Samsung INR18650-25R 2500 mAh 3.6V – 3.7V Li-ion industrial cell.

Although the cell was already a perennial favourite in the first stage of development, it has undergone several stages of development up to the present day and has reached a state where one has to pronounce it more than mature.

Thanks to its outstanding performance, stable properties and high demand, the already very mature SDI industrial cell is manufactured and continuously developed further.

Please note: The industrial cell has no integrated PCB/BMS electronic protection circuit and insufficient insulation for normal household use (e-cigarette, torch, etc.) as well as a lack of labelling. The industrial cells are designed for further processing into battery packs or integrated use.
For use in e-cigarettes or e-shisha, Keeppower offers theINR18650-25Rcells, which aresufficiently insulated and labelled with important key figures and are suitable for use in devices equipped exclusively with protective electronics.

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.

*Further options:

Without extras: 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 (at extra cost).
– Solder lug: A metal tongue (W: 7mm x L: 25mm x D: 0.15mm), which is firmly connected to the positive and negative terminals of the battery and is used to solder a connecting wire or other batteries to the component. (for 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)

The industrial cells are intended for further processing (labelling of the cells is not sufficient for B2C)
The batteries are not suitable and intended for normal household use.

Technical Data

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 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.
