SportDOG batteries last a long time, but not forever. We have SportDOG SD-400 rechargeable batteries and others for collars and transmitters.
SportDOG has stepped up to the plate with products that are powered by rechargeable batteries. Most people prefer batteries that can be recharged when it comes to pet electronic products, such as dog training collars, bark collars and invisible electric fences.
