DIY - Replace The Battery in a Dog Collar

This has absolutely nothing to do with anything on this blog. I just like showing people ways to save money. Plus I hate it when companies design things solely for the purpose of taking your money. So here I will show you how to save money by deconstructing an unnecessary battery pack that was designed for one purpose, to take your hard earned money. There is NO reason to design something like this other than greed. They could have just as easily designed it to easily replace each battery inside the pack. In fact, they recently came out with their new pack, in which this can be done. But now you have to buy the new pack, and at a much higher price. This should have been done with the original purchase, but they wanted to sell you something "new" at a later date. These greedy pigs deserve no more of our money. Anyway, enough with the ranting.


If you have ever purchased an electronic dog collar for training purposes or maybe for excessive barking, then you know that replacing the battery is expensive. Instead of paying $25 plus shipping you can do it for about $3 and 15 minutes of your time.

I am one of those who likes to know how things work. The last time I had to replace my dog's training collar battery, I decided, since I was just going to throw it away, I might as well take it apart and see what is inside. To my surprise, this is what I found...

Yes, that is right, two common CR2032 watch batteries. Well, happy to see this, I picked up a couple for $3 at Wal-Mart, put it back together and saved the other $25, I was going to spend, for a rainy day.

Here is the quick DIY procedure for replacing these.

1. Remove the upper plastic surrounding the batteries using some clippers and a sharp utility knife. Remove the old batteries. Be careful not to damage the metal contact. If you can, leave a little bit of a lip so that when you put in the new batteries they won't fall out easily. They wont fall out easily anyway because the housing is so tight, but it just adds a little more protection.

2. Make sure the contact is in place as shown above, then put in just one of the new batteries, positive side down and against the metal contact. Press down firmly. Then place a small piece of aluminum foil, folded so that it is doubled, on top of the battery, as shown below in the second image.

3. Put the second battery on top of the first, negative side up, positive side against the foil and the other battery. Make sure the foil is centered properly before you put it in. You don't want it touching anything but the two batteries.

4. Cut a small piece of rubber band to fit in the gap between the battery and the metal contact.


5. Carefully place the battery pack back into the collar. Test the collar to make sure it works. And if all went well, it should.

You just saved about $25
