First National Battery has launched a new range of commercial
vehicle batteries, to overcome the problem of vibrationinduced
failure in heavy duty applications. The batteries
are made in South Africa for locally specific conditions and
conform to IEC and DIN specifications.
Some of the factors that make them vibration proof include
that the plates are anchored to the bottom of the containers
using hot melt glue, and that the plate locks are fitted to the
end cells, eliminating the possibility of damage to inter-cell
connectors. At the same time, fully framed grids provide
superior strength, better conductivity and eliminate the possibility
of separators being pierced.
The new range is now made using silver calcium alloys that
result in additional benefits. These include: suitability for
diesel starting - even under the most trying conditions - with
increased cold cranking power; lower self discharge rates;
and suitability for parasitic loads, such as GPS and driver
comfort amenities. The new batteries’ flat lid design is in line
with international trends, and they boast flash arrestors for
improved safety.
They are ideally suited for long distance haulage, frequent
stop-start deliveries in urban areas and coaches and buses,
and are subject to and exceed SANS Battery Vibration test
60095 – 1: Rev 7. The latter requires the battery to withstand
vibration levels twice that of a passenger vehicle battery, for
four times longer.
