Vb
Battery Range Summary
PowerSafe® Vb batteries are vented lead-acid batteries designed for
industrial applications in power supply with high safety requirements.
These single cells are qualified for both short duration discharges
with high current and long duration discharges with low current.
The main areas of application are DC power supply systems in
power stations and substations, UPS systems, industrial systems
and emergency power supply systems. They can also be used for
engine starting and for energy storage in solar power systems.
The special rod plate design of PowerSafe Vb batteries offers a high
energy density and a very long life time in one unique design.
This gives better performance and can minimise the use of valuable
floor space. A rigid earthquake-proof cell allied with the unique
PowerSafe Vb safety pole terminals makes this a superior battery
design. A very long topping up interval minimises service
requirements to complete the package.
