Replacement Batteries for Thingy52

[HeneryH]

I had like three Thingy52s for a project and have just come back to it after about a year.

The batteries are now dead and the device does NOT seem to want to charge.

All three batteries breaking seems suspicious but maybe they are so dead that the charging circuit does not work.

Are there any replacement LiPo batteries that can be used or does anyone have a suggestion for getting these three usd$50 devices back from the dead?

I see the LiPo is marked as LP803448 and will give a replacement a try.

Argh, it is a three-wire battery and not a two-wire battery.

I'm trying to "jump" the battery from a two-wire charger I have but peeling the insulation away and exposing the solder pads and then maintaining contact long enough with tiny spring clamps is a pita.

We'll see how it goes....
