  2. Topics • Life expectancy • Outside cabinets • Temperatures • Maintenance • Alexis Ni-MH Batteries • Battery Monitoring Maintenance Communications Systems

  3. 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.

  4. 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.

  5. 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.

  6. 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.

  7. 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.

  8. 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.

  9. 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.

  10. 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.

  11. 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)”

  12. 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.

  13. Ni-MH Battery 30Ah/24V60Ah/12V Special Features: Ni-MH battery 100% environment protection Cells UL 1642 Listed E#MH29437 Warranty: Eight year full replacement: Four year limited replacement after eight. Year 1 80% replacement value Year 2 60% replacement value Year 3 40% replacement value Year 4 20% replacement value Warranty subject to conditions outlined in warranty documentation.

  14. 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.

  15. 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.
