An 18350 Li-ion cell is a rechargeable battery with a diameter of approx. 18 mm and a length of approx. 35 mm. This compact design makes it ideal for applications where space is limited but high power output is required, such as in torches or other portable devices.
It is important to note that the actual capacity and maximum discharge currents may vary depending on the manufacturer and specific model. When selecting a battery, always consider the requirements of the specific device and the specifications provided by the manufacturer.
Please note that lithium cells should 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.
1x 18350 Li-ion rechargeable battery
If ordered in pairs (two batteries), a battery box for 2 batteries is supplied.
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 an extra charge).
– 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 soldering due to design)
* The nominal capacity of a battery indicates the amount of energy it can store under ideal laboratory conditions. This value is measured at a constant temperature and under defined conditions in order to create a reliable reference for the performance of the battery. These stringent test conditions cannot be met with commercially available test devices.
