On the part of the manufacturers and media, there is rightly a warning for rechargeable batteries of technically inferior quality which in extreme cases can explode. Normally, it concerns products which for example do not have any protection against overcharging. For us it goes without saying that we only use the best storage cells so that our rechargeable batteries are not affected by these problems! All rechargeable batteries which we offer have first-class cells and additionally feature an automatic protection against overcharging and overheating.

From us you get: nickel-cadmium batteries (Ni-Cd), nickel-metal hydride batteries (Ni-MH), lithium-ion batteries (Li-Ion) and lithium-polymer batteries (Li-Polymer).

Furthermore, we would like to provide you with some interesting background information here:

Charging
Ni-MH batteries can be charged between 400x and 700x and Li-Ion as well as Li-Polymer batteries up to 1000x. Before every charging procedure Ni-MH batteries should be completely discharged. This is not necessary for Li-Ion and Li-Polymer batteries.

Disposal
Please dispose of used batteries as regulated by law. The disposal with household waste is strictly prohibited according to the Battery Act. Dispose of used batteries at local collection points or dispose of them free of charge on your local retail market. You can give back batteries/rechargeable batteries which you purchased from us after use to MEXXTRONICS, Daniel Beier, Voltastr. 77, 60486 Frankfurt / Main, Germany or return them to us by mail with sufficient postage.

Storage
Completely charge the rechargeable battery before storage without use. Recharging is required after 12 months at the latest due to self-discharge.

Increase life cycle
If you use simple tricks you will have more from your rechargeable battery. Discharge rechargeable batteries with long periods of operation at least twice a week and as a basic principle only charge when the device signalises you to do so.

Memory effect
The rechargeable battery remembers how often it has been used. If the rechargeable battery is not completely discharged before charging, small crystals form on the electrodes and reduce the possibility to absorb charging. So if you have not discharged your rechargeable battery several times in a row, the availability times will become shorter and shorter.

Milliampere hours (mAh)
Unit of measurement for the stored charge amount of electric energy. A rechargeable battery with 500 mAh give off 500 mA in one hour or 50 mA in ten hours at ideal temperature (approx. 20°C). The performance decreases significantly at temperatures over 30°C and under 15°C.

Cleaning
There should be an efficient current flow between the device and the rechargeable battery. Have the „contacts“ cleaned regularly.

Self-discharge
A rechargeable battery which is not in use loses its charge over a certain period of time due to self-discharge. Self-discharge is dependent on temperature and is larger at higher temperatures than it is at lower ones.

Overcharging
Overcharging leads to a reduction of the possibilities of absorption and can destroy the rechargeable battery. Good battery chargers switch to trickle charging after complete charging and therefore avoid overcharging. If this function is missing, the charged battery should be removed from the battery charger after complete charging and not remain there unnecessarily for a longer period of time.
