this process.
And if suddenly someone has some interesting documentation for these types of batteries, I'll forgive you to share it :)

Answer 1

Most batteries have only two + and - contacts.
Try to determine the type by the characteristics that can be removed from them (details are in Google and Yandex), for example, by voltage, and everything will become clear.

Answer 2

Tell me more about the task. And it may turn out that it is easier to read the marking, for example.
