AG0 / LR521
A small battery, but massive importance to performance. The VIDEX AG0 / LR521 alkaline cell is specially designed for ultra-fine watches, guaranteeing continuous power in low-drain devices.
Why VIDEX button batteries are a smart purchase:
- Pazīstama arī kā (analogi): LR521, 379, SR521SW.
- High price-to-quality (TCO) ratio compared to expensive premium brands.
- Excellent resistance to oxidation, protecting device contacts from rust.
- Precise dimensions ensuring a perfect and snug fit with no wobble.
Never run out of power at the worst possible moment. Buy affordably at open tools!
Q: What are the extreme physical dimensions of the AG0 / LR521 battery and its main function?
Q: Why is micro-format power necessary in medical endoscopic (pill) cameras?
Q: How does VIDEX ensure airtightness in such a microscopic battery as the LR521 (AG0)?
Q: How does the micro (10 mAh) capacity affect the replacement frequency of the AG0 battery in luxury watches?
Q: What should be done if a pet (or child) accidentally swallows a miniature battery like the AG0?
A: The AG0 (known as 379A) is the smallest 1.5V coin cell format in the world – 5.8 mm in diameter and only 2.15 mm thick, providing an extremely small capacity (around 10 mAh). This nano-format is designed for special medical micro-implants and ultra-mini quartz mechanisms, where even a fraction of a millimeter in width is critical.
Q: Why is micro-format power necessary in medical endoscopic (pill) cameras?
A: The capsule swallowed by the patient must be as small as possible (under 10 mm in thickness) to safely pass through the digestive tract. To power the micro-camera and wireless transmitter during its short 8–10 hour duty cycle, multiple 5.8 mm (AG0 format) batteries connected in series are used.
Q: How does VIDEX ensure airtightness in such a microscopic battery as the LR521 (AG0)?
A: Despite the tiny 5.8 mm diameter, the AG0 model integrates the same two-stage nylon seal as in the large formats. This extremely precise metalworking and polymer sealing protects expensive watch and sensor micro-mechanisms from corrosive alkali (electrolyte) leaks even at the end of complete discharge.
Q: How does the micro (10 mAh) capacity affect the replacement frequency of the AG0 battery in luxury watches?
A: Even with the strictest Low-Drain quartz motor optimization, the physical energy limit (10 mAh) in luxury watches requires regular service. The AG0 (or silver oxide SR521SW) battery typically provides up to one year of autonomy, after which preventive replacement is necessary before the voltage drops entirely below 1.2V.
Q: What should be done if a pet (or child) accidentally swallows a miniature battery like the AG0?
A: Despite its 5.8 mm size, it is still an electrochemically active (1.5V) device which, upon contact with stomach acid, causes severe internal chemical burns. This is a medical emergency – you must go to the nearest hospital immediately for an X-ray, without waiting for any poisoning symptoms to appear.
