Application

Valve regulated VARTA bloc batteries (VbV) are maintenance
free lead-acid batteries. The electrolyte is fixed as a gel. They
have been designed for a long service life and for reserve
power supply systems with high safety requirements, space
saving installation and maintenance-free operation. They can
be used universally both for capacitive discharge over a period
of hours and for short discharge periods of certain minutes.
They are used as reserve power supplies in power stations,
substations, information technology equipment, UPS systems,
for automation and traffic technology, and for emergency
power supply systems.

Construction

Positive Electrode Rod plate with

VARTA-calcium-tin-alloy

Negative Electrode Grid plate with calcium alloy
Separation Micro-porous separator
Casing Material Acrylonitrile-butadiene-styrene

(ABS), impact resistant,
optional: flame retardant
(FV 0)

Electrolyte Dilute sulphuric acid

Fixed as a gel

Terminal Design Leakproof safety pole rein-

forced with brass insert, M8

Connectors Solid copper (20 x 3 mm),

insulated, bolt-on type

Cell Valve Safety valve with flame arrestor
Charging Float charge voltage:

2.23 volts/cell at 20oC

Temperature Range -10o…+45oC

(Preferred value 20oC)

Installation

VARTA valve regulated lead-acid batteries are mounted on
insulated racks in upright position as a standard or built into
battery cabinets. For space saving installation it is possible
to install them horizontally (plates must be in vertical position).
For use in earthquake zones special approved rack design is
available. The safety provisions of the national and
international standards must be observed.

Features

• 4V / 6V / 12V bloc batteries

• Maintenance-free operation throughout its service life

due to valve regulated construction.
The electrolyte is fixed as a gel.

• Leakproof VARTA Safety Pole design

• Long service life due to VARTA Rod Plate technology

in accordance with EUROBAT guide: 10+ years

• Space-saving installation due to high energy and
power densities

• Low ventilation requirement, using the reduction
factors

• VARTA VbV batteries comply with the international
Standard IEC 896-2
