The battery replacement process is extremely poorly designed. The screws are too small, they are not on the side to prevent the battery from falling out, the gasket never seats correctly, and overall a terrible design.
And now it’s broken. As I anticipated, ordering a new unit is the only way
I would request a free replacement and see what they say. The cost to you of making that request is pretty small and worst case is they say no.
Having two of these and seeing your post, I decided to open one. The gasket presses into a channel which then holds it in place. The battery similarly clips into its location. If either falls out when you invert their half of the click then they weren’t properly positioned and should be pressed back into place.
The only thing I found was that the two halves only join in one particular orientation. In any of the other 3 you might try, the screws might seem too short and you could potentially crush one of the battery contacts.
And yes, mine worked just fine after reassembly.
Mark, I worked in this for over 90 minutes before it broke. The battery did not clip in and in fact the terminal off the side impeded it from staying in place. I put tape in the back of the battery (+ side) not in contact with the nodes and it still wouldn’t stay in place. The gasket was an issue when trying to put the screws back into the unit it always shifted and wouldn’t allow the screws to be inserted.
There are at least two designs, the first one I disassembled/reassembled has black buttons.
In view of your response I did the same with the one I have with blue/orange buttons which I think is newer. You are correct that the battery is not retained on this design, but the gasket still is when put into its groove. On the newer design the screws are also retained - you have to do extra (unnecessary) work to fully remove them. And like the other design, the two halves only reattach correctly in one orientation.
Bad design? No, pretty standard. Much better than some (older Garmin heart-rate monitors). Infinitely better than some GPS units I’ve replaced batteries on (though those are shamefully not designed to be user repairable). The only aspect I would fault is that single orientation feature when it would have been easy to have 4 gaps in the moulding surrounding the battery.
And yes, once again the Click reassembled and worked fine afterwards. The only issue I have is that you can only pair one with Zwift at any time
I ordered a new one so hopefully the new one will be easier to change when the time comes. A better design would make it be rechargeable like the heart rate monitors. If its achievable for that device this one should work too
