Oral hygiene is an important daily ritual that every individual should follow. Using an electronic toothbrush is a great way to ensure that you will be able to clean every tooth in a matter of minutes. However, the Oral B Cross Action will eventually need a new battery after using it on a regular basis. Changing a battery on your electric toothbrush is very easy to do and is far more affordable than purchasing a new toothbrush.
Rub your toothbrush's handle with a dry towel. Next, carefully unscrew the bottom of the toothbrush and remove the battery. Throw the dead battery away.
Remove the new AA battery from its packaging and place the battery into your Cross Action toothbrush.
Put the handle back onto your toothbrush by carefully screwing it back on tightly. Turn on your toothbrush to make sure the new battery works properly. If your toothbrush still does not work, unscrew the handle once again and make sure that the battery is facing the right direction.
