There are four commonly used sizes, which we’ll rank from smallest to largest. The smaller batteries are usually used in smaller hearing aids, while larger batteries are generally used in larger, more powerful hearing aids or cochlear implants.
The smallest commonly used are the size 10 batteries which has yellow colour coding on its packaging. These are commonly used in completely in the ear hearing aids and in the smallest of the over the ear slim tube styles.
The second smallest and possibly most commonly used on the market today is the size 312 battery, which has a brown colour coding in its packaging. This is used for a wide variety of small in-the-ear hearing aids through to small over-the-ear and slim tube hearing aids.
The size 13 hearing aid battery has orange colour coding in its packaging and has the same circumference as the size 312 hearing aid battery, but twice the width. This battery is often used when more power is required as such is commonly found in standard size behind-the-ear and larger in-the-ear hearing aids.
The largest size is the big and powerful size 675 batteries, which has packaging which is colour coded blue. It is almost the circumference of a 5c piece and is used in very powerful hearing aids and cochlear implants. As such it is unlikely that you’ll ever use this type of battery.
Batteries vary quite a bit where their usable life is concerned. They all have a shelf life of about 2 years if the sticker is still attached, but once you start using them a variety of factors that influence their life. As a general rule of thumb, the smaller the battery the less its life. The larger the hearing loss, the more drain on the battery and thus the less life you get from it. Modern hearing aid features such as wireless hearing aid technology also drains a fair bit more current from hearing aid batteries than a non-wireless hearing aid would.
For instance a size 10 hearing aid battery would last about 3 or 4 days in most hearing aids if used consistently. They are generally rated at around 80 or 90 hours of use for an average loss. Size 312 batteries generally last about 1 week on average when used 10 to 15 hours a day. Size 13 batteries can last two to three weeks and size 675 batteries can last as little as 3 days in a high current device such as a cochlear implant or up to 4 weeks in a power hearing aid. Your audiologist should be able to advise you if the lifespan you are getting from your batteries are normal or not.
Most batteries available today are Zinc Air Batteries, which are safer but more variable than the old and dangerous Mercury based hearing aid batteries. All Zinc Air batteries have a sticker attached to the flat (positive) side, which once removed reveals a few holes on the back of the battery. Once the sticker is removed, air can flow into the battery and activate the battery by mixing with the zinc inside the battery. Some Zinc Air batteries still contain a very small amount of Mercury. Completely Mercury free batteries are available, but might last slightly less time.
To ensure you get the best life out of the battery you need avoid touching the flat side of the hearing aid battery and allow at least five minutes “breathing time” before putting the battery in the hearing aid for the first time. Also make sure you disconnect the battery from the hearing aid when the hearing aid is not in use.
Many people like the idea of rechargeable hearing aids and as such there are a couple of hearing aid manufacturers such as Siemens who produce hearing aids that use rechargeable hearing aid batteries. There are a few pros and cons you need to be aware of before deciding to buy rechargeable hearing aids, based on the fact that they are rechargeable.
Rechargeable hearing aids are convenient as you generally place the whole hearing aid in a charging unit, which turns the aid off for you before charging. So clip the hearing aid into the recharger and off you go.
Less need to replace batteries as rechargeable batteries need replacing once every 6 months, compared to a few days or weeks for normal batteries.
Rechargeable hearing aids may last only about 10 hours with a brand new battery before needing charge, which is less than the 10 to 15 hours per day, which many people use modern hearing aids for. So you might need to revert to a normal hearing aid battery if you have used your rechargeable hearing aid battery during the day and wish to use your hearing aid for an evening function as well.
Rechargeable hearing aid batteries lose about half their power gradually over 6 months. So when the time comes to replace a rechargeable hearing aid battery, it will only be lasting you about 5 hours per day!
Rechargeable hearing aid batteries cost a LOT more than normal hearing aid batteries. A set of rechargeable hearing aid batteries retail for about $50 a set and up to $380 for the charger. Traditional hearing batteries cost much less and does not need an expensive charger.
