Extended Battery Life For Greater Safety and Consistent Performance!
Both the R8 and R1200 Receivers deliver two-year battery life — eight times longer than the battery life of an Invisible Fence ® receiver! The less often you change batteries, the less likely your containment system will fail due to a loss of battery power. And there’s the added bonus of being more environmentally friendly — in 10 years, you’ll be using only five DogWatch batteries instead of 40 Invisible Fence ® batteries!
