If this really pass, they will have to change the design

The problem isn’t that the battery is glued in. It’s quite easy to remove. The problem is that the connector was fastened with glue inside. I would be very surprised if there is a way to separate it, at least without knowing what type of glue was used to select a suitable solvent.

If you look at the photos in this document (https://fccid.io/2ACAHAC01/Internal-Photos/Internal-Photos-3615016.pdf20), when the ConnectClip was being certified, the connector was ripped off the PCB.

They don’t have to redesign it. They just have to stop using glue on the connector. Aside from the glue, it would be relatively easy to replace the battery.

Thanks for sharing this video. It’s more work than I expected with having to widen the slot by a bit to fit in a wider battery profile. But it’s very helpful.

With the first battery my wife found on eBay, she also had to widen the space for the battery. The second time around, she found one that fit better, and might have fit in the original space.
