4. Dry the batteries:
Remove the batteries from the salted water and dry them completely using a dry towel or cloth. Make sure no moisture remains on surfaces.
5. Test the batteries:
Insert the batteries into a device such as a remote control, flashlight, or toy to check if they have regained their functionality.
Useful tips
Avoid damaged batteries: Don’t try to reuse batteries that are leaking or corroded, as they can be dangerous.
Temporary use: This method does not restore the battery to 100%, but it does provide enough charge for temporary uses.
Responsible reuse: Although it is a useful trick, it will eventually be necessary to take the batteries to a suitable recycling center.
