AG2 / LR726
Precision and reliability are key when working with fine electronics. That's why the AG2 / LR726 format Alkaline battery from VIDEX is created for delicate wristwatches, providing industrial-standard reliability in every hour of use.
Why masters and users trust VIDEX 1.5V cells:
- Pazīstama arī kā (analogi): LR726, 396, SR726W.
- Constant current level prevents reading errors (e.g., in measuring tools).
- Safe shelf life, allowing you to buy them as backups.
- Economical choice, paying for full power rather than unnecessary marketing.

Q: What are the IEC parameters of the AG2 / LR726 battery and its specific application?
Q: Why are LR726 alkaline elements used in ultra-thin smart rings?
Q: How does an AG2 (LR726) battery behave in precision chronometers compared to a silver oxide SR726SW?
Q: Can thinner AG11 (LR721) batteries be inserted into a socket designed for AG2?
Q: How to replace an AG2 battery in a delicate women's wristwatch without damaging the contact mechanism?
A: The AG2 battery has a diameter of 7.9 mm and a thickness of 2.6 mm, providing around 25 mAh capacity at 1.5V voltage. This hybrid format is designed for small-sized women's quartz watches and thin smart rings, where a narrow diameter is needed but there is no room for the 3.6 mm thickness of an AG3.
Q: Why are LR726 alkaline elements used in ultra-thin smart rings?
A: The microprocessors and Bluetooth Low Energy (BLE) modules of smart rings continuously send micro-pulses. The thin (2.6 mm) but relatively capacious (25 mAh) architecture of the VIDEX LR726 battery allows combining wearing ergonomics with sufficient autonomy for sensor operation.
Q: How does an AG2 (LR726) battery behave in precision chronometers compared to a silver oxide SR726SW?
A: The SR726SW silver oxide element maintains an ironclad 1.55V voltage down to the last drop of energy, which is critical for luxury class chronometer mechanics. The voltage of the alkaline LR726 drops slowly, which is economically justified for simple everyday watches and children's musical toys.
Q: Can thinner AG11 (LR721) batteries be inserted into a socket designed for AG2?
A: This can be physically done, as both have a 7.9 mm diameter, but the AG11 is 0.5 mm thinner (2.1 mm). As a result, poor contact with the device's spring will occur, causing electrical circuit breaks during movement or impact, making the power supply unstable.
Q: How to replace an AG2 battery in a delicate women's wristwatch without damaging the contact mechanism?
A: Battery replacement must be done with polymer or ceramic tweezers, ensuring the battery is positioned so that the smooth metal cap (positive) faces the back cover. Since the 7.9 mm size is very small, even the slightest grease print or moisture from fingers will create galvanic resistance (micro-ohmic resistance).
