The market for mobile Bluetooth speakers is growing rapidly. New or updated models are constantly appearing in shops. When looking for a battery that is compatible with your speaker, be sure to check the polarity of the plug. The different models in the Charge range differ in this seemingly imperceptible nuance. Before you choose the right link, check the list of supported devices and be sure to check the order of the red and white cables in relation to the black wire going to the plug. An old battery pack will certainly help, which you can model on. Battery replacement – good practices To remove the outer speaker cover, lever it off with a plastic or wooden spatula, being careful not to scratch the case. 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 how the different coloured wires are arranged in order, then connect the new battery in the same way.
