I covered both sides with copper foil tape, soldered wires each side and reinserted between the battery and battery contact. I then connected the two wires to an ammeter. Voila!

A hack to easily measure electrical current use of a battery powered device
This is a little hack to measure the current use of a battery powered device. I used this in a recent Lidl LED nightlight teardown. These nightlights came with plastic spacers which kept the battery disconnect until it was ready for use.
I covered both sides with copper foil tape, soldered wires each side and reinserted between the battery and battery contact. I then connected the two wires to an ammeter. Voila!
