Duracell Plus Alkaline Battery MN1604 9V (single blister)

The Rayovac 13AC hearing aid battery (size 13, colour code orange) in a practical blister pack of 6 is the proven and long-lasting power source for a wide range of modern hearing systems. Rayovac As one of the absolute market leaders in hearing aid acoustics, Rayovac stands for uncompromising quality, constant innovation and maximum reliability in everyday use.Equipped with advanced zinc-air technology (Zinc-Air) and the powerful "Active Core Plus" architecture, size 13 delivers a particularly high and stable energy yield. It is the ideal choice for classic behind-the-ear (BTE) devices and easily handles the high power requirements of digital hearing aids that are regularly used for wireless or Bluetooth streaming.Highlights at a glanceColour code orange (size 13): The globally standardised colour coding makes replacement absolutely safe - if your old blister or battery compartment says "Orange" or "13", this is the perfect cell.High power reserves: The size 13 offers significantly more capacity than the small 10 batteries and is ideal for demanding hearing situations and continuous streaming.Zinc-air technology: The battery only becomes active when the orange freshness seal is removed and atmospheric oxygen enters the housing.Long shelf life: Unopened and with the seal intact, you can easily store these Rayovac batteries for up to 4 years without any loss of performance.Practical blister design: The robust rotary disc blister (dial pack) makes it easy to remove individual batteries while the remaining cells remain safely packed.Leak-proof: A high-quality, rustproof stainless steel housing reliably protects the sensitive and expensive electronics of your hearing aid from corrosion.Areas of applicationSize 13 (orange) is the versatile standard for slightly more powerful devices:Behind-the-ear hearing aids (BTE): The most commonly used battery size for classic BTE systems with normal to high amplification requirements.Larger in-the-ear hearing aids (ITE): For models that fill the entire auricle (concha devices) and offer more space for a long-lasting battery.Streaming & networking: Provides the necessary stability for hearing aids that are paired daily with the smartphone, TV adapter or external microphones.Assembly & safety instructionsActivation time (very important!): Peel off the orange sticker and leave the battery in place Rest in the air for 1 to 2 minutesbefore you insert them into the hearing aid. Oxygen from the ambient air is required to build up the full operating voltage of 1.45 V.Keep the freshness seal intact: Do not remove the tab until immediately before inserting. Once the seal has been removed, the battery will slowly discharge itself, even if you press the label back on.Optimum storage: Store your battery supplies at room temperature (ideally 10°C to 25°C) in a dry place. The refrigerator is harmful as condensation can form under the sticker.Environmentally friendly disposal: Empty zinc-air batteries do not belong in normal household waste. Use the battery collection containers at your hearing care professional, supermarket or recycling centre. Features Model / TypeRayovac Extra Type 13 (13AC) Colour code**Orange** (standard for size 13) Technology**Zinc-Air** (Zinc-Air) Nominal voltage**1,45 V** Nominal capacity**310 mAh** Dimensions (Ø x H)**7.9 mm x 5.4 mm** Packaging unit**blister of 6** DurabilityUp to 4 years (shelf life) Comparison typesPR48, DA13, V13A, A13, 13A, L13ZA  FAQs about the Rayovac 13AC blister packHow long will a size 13 battery last in my hearing aid?This depends heavily on individual use. As the size 13 offers almost three times as much capacity as a small size 10 battery, it generally lasts significantly longer. On average, you can expect a service life of 6 to 14 days count on. Frequent Bluetooth streaming (e.g. making phone calls or listening to music via the hearing aid) shortens this time accordingly.Does this battery fit Phonak, Signia or Widex devices?Yes, unrestricted. The sizes of hearing aid batteries are strictly standardised internationally. Regardless of which manufacturer your hearing system comes from (Audio Service, Phonak, Signia/Siemens, Starkey, Oticon etc.) - if your device requires a 13 battery or a orange markings, this Rayovac battery fits 100%.Why does my hearing aid report "battery empty" shortly after insertion?The most common reason is that the activation time is too short. If you peel off the orange sticker, insert the battery immediately and close the compartment, not enough oxygen could get into the cell. The hearing aid then measures an undervoltage and issues a warning. Simply remove the battery again, wait 2 minutes in the fresh air and try again.
