Why are my hearing aid batteries dying so fast?

A Battery Can be Drained by Moisture In addition, you may live in a rainy or humid climate where things get even wetter. The air vent in your hearing aid can get clogged by this extra moisture and it will be less effective. Moisture can also interact with the chemicals of the battery causing it to deplete faster.

Should you remove hearing aid batteries at night?

Leave the battery compartment of your hearing aid open at night so moisture can escape. Doing so will keep the battery from corroding and damaging the hearing aid. Remove dead batteries immediately. A completely discharged battery may swell and become difficult to remove.

How often do hearing aid batteries need to be replaced?

every three to ten daysAnswer: Depending on your hearing aid model and level of usage, your batteries will need to be changed every three to ten days.

How long is a lithium ion battery?

Many are also available with internal protection circuits that can increase their physical length; for example, an 18650 is around 65 mm (2.56 in) long, but may be around 68 mm (2.68 in) long with an internal protection circuit. Some such circuits increase cell diameter instead. The increased dimensions may mean the cell will no longer fit in battery compartments intended for cells without such circuitry.

What does CR mean in lithium?

The IEC prefix “CR” denotes lithium manganese dioxide chemistry. Since LiMnO 2 cells produce 3 volts there are no widely available alternative chemistries for a lithium coin battery. The “BR” prefix indicates a round lithium/carbon monofluoride cell. See lithium battery for discussion of the different performance characteristics. One LiMnO 2 cell can replace two alkaline or silver-oxide cells.

How much air does a hearing aid battery need?

Each cell needs around 1 cc of air per minute at a 10 mA discharge rate. These cells are commonly used in hearing aids. A sealing tab keeps air out of the cell in storage; a few weeks after breaking the seal the electrolyte will dry out and the battery becomes unusable, regardless of use.
