High-quality Sanyo cell with long service life and high cycle stability. One of the most powerful 16650 battery cells serves as the cell for the 16650. The diameter is just under 17 mm, so Keeppower 16650 batteries can also be used as 17650 or 17670 batteries. The Keeppower 16650 battery can therefore replace two 16340 or LIR123A batteries in many applications with a capacity advantage.

Keeppower 16650 or 17650 Li-Ion battery protected (positive terminal raised)

Protection/PCB Seiko (Made in Japan) with short circuit, overcharge and deep discharge protection ensures safety in use.
Designed for torches, LEDs, battery carriers, etc.

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 16650 cell without PCB.

Safety notice:

Please note that removing or damaging the protective electronics (PCB) may cause a short circuit, fire or explosion.

Further characteristics:

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.

Note:

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.
