I) Equipped with flat terminals plated with Rui or Mg plating,
A common method is to form sliding spring terminals made of the same material on the equipment side, and then slide the battery into the battery storage space of the equipment and bring the terminals into contact at the same time. In this case, the flat terminal on the battery side is engaged with the battery lid, which is a container made of synthetic resin. For this reason, when a large current flows, heat generation due to contact resistance becomes significant, exceeding the melting temperature of the battery lid, causing damage to the battery such as puncturing the terminal mating portion, and causing a loss of functionality.
