Powerful in a wide range of miniature applications
The Varta V396 is the ideal energy source when high performance is required in the smallest of spaces. It is used in digital wristwatches with additional functions, in medical devices such as digital clinical thermometers, in small pocket calculators, laser pointers and electronic toys. Their ability to cope with high current peaks guarantees that all the features of your devices function perfectly.
Reliable silver oxide technology (high drain)
The "High Drain" technology of the V396 is designed to meet short-term, high current requirements, such as those arising from a signal tone or LED lighting, without a voltage drop. Compared to cheaper alkaline batteries (such as AG2 or LR726), the silver oxide chemistry offers a stable voltage over the entire service life, which is essential for the precise functioning of electronic and medical devices.
Efficiency and safety with a system
Every Varta battery undergoes strict quality controls to ensure consistently high performance and maximum safety. The V396 is optimally protected against leakage thanks to its high-quality design, thus protecting your devices from damage. The secure individual packaging also prevents short circuits and protects the cell from environmental influences until it is used.

FAQs about the Varta V396 / SR726W button cell
What do the designations SR726W, SR59W or 396 stand for?
These are designations for the same battery size. SR726W is the most common international IEC standard. Here "S" stands for silver oxide, "R" for the round shape, "726" for the dimensions (7.9 mm diameter and 2.6 mm height) and "W" for "High Drain". SR59W is an older standard for the same size. The 396 is the specific type number of the manufacturer Varta.
What is the difference to the low drain variant V397 / SR726SW?
The difference lies in the application. The V396 (high drain) is designed for devices with short-term high power requirements (e.g. light, sound). The V397 (low drain) is optimised for devices with low, constant power consumption such as simple analogue clocks and would last longer in these. Conversely, a V397 would quickly fail in a high-drain device.
Can I use this battery as a replacement for an LR726 or AG2?
Yes, the V396 is a high-quality replacement. While LR726 and AG2 are alkaline batteries whose voltage drops, the V396 silver oxide battery delivers a constant voltage. This leads to a more reliable function, especially in electronic measuring devices, and often also to a longer service life.
How should this button cell be disposed of?
Button cells must not be disposed of with household waste. Please take the empty battery to the designated collection points in shops or municipal recycling centres to ensure environmentally friendly recycling.

SR726SW is the most common international IEC standard, whereby "S" stands for silver oxide, "R" for round shape, "726" for the dimensions (7.9 mm x 2.6 mm) and "SW" for "Low Drain". SR59SW is an older standard for the same size. The 397 is the specific type number from Varta.What is the difference to the High Drain version V396 / SR726W?The two batteries are optimised for different purposes. The V397 (Low Drain) is made for devices with low, constant power consumption like simple analogue watches and lasts longest in these. The V396 (High Drain) is designed for devices with a briefly high current requirement (e.g. light, sound) and would not last as long in a simple analogue watch as the V397.Can I use this battery in a watch with lighting or alarm?This is strongly discouraged. The V397 is not designed to supply the high current peaks required for such features. This can cause malfunctions (e.g. a flickering light) and drastically shorten the battery’s lifespan. For such watches, the high-drain variant V396 is the correct choice.How should this button cell be disposed of?Button cells must not be disposed of with household waste. Please take the empty battery to the collection points provided by retailers or municipal recycling centres to ensure proper environmental disposal.

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.

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.
