How does a battery work?

A rechargeable battery is a battery that consists of multiple, rechargeable cells. But how does this principle work? Moreover, what are the differences between various rechargeable battery technologies? You will find the answers to these questions here.

During charging, electrical energy is input into the battery. The energy input starts a chemical process.
Connecting a device (load) discharges the battery again. During discharge, the chemical process takes place in reverse and the stored energy is released again in the form of electrical energy.

STIHL cordless technology

Lithium-ion (Li-ion)

The significance of the lithium-ion technology used by STIHL and others continues to grow. This is because of the higher efficiency of the cell and the advantage that no memory effect occurs with this battery.

Other Battery Technologies

Nickel-cadmium (NiCd)
Cadmium (Cd) is harmful to the environment. For this reason, these batteries have been banned in the European Union since 2006. Only NiCd cells that have already been manufactured may be sold.

Nickel metal hydride (NiMH)
Nickel metal hydride batteries are common in the lower price segment. However, their performance is affected by the memory effect.
