Yes. The crucial bit that I missed (or misinterpreted) was that it doesn’t “reverse the polarity”. Once you mentioned that (and I subsequently observed for myself) it became clear. 🤦‍♂️ ---

> [@gwydion](#): > > Putting it in backwards will cause both positive and ground terminals to make contact with the larger positive surface of the coin battery, while the negative surface is isolated. That connection would short circuit positive and ground on the PCB and potentially (pun intended) allow capacitors to discharge and should not generate too much heat if they are small caps. This is how a smarter person than I intelligently describes what I was poorly attempting to say! ---

The funny thing here is that I, not being a botanist, used the term “polarity” rather than just saying “put the battery in the other way around.” This was all rather amusing though and I’m glad to see apologies made. This really is a great community. ---

I have a few years on you as a computer engineer, but that doesn’t mean much. For some strange reason, surface mounted capacitors can and do accumulate a ‘static’ charge and the only way to remove it is to short out the capacitor’s charging circuitry. That’s what “grounding” out the battery terminals appears to accomplish. In any case, it’s the second thing recommended. The first is to remove the battery for about five minutes. ---

You have my sympathy @titanicus, as another “professionally qualified electronic engineer” I also interpreted “putting the battery in upside down” as reversing the polarity and got quite head scratchy for a bit there (even though I defected to digital 0’s and 1’s as soon as I graduated 30+ years ago so not a lot analog in my head to get scratched). Electronic design v mechanical design, eh, proper mind fudge, glad I’m retired… and have a Garmin HR monitor 😉 ---

Pictured is my high tech engineering solution, for which I needed all my skills as an experienced electrical engineer. And…that works. So clearly something wrong with the battery cover and/or seal. But hey, it’s only my third Tickr X this year. ---

Funny you should mention the battery cover. I had this happen to my Tickr Battery cover: Seems one of the tabs was broken completely, another was half broken and the third was fine. I reached out to Wahoo CS and they sent me a replacement (Tickr that is, not just the cover) 🙂 ![IMG_5063](https://us1.discourse-cdn.com/flex020/uploads/thesufferfest/original/3X/9/4/94fa4f8fb43deae6447859efed82fe4b7cdccd81.jpeg) Edit: I’ll have to try the duct tape solution as a back up should anything go wrong with the new one 👍 ---

I had exactly the same experience with Tickr X number 2 🙂 Battery tab broken, Wahoo sent a completely new unit as replacement. Great customer service, but an improved battery cover design would be even better… [Previous page](https://wahoox.forum.wahoofitness.com/t/wahoo-tickr-x-suddenly-inverts-readings/23033.md?page=1)
