Storage of batteries and accumulators - the best tips

If you do not want to use rechargeable batteries for a long time, you should store the energy storage correctly. We show you what to look out for.

Store batteries and accumulators correctly

A battery loses its lifespan with every charge, but it also ages over time. Wear cannot be prevented, but it can be reduced considerably.

The lifespan is shortened, especially at high temperatures. Therefore, store batteries and accumulators as cool as possible. Temperatures between 15 and 18 degrees are optimal.
If you want to store a lithium-ion battery for a longer time, charge it up to about 50 to 70 percent. If the battery is not used for several months, recharge it to 50 to 70 percent after a few weeks.
The optimal storage space is therefore in a cool and dry cellar. However, a drawer protected from light also does it if necessary.

Only the old nickel-cadmium batteries (NiCd) have the so-called memory effect, in which the battery remembers the current status. Whenever possible, these batteries should be fully charged and not discharged.
For several years now, you have only found lithium-ion batteries in almost all technical devices. These no longer have the memory effect.
If possible, do not store a battery in a damp room or even in the refrigerator. This does not damage the battery directly, but dangerous condensed water could form.
You should also be careful with the temperature. Minus temperatures are hardly tolerated by batteries, they overheat quickly when temperatures are too high.

In the next practical tip, we will show you how you can use a little trick to find out whether a battery is full or empty.
