Alpha's battery heater mats are designed with safety and effi ciency in mind. Alpha's battery heater mats are a low-cost way of keeping backup batteries operating at their optimal temperature, maintaining battery backup performance at >70% of nominal levels at temperatures below 32°F/0°C. The heater mats' insulated bottoms ensure that energy is directed to the batteries and not wasted heating the enclosure. Their durable polyester outer shells protect the heating elements from damage; their redundant thermal control protection ensures against overheating; and their fused power input protects against shorts. Alpha battery heater mats are a smart addition to any backup power system.

  • Durable polyester construction
  • Sealed on-mat electronics for maximum protection
  • On-mat thermal switch and thermal fuse for redundant safety
  • Insulated design directs heat to the batteries not the enclosure for a 30%
  • reduction in power consumption
  • Piggyback plug standard on 120V models

Technische Spezifikationen
VRLA Battery Efficiency VS Temperature and Discharge Rate 
Battery performance is set for a normal room ambient temperature of 25°C/77°F. In outdoor installations, as temperatures drop the batteries lose the ability to perform the chemical reactions necessary to provide backup. For example, a battery string that provides 2 hours backup at room temperatures will only provide 1 hr 36 min (80%) backup at 0°C/32°F. As temperatures approach –40°C the chemical reaction virtually ceases and no backup can be expected. Battery heater mats are low-wattage heating pads designed to keep the core battery temperature at a level that will maintain at least 70% capacity at -30°C. Battery heater mats maintain battery backup performance in areas where lower temperatures are common.
