Battery and accumulator

From a technical viewpoint, a battery is a combination of several similar galvanic cells/elements that are switched in series. There are batteries made of primary cells (non-rechargeable), and batteries made of secondary cells (rechargeable), also known as accumulators.

When a battery is charged, electrical energy is converted into chemical energy. When a load is connected to the battery, the chemical energy is converted back into electrical energy. The rated voltage typical for an electrochemical cell, the efficiency and the energy density all depend on the type of materials used.

If a battery remains unused, it loses a proportion of its stored energy over time. This process is called "self-discharge". The extent to which this occurs depends on the type of storage and the age of the battery.

The following batteries and accumulators are available:

• Rechargeable buffer battery
• Lithium batteries
• Main rechargeable battery

Note:

Accumulators are shipped with less than 30% of their maximum charging capacity to minimize risks during transport. A wide range of certificates¹⁾ are required for transport and import in some regions. These are available for download from our Customer Support. Before first use, accumulators should always be recharged, this also ensures the longest possible service life of the accumulators.

The device must not be disposed of in household waste (battery law, WEEE Directive).
