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 SystemsFeatures: Short circuit, overcharge discharge, and temperature protection. Load balancing between cells. Self cycling for high rate capacity and long life. Eliminates costly maintenance expenses.
