OGi Bloc Batteries
(according to VDE 0100 part 710 & 7108 according to DIN 6280 Teil 13 – formerly VDE 0107/0108)
Emergency starter batteries supply the starter with energy. These are so-called OGi (surface-lead batteries), which are prescribed according to VDE 0100 part 710/0108. The starting current for the starter is provided by OGi Bloc starter batteries. These also ensure that the most important monitoring functions of the power generator remain active even in a voltage-free state.
The WA Notstromtechnik GmbH OGi bloc batteries are sturdy, optimized for high discharge power lead-acid batteries, particularly suitable for bridging times of a few seconds up to one hour.
They are used as starter batteries for uninterruptible power supplies (UPS) of emergency generators, auxiliary power supply of data and signal systems of transport systems, switchgears of utilities and other equipment.
