Life Expectancy
The life expectancy of lead acid batteries is 12
to 72 months in exposed metal cabinets.
They require site maintenance.
As communication networks evolve, Nickel
Metal Hydride (NiMH) batteries will provide:
Long lasting back up power (up to 15 years)
Improve performance in varied environments
Capital savings, expense savings , improve
customer service.
Reliability against battery failure.
Outside Cabinets
Equipment installed in outside cabinets for
the purpose of reducing loop lengths to
customers.
Having shorter loop lengths brings less
attenuation, higher bandwidth speeds, better
service.
Basic telephone service must work in event of
commercial power outages.
Outside Cabinets
The initial installations used Sealed Lead Acid
(SLA) batteries.
Today they have Valve Regulated Lead Acid
(VRLA) batteries.
SLA and VRLA generic terms that describe the
battery construction.
Temperatures
Internal temperatures in a
cabinet can reach120°F or
higher.
SLA nor VRLA are not capable of
withstanding extreme
temperatures for long periods of
time.
Extreme temperatures shorten
Lead Acid batteries life
expectancy and increases
outages due to battery failure.
Temperatures
VRLA manufactures promote a
ten year life expectancy but
only if maintained at 65°F to
75°F.
Through out the continental US
cabinets will experience
temperatures far above 80°F.
Maintenance
SLA and VRLA batteries were assumed to
require no maintenance, however they
should be tested under load at least twice a
year.
Estimated time for a technician to perform
warranty maintenance is four hours per site.
Technician loaded labor rate may reach
$117.75 per hour.
Twice a year would cost $942 per site.
Maintenance
For a company with 4,000 remote sites in the
US, minimum maintenance cost could be
$37,680,000 over a ten year period .
An excerpt from one manufactures warranty.."If
ambient temp is 80°F to 90°F then warranty
period is two years only. No warranty will be in
effect with temps over 90°F."
For cabinet temperatures reaching 120°F.
Battery life span 3.5 to 3.6 years.
Maintenance
The average loaded cost is $3,085.30 for
48v60a systems.
For a ten year period $8,814.70 .
Should the inside cabinet exceed 120°F, the
average life span is 2.0 to 2.5 years. At an
average loaded cost of $3,624.10 for a
48v60A system.
For a ten year period cost could range from
$13,938.29 to $18,120.50.
Alexis Ni-MH Batteries
Function in all environments, regardless of
their exposure to extreme temperatures,
warranted to operate from -13°F to 167°F.
Warranty covers full eight years with four
additional years of pro-rated warranty.
No reference to maintaining required
temperatures.
No field maintenance once installed with our
“Battery Monitoring & Maintenance
Communication System
(BMMCS)”
Alexis Ni-MH Batteries
No hazardous materials and 100% recyclable.
Our batteries have integrated processing,
monitoring capability.
Give the end-user the reliability of knowing
when battery is functioning correctly or
incorrectly without dispatching or sending a
technician.
Provides online critical data including how
many hours of backup power remain at
current draw, when using
the BMMCS.

BMMCS
Battery Monitoring Maintenance
Communication Systems (BMMCS).
It allows the key battery data to be accessed
locally or remotely.
The end-user will be able to access data from
each individual battery at a remote site.
The BMMCS unit will also provide alarm
signaling for rectifier unit fault and battery
array fault.
Battery Monitoring Maintenance Communications Systems
Features: Short circuit, overcharge discharge, and temperature
protection. Load balancing between cells. Self cycling for high rate
capacity and long life. Eliminates costly maintenance expenses.
