The Rayovac 312AC hearing aid battery (size 312, colour code brown) in a practical 6-pack blister is the world’s most widely used power source for modern, discreet hearing aids. As one of the leading innovators in hearing acoustics, Rayovac guarantees maximum reliability and outstanding sound quality in daily use with this battery.Equipped with tried and tested zinc-air technology and the advanced "Active Core Plus" architecture, size 312 offers the perfect balance between a compact form factor and high performance. It is the ideal choice for popular RIC devices (Receiver-in-Canal) and supplies even demanding digital hearing aids with Bluetooth streaming with completely stable, distortion-free power.Highlights at a glanceColour code brown (size 312): Thanks to globally standardised colour coding, repurchasing is absolutely straightforward – if your old blister or battery tab says "brown" or "312", this is the exact matching cell.Optimum balance: Offers the perfect compromise between tiny size for discreet hearing aids and sufficient power reserves to last the whole day.Zinc-air technology: The battery only becomes chemically active when the brown freshness seal is removed and air oxygen flows into the cell.Long shelf life: With the seal intact and the packaging unopened, you can store these premium Rayovac batteries for up to 4 years without any significant loss of capacity.Practical blister design: The tried-and-tested dial-pack packaging allows secure, single removal of the batteries while the rest remain optimally protected.Leak-proof & Safe: The sturdy, rustproof stainless steel housing effectively prevents leakage and protects the sensitive high-tech electronics of your hearing aid.Areas of applicationSize 312 (brown) is the undisputed standard for discreet and modern hearing aids:RIC hearing aids (Receiver-in-Canal): The absolute standard battery for the popular, extremely small behind-the-ear devices, where the speaker sits directly in the ear canal.Mini behind-the-ear devices (BTE): For very compact BTE models that combine discreet looks with good performance.In-the-ear devices (ITE / ITC): Suitable for in-the-canal models, which are slightly bigger than the tiny CIC devices and provide more space to accommodate this long-lasting battery.Assembly & safety instructionsActivation time (very important!): Peel off the brown sticker and make sure to leave the battery to rest in the air for 1 to 2 minutes before inserting it into the hearing aid. It is essential that oxygen from the ambient air is absorbed, so the battery can reach its full operating voltage of 1.45 V.Keep freshness seal intact: Remove the tab only immediately before use. Once the seal is removed, self-discharge begins, even if the sticker is put back on straight away.Optimum storage: Store your battery stock at normal room temperature (approx. 10°C to 25°C) in a dry place. Storage in the fridge is harmful as condensation may form beneath the sticker and ruin the battery.Environmentally sound disposal: Empty zinc-air batteries should on no account be thrown in general household waste. Please use the special battery collection bins at your hearing care professional, supermarket or recycling centre. Features Model / TypeRayovac Extra Type 312 (312AC) Colour code**Brown** (standard for size 312) Technology**Zinc-Air** (Zinc-Air) Nominal voltage**1.45 V** Nominal capacity**180 mAh** Dimensions (Ø x H)**7.9 mm x 3.6 mm** Pack unit**6-pack blister** Mercury freeYes (Mercury Free) Comparison typesPR41, DA312, V312A, A312, 312A, L312ZA  FAQs about the Rayovac 312AC blisterHow long does a size 312 battery last in my hearing aid?This depends greatly on individual use. The capacity of size 312 is exactly in between the small 10 and large 13 battery. On average, it lasts about 5 to 10 days. If features such as Bluetooth streaming (for phone calls or TV) are used frequently, power consumption increases significantly and run-time decreases accordingly.Does this battery fit Phonak, Signia or Widex devices?Yes, without restriction. Hearing aid battery sizes are strictly standardised internationally. No matter which manufacturer your hearing system is from (Audio Service, Phonak, Signia/Siemens, Starkey, Oticon, Resound etc.) – if your device needs a 312 battery or its battery compartment carries a brown mark, this Rayovac battery will fit 100%.Why does my hearing aid report “battery empty” shortly after fitting?Most of the time, the activation time is too short. If you remove the brown sticker and insert the battery directly and close the compartment, not enough oxygen may have entered the cell. Your hearing aid measures undervoltage and triggers a warning. Simply remove the battery, wait 2 minutes in fresh air and try again.
