〔 Coin Type Primary Lithium Batteries 〕
■ When the batteries are used with a contact system
● Use nickel-plated phosphor bronze or stainless steel for
terminal materials to make contact with the batteries.
● For stable contact conditions, several N of contact pressure
are recommended for the contact.
