Magnetized meter

You all keep describing moving coil meters for this/these "battery testers". This implies a high impedance meter.

An high impedance meter would be next to useless for testing a battery except to give a rough indication of its unloaded voltage output.

What is the part/model number of this device to see exactly what it is?

Mike-

It is not magnetized. Since you have shown that static electricity is not causing it, there are two other causes I can think of.

  1. It is a zero-center meter movement that is biased to one end of the scale when turned on and working.

  1. There are coil springs at both top and bottom of the meter shaft. These springs oppose each other. One of them is broken.
