How Often Should You Replace Dog Collar or Fence Batteries?

There are a number of factors that can influence the lifespan of your system’s battery:

  • How often does the collar get activated? – If the collar needs to warn your pet frequently, the battery will drain more quickly.
  • What setting is the collar set at? – For bigger dogs or pets that need stronger warnings, the extra power will drain your battery faster.
  • What kind of climate do you live in? – If you live in an area that is commonly exposed to extreme temperatures, you’ll likely get less performance from your battery.
