The question of precisely how long hearing aid batteries should be expected to last is not as simple to answer as it seems, because battery life hinges on numerous factors. Battery life will depend on the model of your hearing aid, and can vary widely across unique models created by the same manufacturer. The way you use your hearing aid will also affect battery life; the more hours a day it is turned on, the more rapidly you will use up batteries.

There are even different battery lives in the exact same size of hearing aid battery depending on the manufacturer, and depending on whether you are purchasing that manufacturer’s “premium” line or their “normal” line of batteries. Battery type is another key factor in longevity. For example, zinc-air batteries will start to lose power the instant you remove the adhesive tab on the bottom and will continue to lose power even if the hearing aid is turned off while other types will only drain when they’re in a hearing aid that is powered on.

Because the expense of hearing aid batteries adds up, if you are looking for a new hearing aid, you should do some research to find out which types and models of hearing aids have the best battery life, because that may influence your choice. The same research suggestion is true if you have an existing hearing aid and are trying to find the batteries with the longest life for it; you can learn a great deal from consumer ratings and comparative reports.

To make things somewhat easier for you, hearing aid batteries are produced in 4 common sizes, each of which is marked with a distinct color code, which is always the same no matter who the manufacturer is. The following list of battery life is estimated, of course, but it should give you a general idea of how long batteries of each size should last:

  • Size 10 – Yellow tag – 80 hours
  • Size 13 – Orange tag – 240 hours
  • Size 312 – Brown tag – 175 hours
  • Size 675 – Blue tag – 300 hours

For the longest battery life, remember to turn your hearing aid off when you’re not using it. Store your unused hearing aid batteries at room temperature, indoors, and in their original, unopened packaging to ensure their longest possible life.
