SAFT VNT DU HC 1-003 NEW.pdf - CAB Special Batteries

High Temperature Series
Nickel-Cadmium
VNT D U HC
The new VNT U series benefits
from the latest innovation on
Saft’s PNE (plastic bonded nickel
electrode) technology. The VNT U
series operates until + 55°C but
also brings an improvement at
low temperature, suiting perfectly
with severe outdoor applications.
VNT D U HC is specially designed
to accept a permanent charge
in high temperature environment
such as emergency lighting
equipment. VNT D U HC offers
at least 4 years of life duration
at an average temperature up to
+ 55°C in accordance to the IEC
61951-1 standard (U type cells).
VNT D U HC is ICEL 1010
registered for + 55°C applications.
To meet customers’ requirements,
Saft provides custom-designed
and standardized battery packs.
For your battery design and
system needs, please contact
Saft’s engineers.
