AlphaCell 3.5 and 4.0HP

Pure Lead Top Terminal Batteries
alphacell-35-and-40hp
  • Class leading batteries featuring pure lead technology providing up to 20% increased life expectancy
  • 3 to 5 times longer shelf life versus standard VRLA batteries
  • Up to 50% increased runtime in cold climates
  • Non-spillable UN2800 rating for ease of transportation
  • Higher runtime allows string count reduction
  • 5-year full, hassle-free warranty

AlphaCell HP Pure lead AGM batteries provide high power density and extended reliability for broadband applications. AlphaCell batteries enable using fewer strings in power systems compared to standard batteries while maintaining network runtime and reliability. For power supply loads that are less than 8 amps, 4 hours runtime can be achieved using a single string of AlphaCell 4.0 HP batteries, compared to using two strings of competitive products. Additionally, AlphaCell HP batteries provide up to 50% more runtime in colder climates compared to standard batteries.
