If the range of your training devices are getting shorter over time, it's time to replace the battery. You can find batteries for Kinetic dog collar Transmitters and Receivers here.
Which Battery do I Need?
Pay close attention to both the model our battery replaces as well as whether you are looking for the transmitter or the receiver. The transmitter is what the owner holds to initiate a shock to the dog's collar. The receiver is the piece on the collar itself that actually delivers the shock. Each of our pages specifies which part the battery will fit and also directs you to the matching battery for the other half. For example, the transmitter DC-16 directs to the respective receiver DC-17.
Take a look at the options below, or check out the battery finder. This allows you to search by battery brand rather than the brand of training collars. BIAF offers only excellent quality batteries, equivalent to the original.
