How long do hearing aid batteries last? They can last between 70 and 185 hours, but it depends on several factors such as the type of hearing aid, the battery brand, the size of the battery and the amount of time the hearing aid is in use for each day. You can also get rechargeable hearing aids and batteries. Read on to find out more...
This is an important question for users of hearing aids to consider. The lifespan of hearing aid batteries can be crucial when it comes down to purchasing a new device or looking for value for money.
Worrying about how long your hearing aid batteries are going to last is a constant problem for hearing aid users. It is a legitimate question, one that we've discussed before in the post 'Hearing Aid Batteries Questions and Answers', however, we felt that this topic deserves more attention for a number of reasons.
1. The battery's duration may be a consideration when buying a new hearing aid. You may prefer to buy one model instead of the other due to cell lifespan.
2. The cost and daily calculation of operating a hearing aid may be a further consideration. (Essential read: How Much Do Hearing Aid Batteries Cost?)
Much like many battery-related questions, this one is dependant on many variables. Your device will usually dictate the required battery and there are several considerations to take into account:
If we take a look at some of our devices, our HD 91, 151, 230, require size 10 batteries with an estimated 70 hours of battery life. In comparison, our HD 420 requires a size 312 battery which boasts an estimated 185 hours of power. Ultimately, this is down to the technological features each device possesses and battery size. For perspective, the HD 91 is our entry-level hearing aid with one of the smallest batteries going.
This useful video from PowerOne gives tips on the factors influencing battery life:
The answer to this question is not straightforward. A number of factors will influence cell life. So, to know how long hearing aid batteries last, the following things need to be considered:
1. The model - There are many hearing aids on the market, and some are better than others at preserving sources. Even within a hearing aid manufacturers brand, one model may be better than another in terms of battery consumption.
2. Type of use - Naturally, the more you use the device, the quicker the batteries will deplete. Hearing aids belong to a group of high demanding devices and require optimal power consistently. It is only when the device is switched off that power is not used.
3. Brand of batteries and power technology - There are a number of brands for providing specialist hearing aid batteries, from Rayovac to Duracell. Within each brand, there are normally two or more lines of power technology, so this factor will also influence battery life.
4. All zinc-air batteries rely on the air entering the battery to start the reaction that produces power. When you first receive your battery, it will have an adhesive tab on the bottom to prevent air from entering the battery and starting the reaction. As soon as you remove this tab, the reaction and battery life begin. The battery's life will continue to deplete, even if not in use.
Bearing in mind the above factors, we recommend that you familiarise yourself with your device’s low battery warning notification process. After a while, you will become accustomed to the length of time you can expect your batteries to last for your particular hearing aid and its typical usage pattern.
Furthermore, you should consider carrying an additional battery set just to be on the safe side, and as a final tip, make sure you follow our recommendation for the safe storage of these batteries.

Increasingly you can get hearing aids which are rechargeable. You can plug them into a USB cable or a charging cradle overnight to get a full day's use.
