What kind of battery does weighing scale use?

Weighing scale usually uses the No.5 battery because it has some characteristics suitable for weighing scale. The 5th battery is relatively small, which is easy to carry and replace. This is an important consideration for people who need to move or travel frequently. Weighing scale usually uses three No.5 batteries, because this combination can provide enough power to ensure the normal work of weighing scale.
