Before you buy
What to consider
When selecting a 312 hearing aid battery, start with the expected runtime. If you prefer changing batteries every few days, a budget pack like Energizer may be sufficient. For users who want the longest possible usage between changes, Duracell or Rayovac provide a steadier voltage curve that can extend battery life by up to a day.
What to consider
Leak protection is another critical factor. Batteries that use sealed metal tabs and moisture‑absorbing strips-such as Panasonic and Duracell-reduce the risk of corrosion inside the hearing aid, which can be costly to repair. Finally, consider packaging size and price per unit; larger packs lower the cost per battery but require more storage space, while compact packs like Varta are ideal for on‑the‑go situations. Balancing these criteria will help you keep your hearing aid reliable and your ears happy.
Quick answers
A standard 312 battery lasts between 3 and 5 days depending on the hearing aid’s power consumption and your daily usage patterns.
Rechargeable 312 batteries are limited, but the Phonak Rechargeable 312 offers about 12 hours of use per charge and works with most Phonak models.
