional charge).
– Solder lug: A metal tongue that is firmly connected to the positive and negative terminals of the battery and is used to solder a connecting wire or additional batteries to the component (at an extra charge).
U – Both solder tags point in one direction (e.g. for parallel connection or soldering to electronic components)
Z – Solder tags point in opposite directions. (e.g. series connection or construction-related soldering)

Technical Data

Notes:

Charging lithium-ion batteries requires a special charger that charges the batteries according to a special charging procedure (CCCV = constant current, constant voltage). (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.
