Fresh Date Code Guaranteed

• Chemical System: Zinc-Air
• Nominal Voltage: 1.45 Volts
• Typical Capacity: ~300 mAh
• Mercury Content: 0% Mercury (100% Mercury-Free formulation)
• Typical Weight: 0.83 grams
• Air-Access Optimization: Utilizes a precision housing construction that controls exactly how much oxygen enters the cell. This stabilizes power delivery during high-drain tasks like wireless streaming or digital noise filtering.
• Flat Voltage Profile: Provides a constant 1.45V discharge throughout the battery's active lifecycle. This eliminates early distortion, volume drops, or intermittent audio cutouts.
• Elongated Adhesive Tabs: Designed with oversized, easily recognizable orange tabs. This aids user handling, peeling, and alignment for those with limited hand dexterity.
• Activation Requirement: Because it relies on ambient oxygen to run, you must wait 60 seconds after removing the orange tab before closing the hearing aid battery door. This lets the core chemistry reach full saturation.
