312 Batteries

Size 312 hearing aid batteries

Size 312 batteries are among the most commonly used power sources for modern hearing aids. The compact design combined with reliable capacity makes this size particularly suitable for many RIC and behind-the-ear models. The standardized brown color code allows 312 batteries to be quickly recognized and safely distinguished from other sizes.

These batteries are based on proven zinc-air technology. After removing the protective tab, the battery reacts with oxygen and delivers a constant voltage of 1.45 volts. This stable energy supply is essential for consistent amplification, clear speech transmission and reliable operation of hearing aid components.

312 batteries from well-known brands

We offer 312 batteries from established manufacturers known for quality, long runtime and stable performance. Depending on the brand, energy density, packaging systems and shelf life may vary.

Why choose size 312 batteries

Size 312 offers a balanced combination of performance and runtime. It is more powerful than size 10 but more compact than sizes 13 or 675, making it ideal for hearing aids with moderate energy demand.

Many users choose this battery size because it provides several days of stable performance. Depending on the hearing aid model, daily wearing time and the use of streaming features, typical runtime ranges from approximately five to seven days.

Advantages of 312 batteries

312 batteries provide stable voltage output throughout their entire usage period. This reduces performance fluctuations and helps maintain consistent hearing quality.

The practical packaging makes it easy to remove individual batteries while protecting unused cells from environmental influences.

Modern versions are mercury-free and comply with current environmental standards without compromising performance.

Replacing 312 batteries

Carefully open the battery compartment and remove the used battery. Then remove the protective tab from the new 312 battery and wait a few seconds so the zinc-air reaction can fully activate. Insert the battery with the positive side facing up and close the compartment securely.

Store batteries in a dry environment at room temperature and avoid contact with metal objects such as coins or keys to prevent short circuits.
