battery corosion

[Guest guest]

This one is a weird one.

We went to the beach today (at a lake so we are not talking about salty ocean

air) and put both of Bobby's hearing aids in a small change compartment in the

car. The battery compartment was open in both of them to turn off the aids.

The car was hot, but not terribly, the windows were open. Anyway, the only

thing in the compartment besides the aids was some change...pennies, and dimes.

A bunch of them. And we shut the compartment so it probably got hot in there.

When I went to take them out tonight and put them in the dryer, I found that one

of the batteries has corroded and there is a rust kind of film around the inside

of the battery case. I threw out that battery, and I will figure out how to get

the door off so I can clean it, the battery didn't have any sign of explosion,

but I figured it was safer just to replace it anyway. I figured it was a faulty

battery.

Then I took out the other one and it had the exact same thing...the battery had

corroded and that acid stuff was all over the inside of the battery housing.

So does anyone know if storing the aids next to pennies or metal (change) could

do that? Because it obviously wasn't a faulty battery two times. Is the

hearing aid OK? (Assuming I do a hearing check on it and it sounds OK.)

Thanks.
