820-01521-A charges battery, does not show that it's charging

[2informaticos]

First of all, welcome to the forum!

When the battery is really charging, PPBUS_G3H MUST slowly increase, according with battery charge level.
If D6959 lights on battery alone, you should press SW6955 until LED goes off, before disconnecting the battery.

I recommend you to test first with a known good working battery.
Be aware of chinese crappy battery.
