Portable appliances — whether it is a modern alarm clock, a radio-transistor, audio player or the flash — not the same design as the compartments for batteries and contact sockets; and “batareiki” may be slightly different from different manufacturers. For example, metal liners, chemical elements of power “373” (“Orion M”) both end over-rolled, whereby negative electrode (see Fig.) is somewhat recessed inside and when you install, for example, in the desktop electro-mechanical clock VESNA not provide contact with the circuit device.
Rescue stationery metal clip. It is only necessary to slightly bend towards the negative electrode element of its middle part: get “contact spring”. You can also use the appropriate size washers, discs, coins, etc.
