Battery holder
Many types of battery holders are commercially available for standardized battery sizes. A battery holder generally comprises a housing for accommodating a battery (or a plurality of batteries connected in serial and/or parallel), and a negative (-) side contact and a positive (+) side contact arranged in the housing. The battery holder is equipped with positive and negative electrodes that electrically and respectively engage with positive and negative terminals of the battery for routing the electricity from the battery to a power consuming device to which the electrodes of the holder are connected. The negative and positive side contacts are arranged so that they can be brought into contact with a negative (-) and positive (+) electrodes of a battery to extract from these contacts a battery voltage which is then supplied to a load circuit. A battery holder receives and retains a dry battery, such as "A", "AA", "1/2AA", and "AAA" size batteries, comprising a cylindrical body having a first flat end surface, serving as a negative terminal, and a second end surface from which a cylinder concentrically projects, serving as a positive terminal. A battery holder for a mobile phone generally comprises a hollow locating rod raised from the shell thereof, a cylindrical spring member mounted in the hollow locating rod, and lock means supported on the cylindrical spring member and adapted for securing the battery holder to the mobile phone. Battery holders are often lightweight brackets for holding a plurality of batteries in series or in parallel to provide a fixed voltage. In most commercial battery holders, batteries are installed from the sides and retained by resilient electrometric members on the side of the holder. Battery holders for real time clocks in desk top computers is installed on the main or other circuit boards of the computer by terminal tails which are inserted into the circuit boards and soldered to the appropriate electrical circuit of the boards.
