Accucell 6 - measure Lixxx internal resistance

Hi,

I just got an Accucell 6 this week, and noticed that it has a function to test internal Lixxx internal resistance. I saw this video:

that shows it working.

However, when I tested with several of my batteries, after the test, it just shows all dashes instead of 2 rows with numbers, i.e., I get:

1: —— —— —— mOhm
4: —— —— —— mOhm

instead of 2 rows with 3 numbers in each row, as shown in that video.

Does anyone know why this would be the case?

Thanks,
Jim

Could it be because you aren’t using the balance port?

The internal resistance measurement feature is like a beta since not all Accucel-6 chargers come with that feature. It’s a hit or miss when getting one. I unfortunately got one without IR measurement.

Hi,

It could be. As I said, I’m pretty new to this. The batteries were only connected with the “normal” red/black (positive/negative) cables. Actually, I don’t even know what a “balance port” is :)…

If you still want to go through the hassle of connecting all the wires and maybe even some soldering, refer to the diagram here:

Hi,

I re-watched the video, and it does look like he had the cable connection that I have, plus another cable going to the side connector on the Accucell 6, so I think that you’re right.

I’ll check what you linked.

Thanks,
Jim

Hi,

I just checked your diagram, and that’s with 3 cells. I’m guessing it may not be possible with just one battery/cell like I have.

Also, the paper that came with the Accucell said something about the measurement being “relative”. I guess that what they meant was relative between the more than 1 cell/battery :(…

Thanks,
Jim

There have been some members who have soldered wires to magnets and created a series charging setup with multiple cells. From personal experience, it’s not worth it. :cowboy_hat_face:

Not sure what they mean by relative either.

Not brave enough to do that yet… still taking “baby steps” :)…

I’m guessing that what they mean by “relative” is the resistances that it measures/shows are relative between more than 1 cell, i.e., not an absolute impedance/ohm reading.
