I've seen many post, but no answers? Surface Pro Classic and just bought a Power Cover. Power Cover is recognized as both a keyboard and a battery under devises. All firmware ever pushed is there and updated. Battery #1 and Battery #2 show in the battery menu...but not charging or maybe 100% charged is completely depleted.
Once the internal battery reaches 80% (or so) the Power Cover charge goes from 0% to 100% and not charging. Once the internal battery is depleted, the Surface shuts off and the Power Cover sits there happily doing nothing to help.
Has Microsoft just ignored the many people that this problem has occurred to, or is there not a fix. I'm trying to hold out till the Surface Go, but this battery thing is annoying to deal with.
Please don't add the gif. of how the batteries charge or how the blue fills the keyboard and monitor, please please don't answer with that.

Thank you so much, Pete.
I disassembled a 500ma 4.2v 18650 charger. It was a few more milliamps than you used, but it's what I had on hand...
These surface pro battery covers are currently 30 bucks on amazon, likely because they are almost all broken - after much fury, I'm happy to have tried this. I left my surface at work, but I'm hoping if 3v holds for an hour it holds for half a day.
how much of current and voltage you applied on each cell to boost the voltage?
is there anyway for a newbie to achieve this? i really need my new power cover for my long flight back home. i am comfortable with electronic stuff.

Thank you for helpful information.
I bought one from Amazon, while it is brand new but not chargeable. Following your instruction I was able to revive it.
