ULTRA LOW COST BATTERY TESTER FOR HEARING AID USERS

 

REQUIREMENT

 

Hearing impaired persons use hearing aids, There are a variety of hearing aids from low cost to very high cost. Hearing aids require a battery to operate. The low cost hearing aid is popularly known as the 'Body level hearing aid', this aid uses a AA size battery.

The hearing aid is an important part for the user's living and the breakdown or a defect of it effects him greatly leading to wastage of time, his daily wages and service charges. An innovation indicating the status of the battery being used is 'ok' or 'no', in just a simple color band was innovated. Through some additional innovations the battery tester was designed to be very cheap enabling every user to posses one. the innovation helped save a lot of time, effort and money to the hearing aid user.
