Hearing aid batteries last anywhere between five and 14 days depending on the above factors. You will know it's time to replace your hearing aid batteries when the aids start beeping. One solution to save money and make batteries last longer is to purchase rechargeable batteries.
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.
