(near Stockholm) It is extremely likely that there are two Lithium 18650 standard cells in the GPS tracker.

    They have a higher energy density than flat polymer batteries based on LiIo.

    Luckily, my GPS trackers are a bit older, so I can’t open them destructively.

    And, of course 😅, I have separate charging electronics for 3.6 volt lithium batteries with me.

    Tralla…

    So re-solder, charge and re-solder again. Then assemble everything.
