The battery of hearing aids have very much evolved in the last three decades, with the introduction of zinc based batteries the overall longevity with performance quality has been upgraded manifold. Also there have been several upgrades in chemical composition making the batteries work to their best performance before being totally drained out. This has positively impacted upon the performance of the hearing aids, earlier when this conceptual reality would make the user suffer with diminishing performance. Nowadays, one can expect prolonged hearing quality to some extend before the batteries are fading out completely.

Though nowadays most of the hearing aids are well equipped with ‘low battery’ indicators which is a good thing, but one should never use hearing aids when this ‘low battery’ indication is on. Either you must replace the old batteries with new or if in case they are silver zinc or lithium-ion rechargeable ones, you must plug them for charging immediately. As a layman or the user of the hearing aids, one must be aware of certain factual technical information about batteries, at some point when the batteries start to fade out, though it is very abrupt but there is a small time interval in between varying from few minutes to 1.5 hrs (depending upon type/model) during this time the voltage down surges affecting the performance of the equipment. Since last more than a decade globally all major brands are transforming this battery drain out time-slot into an alert feature where hearing aids are designed in a way that whenever they detect voltage thinning they start emitting alerts in the form of specific sound tone, so that the user knows that it is time for a battery change or recharging as applicable.

This phase (low battery indication) varies from few minutes to an hour, but one must understand this is not universal feature across all manufacturer or models of hearing aids. There are still so many types of hearing aids available in the market which does not possess such ‘low battery’ indicator, so it strongly advised that one should change the batteries on regular interval according to the battery life or as suggested with the specific set of hearing aids. Even if you have a battery indicator model, then also it is suggested to change the battery as soon as possible as it is not necessary that hearing aids will work at a best possible level once the low battery indicator is on.

Also as a best practice, the batteries must be kept in a dry place without removing back stickers or seal. Keeping them in refrigerators or with ice never increases the battery life. In fact, this practice can harm the batteries and its sticker seal, which can spoil the batteries, even before you have actually started using it. While changing the batteries it is always better to leave the battery slot of your hearing aids open for few hours in order to reduce the moisture and the dull batteries should be detached immediately. A completely dead battery may bloat and become tricky to get rid of.
