    Disposable Batteries

    These batteries hold more power than rechargeable batteries but must be replaced more frequently. When choosing a battery, use the capacity, measured in milliampere-hours, to compare among similar sizes. The higher the mA-hr. rating, the longer the battery should last.

    Batteries

    Battery contacts provide a reliable electrical connection between batteries and circuit boards in custom battery holders and electronic devices. Nickel-plated steel construction resists corrosion.
    Button contacts sit against the positive terminal of the battery, providing a fixed connection point. Spring contacts press against the negative terminal, using spring tension to hold the battery securely in place and maintain consistent electrical contact despite vibration or movement. Pair a button contact with a spring contact to create a complete battery holder connection.

    Mount batteries directly to circuit boards with these contacts, which eliminate the need for separate battery holders and reduce board space. Nickel-plated steel or tin-nickel-plated steel construction provides reliable electrical conductivity and corrosion resistance for long-term contact integrity.
