For a long time, Li-ion batteries in special sizes have been neglected by development due to low demand. Now, the technological progress has taken place in the special size as well. Keeppower presents after successful market placement of 18350 Li-Ion battery with 1200mAh now also a battery in size 18350 with 1400mAh.
Protection/PCB with short circuit, overcharge and deep discharge protection. Seiko (Made in Japan). Designed for: Torches, LEDs, etc.
Not suitable for e-cig battery carriers and nominal operation. Please also note the recommended constant discharge current.
Please note the dimensions of the cell before buying! Due to the built-in electronics, the cell is not suitable for every application!
Height and diameter are larger than a standard 18350 cell without PCB.
1 piece Keeppower 18350
When ordering two batteries, a battery protection box is supplied free of charge.
Important: Only use this 3.7 volt Li-Ion battery in devices that are also expressly suitable and approved for the use of 3.6 – 3.7 volt Li-Ion batteries.
Please note that removing or damaging the protective electronics (PCB) can lead to a short circuit, 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.

Notes:
A special charger is required for charging lithium-ion batteries, which 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.
