Yes, just a tiny bit...but if your battery is low it will move to charge until the battery is normal. It will also move further in the discharge position when discharging.
I may have a solution. I had a volt gauge I forgot about. I tore the guts out, took the face off, swapped the face on from another amp gauge and glued the orange pointer on top of the volt gauge pointer. I just need to work out installing it into the cluster and wire it in. I'll go straight to the back of the fuse panel to the "acc" side so it's only hot with the key on and ground the other side. I'll go get pics of where I am now. That way, I can go ahead and just remove the amp gauge and bypass it altogether.
