is there something wrong with my Opus?

[Shawnturner]

Hi all.

Pretty new to things. Bought 8 used laptop batteries off eBay, 9 cell 7800mAH so 2600mAH each cell when new. The guy said if I want he has lots more of these packs.

So I broke open the first few packs and cleaned up the cells.

They all read 3.68v on my DMM which I think is a good thing, correct?

Next thing I did is throw the first four on my shiny new Opus BTC-3100 v2.2 to charge them up. It stopped at 4.17-4.18, which I though was a little weird – shouldn’t it be 4.2?

Then more weirdness, I took the cells out of the Opus and checked them with my DMM and they read 4.47-4.48v!! Yikes! Pop them back in to the Opus and it shows them at 4.17-4.18!!

Any idea what is going on?

Do I have a bad Opus?

Do I have a bad DMM?

Is this normal behaviour?

Please help.
Thanks!

I didn’t find the right solution from the Internet.
