Well, finally I achieved full draining my RM2, so I started charging from an “out of battery” screen.

Remarkable usually tells you to charge from an USB laptop port or something similar to make a slow charge. I used a low Amps power source (300 mA maximum I think), so once plugged in it tried to start 2-3 times before staying off.

I don’t know how much capacity the battery has, so I’ve used an USB power meter to make the measurement.

The issue comes here: At 80% with 1836 mAmps fitted into the battery. The charging process stoped. It didn’t make difference to power it on. It make a little power compsumtion (wifi connecting and so), but it didn’t get an steady power level that indicated it was really charging.

Second picture: So, I changed to a 2 amps power source and it continued charging with near 1Amp power.

Third and last picture: Finally it got full charged (up to 100%) with a final 2490 mAh capacity (aprox). Take in count that when the tablet powered off because “ran out” of battery, doesn’t mean it was full depleted to death. So we can figure the battery has a 2500 mAh capacity.

​

Really weird about why it stopped at 80%.

And I can tell now that I’ve never seen before that the battery drained so fast before while using it, as some others say.
