Hello, I have recently received my Opus BC3100 v2.2 charger, and I promptly proceeded to test it. First, I inserted a just-received Eastshine E35U and the charger immediately came to life, and started charging it. I was able to do everything the manual says it can do (e.g. change the current, etc.). I am now running a "TEST CHARGE" cycle to see how much this battery can hold.
I then tried some new-but-not-used-for-a-year Panasonic 18650s, and the Opus charger would not "detect" them. It would show "null" on the display. I waited. I switched slots. I switched batteries (I have several of these Panasonics). All to no avail. Always "null".
So then I put these Panasonics on my XTAR VC2 charger, and it immediately showed near 0V and started charging. Those are up to 1155 mAh (and climbing).
In other words, the batteries were drained pretty badly it seems. The Opus seems unable to do anything with them, while the XTAR seems to have no problem.
Am I doing something wrong?
Your help is much appreciated. Thanks.
