The system’s battery life has decreased. I have to charge it more often.

For our systems with Nickel-metal hydride (NiMH) batteries, the battery life in between charges is approximately 40-60 hours for the Transmitter and 40 hours for the Collar Receiver, depending upon use.

  • The rechargeable Nickel-metal hydride (NiMH) batteries are not memory sensitive and do not require depletion before charging. Batteries should never be removed from the battery compartment for charging.
  • The batteries come partially charged from the factory, but will require a full charge before the first use (24 hours).
  • When storing the unit for long periods, remember to regularly give batteries a full charge (12 hours). This should be done once every 4 to 6 weeks.
  • To maximize battery life, after initial charge, it is not recommended to leave the battery plugged in for more than 12 hours.
  • If your equipment has not been charged for an extended period, you may experience a decrease in battery life the first few uses. Afterwards, the battery life will return to previous capacity levels.
  • You should expect hundreds of recharge cycles from your batteries. However, all rechargeable batteries lose capacity over time relative to the number of recharge cycles they experience. This is normal. If your operating time drops to half of the original life, contact the Customer Care Center to purchase a new battery.
  • The batteries should last for a period of 3-5 years. When a battery needs replacement, you can order a new pack by calling our Customer Care Center at 1-800-732-0144, or by visiting our website at Please do not open the Collar Receiver or Remote Transmitter until you have received the replacement.
