The Rayovac 10AC hearing aid battery (size 10, colour code yellow) in the practical 6-pack blister is the premium choice for users of extremely small in-the-ear hearing aids (ITE/CIC). Rayovac is one of the world’s leading and most innovative manufacturers in hearing aid acoustics and stands for unrivalled reliability and consistent performance.Thanks to advanced zinc-air technology (Zinc-Air) and the "Active Core Plus" architecture, this tiny battery delivers extremely high energy density. It reliably and distortion-free powers modern, digital hearing aids with wireless or Bluetooth functions, allowing you to rely on clear hearing and understanding in every situation.Highlights at a GlanceColour code yellow (size 10): Globally standardised colour coding, making re-purchasing extremely easy – if your device requires “yellow”, this is the right battery.Maximum runtime: The optimised cell construction offers a constant voltage level and well above-average service times, even with demanding hearing aids.Zinc-Air technology: The battery activates itself automatically through contact with oxygen as soon as the protective sticker is removed.Long shelf-life: Unopened and with an intact seal, Rayovac batteries can be stored for up to 4 years without any significant loss of performance.Convenient blister: The practical rotary dial packaging (Dial-Pack) enables safe, single removal of the batteries while the rest remain protected.Corrosion-free: The high-quality stainless steel case prevents leakage and protects the delicate electronics of your hearing aid.Areas of ApplicationSize 10 (yellow) is the smallest standard hearing aid battery and specially designed for:In-the-ear hearing aids (ITE): Especially for the tiny CIC devices (Completely in Canal) and IIC devices (Invisible in Canal) which sit deep in the ear canal.Mini behind-the-ear devices (BTE): Very compact and discreet BTE models with thin sound tube (RIC/RITE).Digital streaming devices: Provides the required power reserves for devices that connect to smartphones or televisions.Assembly & Safety InstructionsActivation time (very important!): Remove the yellow sticker and ensure the battery “breathes” in air for 1 to 2 minutes before inserting it into the hearing aid. The battery requires this oxygen to build up its full voltage of 1.45 V.Fresh seal: Only remove the sticker immediately before use. Once pulled off, the chemical discharge process begins, even if you put the sticker back on.Storage: Store the blister packs at normal room temperature (approx. 10°C to 25°C) in a dry location. The fridge is not suitable, as condensation can damage the freshness seal.Disposal: Zinc-air batteries must not be disposed of in household waste. Place empty cells (often recognisable by missing sticker) in battery recycling boxes at your hearing care professional or supermarket. Features Model / TypeRayovac Extra Type 10 (10AC) Colour code**Yellow** (standard for size 10) Technology**Zinc-Air** (Zinc-Air) Nominal voltage**1.45 V** Nominal capacity**100 mAh** Dimensions (Ø x H)**5.8 mm x 3.6 mm** Packaging unit**6-pack blister** Mercury-freeYes (Mercury Free) Comparison typesPR70, DA10, V10A, A10, 10A, L10ZA FAQs about the Rayovac 10AC blisterHow long does a size 10 battery last in my hearing aid?This depends greatly on individual usage. Because size 10 is extremely small, it holds less energy than larger models. On average, it lasts about 3 to 7 days. The exact runtime varies depending on hours worn per day, the set volume, surrounding noise level, and use of Bluetooth streaming.Does this battery fit Phonak, Signia or Widex devices?Yes, without restriction. Hearing aid batteries are completely standardised. Regardless of your hearing aid manufacturer (Audio Service, Phonak, Signia/Siemens, Starkey, Widex etc.) – if your old packaging says “10” or the tab is Yellow, this Rayovac battery is a perfect fit.My hearing aid warns shortly after inserting that the battery is empty. Is it faulty?Most often this is due to too short an activation time. If you remove the yellow sticker and immediately insert the battery and close the battery compartment, not enough oxygen could flow into the cell. The device will then measure too low a voltage. Take the battery out again, wait 2 minutes and try again.
