Closed lead-acid batteries

Closed lead-acid batteries are absolutely reliable energy suppliers with a long service life and maximum reliability, even for critical applications. The batteries with liquid electrolyte consist of positive tubular plates and negative grid plates. They are ideally suited for applications with high cyclic and capacitive loads, such as power supply systems, safety power supplies according to VDE 0100-710 and VDE 0100-718, telecommunications equipment or as storage for regenerative energies.
