Power supply units with integrated energy store

While power supply units with integrated batteries (e.g. PSU713 BP ) are intended for single use and must be disposed of accordingly after depletion, power supply units with integrated rechargeable batteries (e.g. PSU413D+ AP ) can be recharged and used again and again. However, the service life of rechargeable batteries is not indefinite. In addition to regular servicing and maintenance, its service life is also dependent on the frequency of use and the operating and storage conditions.
