Power One Size 312 Hearing Aid Batteries — 300-Count (50×6) with Extended Tabs, Long-Lasting Zinc-Air

Power One Size 312 hearing aid batteries — a 300-count supply designed for long-lasting, reliable power with easy-to-use extended tabs.

These Power One zinc-air batteries are produced in Germany and engineered for precision, stability and consistent voltage across cycles. Each cell is individually tested and sealed to reduce the risk of premature drying or drainage. The stainless steel casing resists corrosion, while the consumer-focused extended tabs make insertion and removal simpler for routine use.

How long will one Power One Size 312 battery last in daily use?

Runtime depends on your hearing aid model, volume settings and daily hours of wear, but these batteries are built for steady voltage and extended life. Patented cathode materials aim to sustain higher cell voltage for longer, which can delay the next battery change and keep sound quality consistent.

• High-voltage cathode chemistry for prolonged performance
• Individual cell testing to ensure each battery meets specs
• Film seal technology to prevent premature drying

Are these batteries easy to handle for people with limited dexterity?

Yes — Power One supplies these cells with extra-long tabs that give a larger grip area and make inserting or removing batteries easier. The tabs reduce the need to pinch tiny edges, which is helpful for users with reduced hand strength or coordination.

• Extended tabs for improved grip and manipulation
• Stainless steel housing for secure, rigid handling
• Clear size marking to avoid selecting the wrong cell

What quality and safety checks are performed on these batteries?

Manufactured at a high-capacity facility in Ellwangen, Germany, each cell undergoes electrical and mechanical testing against strict specifications. In addition, a specialized film seal and corrosion-resistant housing support stability and reduce the chance of early failure.

• Each cell tested for electrical and mechanical characteristics
• Production adheres to stringent German safety and quality standards
• Durable film seal to protect against drying out during storage

How should I store these Size 312 batteries for best performance?

Keep batteries in a cool, dry place and avoid extreme temperatures or humidity to preserve the film seal and prevent self-discharge. Store them in their original packaging until use and remove the tab just before inserting the battery in your hearing aid to maximize shelf life.

• Store in original blister packs until use
• Avoid direct sunlight, heat sources and damp areas
• Remove tab immediately prior to insertion to activate cell

This 300-count pack (50 packs of 6) is ideal for daily wearers, caretakers, clinics or anyone who prefers to buy in bulk and minimize reordering. If you value consistent voltage, tested manufacturing, and easier handling, these Power One Size 312 batteries provide a dependable, economical supply for a wide range of hearing instruments.
