AG11 / LR721
Precision and reliability are key when working with fine electronics. That's why the AG11 / LR721 format Alkaline battery from VIDEX is created for wristwatches and precision mechanics, providing industrial-standard reliability in every hour of use.
Why masters and users trust VIDEX 1.5V cells:
- Pazīstama arī kā (analogi): LR721, 162, 362, SR721SW.
- 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 is the specification of the AG11 / LR721 battery and its primary microelectronics niche?
Q: Why is the AG11 an irreplaceable element in delicate thermometers and temperature silk sensors?
Q: What are the riskiest mistakes when trying to replace the thin AG11 battery in a device?
Q: How does the alkaline AG11 (LR721) behave compared to similar-sized silver oxide (SR721) versions?
Q: Is the AG11 / LR721 safe to operate in high humidity conditions?
A: The AG11 stands out with a highly compact IEC geometry – 7.9 mm in diameter and only 2.1 mm thick, encompassing about 20 mAh capacity. This miniature 1.5V format is critically needed in thin thermal sensors, hearing aids, and special micro-LED indicators, where space is restricted to tenths of a millimeter.
Q: Why is the AG11 an irreplaceable element in delicate thermometers and temperature silk sensors?
A: The thin architecture (2.1 mm) allows engineers to develop ultra-flat and lightweight thermometer housings that do not bother the user. The VIDEX LR721 (AG11) alkaline element guarantees stable and continuous power to the LCD screen when the thermometer is turned on, ensuring correct C°/F° calibration without blurred digits.
Q: What are the riskiest mistakes when trying to replace the thin AG11 battery in a device?
A: Incorrect polarity and mechanical contact damage are the most common problems in microelectronics. When inserting this 2.1 mm thin battery (with fingers or metal tweezers) it is very easy to bridge the short contact zone of the (+) and (-) poles. AG11 elements must always be inserted using plastic tools, or at least handled only by the edges.
Q: How does the alkaline AG11 (LR721) behave compared to similar-sized silver oxide (SR721) versions?
A: The SR721 silver oxide battery offers 30-40% more capacity and an absolutely flat discharge curve for high-end watches. However, in soft children's toys and simple electronic indicators, where power duration is not measured in years, AG11 (LR721) alkaline technology provides financially accessible power with an identical 1.5V voltage.
Q: Is the AG11 / LR721 safe to operate in high humidity conditions?
A: Alkaline batteries have a metal casing with an internal seal, but the element itself is not IP (Ingress Protection) certified for water resistance. High humidity or direct sweat on battery contacts causes galvanic corrosion, therefore airtightness – for example, in pool thermometers – must be provided by the device's own O-ring seal.
