After removing these screws, you will see. That the rbc5 battery pack is connected to the unit via two wires at both ends of the batteries. The first wire that should always be disconnected first is the red wire. That goes to the positive terminal, then the negative wire to avoid any possibility of sparking. Once these cables are removed, the rbc5 battery pack should simply slide out of the unit.
Once you have your rbc5 replacement battery ready to use. Slide the battery into the unit far enough to connect the positive terminal. Then slide the battery in far enough to connect the negative terminal. Close the metal door with the two screws you removed earlier (hopefully you didn’t lose them).
