From phones to cameras to music players, how we power our electronics has progressed. A powerful, rechargeable hearing aid battery is finally realizing the hopes of hearing aid makers to replace the antiquated disposable power sources of the past.
Size 312 batteries are the most prevalent of the disposable batteries that have typically been used to power hearing aids. The most popular form of this battery, now, is “zinc-ion”.
Disposable Hearing Aids Have a Disadvantage
As the name would imply, a zinc-air battery is affected by the presence of air. The user has to pull a little tab off the back of a 312 zinc-air battery to activate it.
They will begin losing power as soon as they are completely oxygenated. That means power is beginning to drain even if the user isn’t ready.
Most users consider the duration of life to be the greatest disadvantage of disposable batteries. With 312 batteries, the user might be replacing the batteries in their hearing aids around 120 times every year because they die in 3 to 12 days according to some reports.
Because of this, besides needing to purchase 120 batteries, the user will need to change and correctly dispose of batteries at least twice a week. That’s probably over $100 in batteries from a cost outlook alone.
Rechargeable battery Improvements
Thankfully, for hearing aid users looking for another approach, there have been significant improvements to rechargeable hearing aids that now make them a practical choice.
The vast majority of people would wear rechargeable hearing aids if given a choice according to some research. Over the years, these models were impractical because they didn’t hold a charge long enough. However, recent innovations now facilitate an entire day of use per charge.
Rechargeable batteries won’t save users substantial amounts of money, but they will make quality of life better.
In addition to supplying 24 hours of use time, these new models result in less frustration for the user, since there’s no more changing and properly disposing of batteries. They simply need to place the battery on the charger.
A disposable battery nearing the end of its life simply can’t operate at full capacity. There’s also no exact way to know how near to being inoperable the battery really is. As a result, users risk putting themselves in a situation where their battery might die at a critical time. A dead battery will not only result in a safety hazard, it could cause the user to miss out on key life moments.
Types of Rechargeable Hearing Aid Batteries
There are unique benefits to each of the different materials that rechargeable batteries are constructed from. The ability to maintain a charge for 24 hours is one reason why integrated lithium-ion batteries are one practical option that manufacturers provide. And cellphones are powered by this same type of battery which may be surprising.
Silver-zinc technology is another material used for today’s rechargeable hearing aids. Initially, these revolutionary batteries were developed for Nasa’s moon missions. You can even use this technology to modify and retrofit the existing hearing aids you’re comfortable with by converting the device to rechargeable power. Just like lithium-ion, silver-zinc can also provide enough power to last you for a full day.
Some models even let you recharge the battery while it’s still in the hearing aid. For these, users will place the entire hearing aid into a charging station when they sleep or at another time when the hearing aid isn’t in use.
Whichever solution you choose, rechargeable batteries will be considerably better than disposable batteries. You just need to do some research to determine which option is ideal for your needs.
