.1 of a volt ?

    The button batteries for my hearing aid are 1.4 volt and cost a lot. I have tracked down batteries at a fraction of the cost but they are 1.5 volt. I have used them with no problems, just wondering would the slight increase in voltage cause any long term damage ? Thanks

    Doubtful, the circuit inside the hearing aid probably compensates for voltage drop in the 1.4 volt battery anyway as it nears death and falls towards 1.3, 1.2, 1.1 - whatever regulator they use in the circuit to maintain a useable voltage would probably accept 1.5 too.

    No matter what the Q is, Someone somewhere has tha answer ! Thanks for the quick reply. I suppose the circuit has to be able to accept a slight surge as well as a slight drop. Anyway Thanks again. M
