VARTA bloc range
Vb 12142...Vb 12149, enhanced power

Application Installation
VARTA bloc batteries are designed for universal use where high safety requirements apply. They are qualified for short discharge periods at high current and for capacitive discharge over longer periods.
Their fields of application are reserve power supply systems in power stations, nuclear power stations, sub stations, UPS and industrial systems, emergency power supply systems, engine starting and energy storage in solar power systems, according to national and international standards.

All standard types of installation are permitted. Due to the improved energy density the required area for installation is reduced. When installing in battery rooms the safety provisions specified in national or international standards must be observed.
