Received the Pocket 2 battery in Moscow 77 days after it was shipped, which I guess is predictable, given what I heard about Li-polymer batteries being prohibited in air mail. My Pocket 2 had stopped working from battery or charging it (kept at 0% saying it's "not charging"), and the replacement fixed the problem. Many thanks!
Installed it easily in my GPD Pocket 2. Seems to work fine, capacity reported properly on HWmonitor. Hopefully it’ll last for a long term.
