Due to the shortage of battery cells, Efest decided to develop its own. Efest kept the focus on the very popular range in the vapor scene from 20Watt to 50Watt. The cell is also ideally suited for use in smaller battery packs or torches.
The INR18650-30EF from Efest is a perfect replacement for the INR18650-30Q from Samsung. With the shortage of batteries in the international market, cells like the INR18650-30EF will play a big role.

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 may result in fire or explosion.
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.
1x Efest INR18650-30EF – 3000mAh, lithium-ion rechargeable battery.
*Other options:
No selection: battery cell without options as in the main picture.
– Raised positive terminal: A button (nipple) welded to the positive terminal by means of a special welding process raises the flat positive terminal by approx. 2 mm, similar to a normal battery (for an additional charge).
– Solder tag: A metal tongue (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 further 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 direction (e.g. for series connection or soldering to electronic components).

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.
