Sportdog 425/825 charger

Posted by JR on 8th Feb 2022

I ordered this product from Petsandbeyond because the tips of my old SD-425 charger wore out and fit loosely in the sockets of the collar and transmitter. The devices were not charging and I began to wonder if the batteries had failed. Instead of replacing the batteries, I ordered this charger from petsandbeyond and was pleased to see that it is the same quality, or maybe even a little bit better quality, than the original charger that shipped with the 425 collar I bought years ago. The tips on my the new SD-425/825 charger fit snuggly into the sockets, and now the collar and transmitter properly take a charge. If your 425/825's are not charging properly, it could be that you need to buy one of these chargers, like I did. I'm a happy customer; time to go work with Rosie, our Blue Heeler.
