Another tidbit of information I just learned while replacing the batteries in my Dad's sensors..... before you glue the top back on, make sure and bend the top contact a little. That way when the top is on, it presses the contact onto the battery. I did not do that on one of my Dad's, and the next day, the monitor would not pick up the sensor. I took it apart and saw the top contact had no bend in it and figured it just wasn't making contact with the battery. I bent the contact into a U-shape and glued the top back on. Now it works perfectly.
Another thing I found....
The batteries have about 3.2v when they are new. When they need replacing, they are only down to 2.85 volts. I realize the electronics need a certain voltage to operate, but I was a little surprised to see how little the voltage had to drop before they sensor was inoperable.
In either case, I've done this to several sensors now, and they all work great. The most important part is to not lift the battery up any further than absolutely necessary to get a knife under it to break loose the bottom tab. Just a rich too high, and you will break the bottom contact of at the soldering point.
A close second is just to put an insulating piece of plastic under the battery.
Once you get the original battery out, the rest of the battery replacements will be super easy since the battery is just setting in there.
No more buying replacement sensors !!!!
