Ask the expert: your hearing aid batteries life

The Hearing aid batteries area unit a very important thought for anyone wanting to buy a brand new combine of hearing aids.Hearing aid makers have long provided info regarding their products’ battery usage within the “data sheets” that cowl the technical specifications of every hearing aid. As an associate example, Resound’s datasheet for the Resound LiNX2 LS61 shows that the hearing aid (which uses a size 312 battery) drains one.3 milli-Amps (mA) from the once battery tested in “test mode” via the ANSI S3.22 customary.

Battery life (111 hours) =Battery capacity(145mAh)/Current Drain(1.3 mA)

  

In theory, it ought to be straightforward to estimate the expected battery lifetime of the hearing aid. provided that a size 312 battery incorporates a capability of a hundred forty-five milli-Amp-hours (mAh), one just divides a hundred forty-five mAh by one.3 mA to reach associate calculable battery lifetime of 111.5 hours.

First, it helps to know the factors that may cut back battery life. These embrace high or low humanness, extreme temperatures, and high altitude. Also, exploitation advanced options, like audio streaming, drains battery power additional quickly. Here area unit some straightforward steps for increasing battery life and performance:

i. Purchase batteries that square measure as contemporary as potential. explore for expiration dates.

ii. Open the battery door once the hearing aids aren't in use; besides minimizing battery drain, this permits wet to flee.

iii. Do not take away the sticky tabs from the batteries till you’re able to use them.

iv. After inserting new batteries, let the hearing aids sit for a minimum of 2 minutes before swinging them in your ears.

v. Store the batteries at temperature don't refrigerate!

vi. Use a hearing aid dehumidifier; this protects each the hearing aids and its batteries.

vii. Periodically clean the battery contacts within the hearing aids, employing a cotton swab.

vA standard hearing aid battery lasts anyplace from three to twenty-two days, looking at the hearing aid sort, battery sort, and capability, and therefore the quantity of hearing aid use. Hearing aid batteries typically lose power terribly suddenly, therefore it's sensible to hold an additional set of batteries with you in any respect times.

vHearing aid makers typically give estimates of battery life (in hours) beside their product. whereas this can be a definitely associated improvement over battery current drain figures, we tend to encourage caution once reading manufacturer provided estimates.

vLast year, we tend to announce a useful introduction to hearing aid batteries. currently, you’ve got your hearing aids and you recognize a way to use them, however, your batteries appear to be sporting out quickly. Keep reading for a bunch of tips and tricks to assist preserve your batteries as long as potential, and keep your hearing strong!
