Changing a battery – good practices To remove the outer speaker cover, lever it off with a plastic or wooden spatula, being careful not to scratch the casing. When replacing the battery you will also need a screwdriver. Use this to unscrew the unit. Many speaker models require you to remove a large number of screws to reach the battery. If you have trouble removing a part, do not use force! First make sure that all fixings have been properly unscrewed or removed. If you feel resistance when removing the old battery from the speaker, proceed with caution! Do not jerk the cell or use excessive force. Remember that a swollen or damaged battery can be a real danger to you or the environment. If you have a speaker model where you have easy access to the back wall of the battery compartment after disassembly, it is a good idea to use double-sided adhesive tape. Stick one side of the tape to the wall of the speaker, attach the other side to the new battery. Note the polarity of the battery. Before you remove the old cell, look at how it was connected. Memory can be unreliable, so take a picture just in case! Check the order of the different coloured wires, then connect the new battery in the same way.
