A battered Alpatronix iPhone XS Max wireless charging case emerged from the ground cover at the end of the driveway:

The iPhone was nowhere to be found, so harvesting its organs seemed appropriate:

I assume the four steel disks aligned the coil with the wireless charger.
A few hours of steady tension relieved enough of the sticky tape to release the battery:

Although its bag now sports a few wrinkles:

The alert reader will note the outside of case proudly proclaimed “Capacity: 5000 mAh” while the underside of the battery says “4920 mAh”, but that’s surely close enough for consumer electronics these days.
The battery charges through either the Qi coil or a (mercifully standard Micro-B) USB jack and everything seems to work.
Not sure what I’ll do with a bare lithium cell and its charger, but they ought to come in handy for something around here.
So people are now literally dropping off old batteries and chargers at your house? :-)
