Technical Specification for Stationary VLA - Cells

1. Application

BAE OGi - cells are suitable for safety batteries where operational safety and long operational life has top priority and high discharge currents during short discharge times and capacitive loads over longer discharge times are required.

They are used as standby source in power supply stations, transforming stations, UPS - stations, emergency light equipment acc. VDE 0108 and VDE 0107 and photovoltaic applications.

The round-grid plate used by BAE grant due to the high lead weight and the circular bars a long operational life and a very good high - current - performance. The straight - walled containers and the supported plates offer a high power - density related to the small foot-print. The transparent containers allows an all-round - control and they make service and maintenance easier.
