Every hearing aid requires batteries, if you are having trouble listening even though you have your device on you need to check your batteries.But beware it could even be some other technical problem, or if you use the computerised device programmed specifically to suit your needs than maybe its time to visit the clinic to re-access your case.
Before you change the batteries of your device be sure to know certain technicalities about your machine like the hearing aid batteries size and type of batteries(alkaline or non-alkaline).These are different for different devices thus if you pick up a wrong pair of batteries they are of no use.
There are a few more things one must take care about when changing batteries be sure to check the positive and negative terminals of the batteries and then align the batteries properly. If you are in a cold zone the batteries could go cold and not function properly, in such instances wait till the batteries warm up and see if they function well before you change them. Never mix old and new batteries this draws more power from the new one shortening its life .Also never mix brands or types like alkaline and non-alkaline this will reduce the life of a battery. If for some reason you do not intent to use the hearing device remove the hearing aid batteries never leave them in the device as there are chances of leakage. Please do not leave the device switched on after use as this will drain the batteries. If you buy some extra batteries store them in a cool place as heat will accelerate the chemical reaction in them and reduce their life span. Never remove batteries from their packing before use.
