My Energizer® Hearing Aid batteries don’t seem to be working. Now what?

Q: My Energizer® Hearing Aid batteries don't seem to be working. Now what?

A: For best results when using Energizer® Hearing Aid batteries, please allow about 30 seconds after removing the tab for your battery to "air-up" to full power before inserting into your hearing aid. To get the most out of your batteries, open the door on your hearing aid when not in use to stop battery drain and allow air to evaporate any moisture buildup.

Do batteries expire?

Q: Do batteries expire?

A: Yes, all good things must come to an end. To find the Best If Used By (BIUB) date of the batteries in question, please look on the uppermost section of the cells, near the battery type (AA, 9V, etc.). You will see a white box with the Best If Used By year printed within it.You can find smaller cells BIUB on the packaging. The best consumer experience and battery performance occurs with battery usage before the Best If Used By Date. The battery may function beyond that date but with lower performance.

Can you mix different brands of batteries?

Q: Can you mix different brands of batteries?

A: As chemistries and voltage vary across both battery types and brands, we recommend that you do not mix batteries. Mixing of cells can result in battery leakage and sub-optimal device performance. For best results, replace all batteries with the same brand, chemistry, voltage, and size when the device performance becomes unsatisfactory.
