A quick search on google or Bing shows me that there are very many companies advertising their services to service hearing aids. It seems that the range in cost for a hearing aid repair is between $30 to $100 and these generally come with a 6 to 12 month warranty. The providers also offer full hearing aid rebuild but the prices are generally higher, more in the range of $175. On the surface I have to suggest that this is sounds like a great deal. To fix a $3000 product for as low as $175 is a fantastic deal.
Of course, the price of the batteries is going to vary depending on where you purchase them. Considering the average price for hearing aid batteries in a retail store, here is a breakdown of what you can expect to spend on batteries for two hearing aids per size:Size 10: an average of $150/year. Size 312: an average of $80/year. Size 13: an average of $50/year. Size 675: an average of $30/year.If battery size and cost is important to you then you want to be sure to discuss this with your Audiologist when purchasing hearing aids. Be aware that the smaller the hearing aid is, the smaller and more costly the batteries will be.he reason for that is the digital processing that is taking place in a hearing aid is much more complex than that of a watch. Assuming the hearing aids are being worn 14-16 hours/day, the lifespan of a hearing aid battery will depend on a few factors: 1  The size of the battery. 2  The processing of the hearing aid.
