You can purchase a device at most auto parts stores for that purpose that plugs into your cigarette lighter socket or any accessory outlet and supplies 12 volts to the system while you are changing the battery. This will only work if the lighter or accessory outlet is live when the ignition is off. Another way is to connect another car battery with jumper cables to the positive battery cable you are disconnecting and then to any ground source on the engine. With this method you MUST be very careful to not let that positive cable touch anyplace on the vehicle. If you use that method have someone help you.
Get a "Settings Keeper" <NOCO brand from Walmart in the automotive section by the car batteries>. Follow directions...basically, you plug a 9-volt battery into the cigarette lighter and that supplies power to keep the computer, radio, etc. settings while you change the battery. The "little electrical box" on top of the battery is not involved at all in replacing the battery!
