PCB protected lithium-ion battery with a possible 15A discharge current as well as components of the highest quality standard fused by Keeppower into a performance battery. A 15A discharge current, a capacity of 2600 mAh, a Japanese cell and IC make the R-series an all-rounder. Sony Konion (US18650VTC5) was used as the cell, and quality components from Seiko were used for the PCB.
Equipped with Seiko (Made in Japan). Protection/PCB with short circuit, overcharge and deep discharge protection, this is suitable for just about all torches. The Keeppower 18650 batteries are especially recommended for torches, LEDs, mech. battery carriers, as well as all applications where high safety and high performance are required.
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 18650 cell without PCB.
Please note that removing or damaging the protective electronics (PCB) may result in 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.
