I have the same hearing aids from the VA. Do you disconnect the batteries when you aren’t wearing them, the power never shuts off unless you do? I started doing this and doubled the battery life.
You can cut down on ‘squealing’ by keeping your ear canals clean.
I use these little flexible plastic things from Walgreens: ‘Klenere’? A tiny scoop on one end, a reamer-type cleaner on the other end. Almost impossible to hurt your eardrum unless you are just careless.
Good point.....Plus if you put them in a small case or not it feeds back on itself draining the power quicker
