Half the Price

The collars for our dogs for their invisible fence requires a battery plan - up till now.


The battery plan gives us two new "Power Cap" (i.e. proprietary) batteries four times a year or every three months, so for eight batteries it costs us $160.

A while back a friend found a site online that described "hacking" the batteries and making them your own. It sounded interesting and much cheaper, but I had just started a new subscription to the plan and had to wait.

The hacking is simple. The batteries are even simpler. The whole power cap thing is mostly a plastic housing with a CR1/3, 3 volt battery inside.

You simply cut open the plastic so you can reuse it (I wasn't very successful with the one)

Buy the battery at Radio Shack (nice slogan)

reassemble it and you're saving $80 a year. That's at least two cases of beer!

So the price of the battery at Radio Shack was a little more then I expected ($10), but there are places online selling the battery for a quarter of that price. Either way I'm saving $$ and not tying myself to some silly plan.
