Overview
A 2-volt 125Ah cell is the building block used to construct the
Enhanced VR Series family of batteries. These modules may be
mounted in a variety of ways to meet individual customer needs.
The valve-regulated design and construction of the Enhanced
VR Series batteries prevents electrolyte leakage and minimizes
water loss and maintenance throughout the design life. During
normal operation, oxygen is generated at the positive electrode
and hydrogen is generated at the negative electrode. In
conventional (flooded) lead-acid cells, these electrochemical
reactions result in water loss from the electrolyte. The
self-resealing pressure release safety valves in Enhanced VR
Series batteries are designed to aid in the electrochemical
recombination of nearly all the oxygen within the battery. In
addition, the safety valves prevent the build-up of excessive
internal pressure.
Like other Lucent Technologies valve-regulated batteries, the
Enhanced VR batteries’ pure lead positive grid is the key to a
slow, uniform growth rate that promotes longer life. This slow
growth rate, combined with extremely low water loss, allows the
cell to maintain capacity over its 20-year design life at room
temperature operation.
The Enhanced VR batteries are ideal for most operating
environments because of its leakproof seals, high-strength,
flame-resistant PPO/PS jar and cover, low gassing rate, and high
energy density. The patented metal sleeves improve heat
dissipation and add dimensional support to the battery at the
higher operating temperatures.
The Enhanced VR Series batteries comply with the requirement
for sealed battery/cell pressure release test of UL924, Standard
