information on Lucent Technologies’ 12IR125 and 12IR125LP
batteries.
Note: Except for specific references, the term “12IR125” refers
to both the 12IR125 and 12IR125LP batteries.
The 12IR125 battery is a 12-volt, stationary, valve-regulated,
rechargeable, lead-acid battery designed by Bell Laboratories,
an acknowledged leader in technology, research, and design of
power systems.
Lucent Technologies’ power products have proved their field
reliability by providing dependable standby reserve power for
the telecommunications industry for decades. All battery
components and manufacturing processes meet Lucent
Technologies’ strict specifications and quality standards.
Designed for applications where the loads are fairly large,
temperatures may vary, and long back-up time is desired,
12IR125 batteries are an excellent choice for Lucent
Technologies 60- and 80-Series cabinets, mini- and maxi-huts,
vaults, customer premises, and outdoor wireless communication
sites.

2 Product Description
Overview The 12IR125 is a 12-volt, 125 ampere-hour (ten-hour rate)
battery that packs greater capacity in a reduced footprint. The
compact design allows additional room for air flow between the
batteries or for an additional battery string in many applications.
The valve-regulated design and construction of the 12IR125
batteries prevent electrolyte leakage and minimize 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 12IR125 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
12IR125 battery’s pure lead positive grid is the key to its slow,
uniform growth rate, which promotes longer life. This slow
growth rate, combined with extremely low water loss, allowsthe
cell to maintain capacity over its 10-year life span (80% of
capacity @ 10 years) when operated at 77°F (25°C).
The 12IR125 battery is ideal for most operating environments
because of its leakproof seals, high-strength, flame-resistant
polypropylene (UL94 V-O) jar and cover, and low gassing rate
(compared to flooded design).
The 12IR125 battery complies with the requirement for sealed
battery/cell pressure release test of UL1989, Standard for
Standby Batteries.

Lucent Technologies 12IR125 Series II Batteries
2 - 2 Product Description Issue 7 December 1999
Features • Bell Laboratories’ patented lead/tin alloy post, leakproof
post seal, and valve-regulated design require minimal
maintenance.
• Post design:
– The 12IR125 has a dual-terminal post design (front and
side) that allows for flexible installation.
– The 12IR125LP has a front-terminal post design.
• Elongated slots on inter-battery bus bars allow for variable
spacing between batteries.
• Front-access terminals provide easy access to batteries in
cabinetized power applications.
• Cover:
– The 12IR125 has a top cover that protects from terminal
post shorting and includes a slot to hold a thermal probe.
– The 12IR125LP has a clear terminal shield that protects
the connections for the batteries, eliminating the need
for covers on the battery stand.
• Heat-sealed container and cover provide reliable seal.
• Flame-retardant, non-halogenated, polypropylene container
and cover meet UL 94 V-O and have an oxygen index
greater than 28.
• Permanent, patented V-O handle simplifies handling and
installation.
• Epoxy-coated jacket helps dissipate heat and provides
structural rigidity.
