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.
