Battery Back Up Systems by Surefire Sentries


Stay warm with a battery back up for your pellet stove! Benefits of battery back ups:


  • Keep your stove running & avoid smoke backdraft when the power goes out!
  • You don't have to remember to recharge the battery, it's automatic!
  • Silent Operation
  • Easy to Install
  • If the power goes out, power will automatically transfer to your stove, even if you aren't there!



*Please be advised, some stoves require different battery types. If you are unsure, please consult your owner's manual as incorrect battery types may cause your stove to malfunction.
