- Stable 1.5V voltage output throughout its lifespan.
- "Anti-leak" protection guarantees that acid won't leak and damage your delicate equipment.
- Secure blister packaging to prevent accidental swallowing (crucial for homes with kids).
Don't overpay for watchmaker services - replace it yourself. Buy affordably at open tools!
Q: What are the exact physical dimensions of the VIDEX AG4 / LR626 battery and why is it the world's most ubiquitous watch cell?
Q: Why do analog quartz wristwatches lose time or freeze unexpectedly when powered by cheap unbranded AG4 cells?
Q: How do LR626, AG4, 377, SR626SW, and SR626 designations differ, and does VIDEX AG4 serve as a direct replacement?
Q: How does the 5-year guaranteed Shelf Life of VIDEX AG4 batteries make it the ideal choice for watch repair workshops?
Q: How does VIDEX precision crimping engineering prevent micro-leaks inside delicate watch movements?
A: The standardized IEC physical dimensions for the VIDEX LR626 (AG4) cell are 6.8 x 2.6 mm with a nominal capacity of ~18 mAh. This miniature format represents the universal power standard for millions of analog quartz wristwatches, novelty rings, and miniature LED novelties. Selecting VIDEX guarantees absolute mechanical compatibility with standardized watch movement cavities.
Q: Why do analog quartz wristwatches lose time or freeze unexpectedly when powered by cheap unbranded AG4 cells?
A: Watch stepping motors draw precise micro-ampere current pulses every second; inferior cells fail to maintain stable voltage profile under load. When voltage sags below 1.2V, the second hand stutters in place or the watch falls behind by several minutes daily. VIDEX AG4 / LR626 alkaline button cells deliver flawless 1.5V voltage stability for smooth, accurate timepiece tracking.
Q: How do LR626, AG4, 377, SR626SW, and SR626 designations differ, and does VIDEX AG4 serve as a direct replacement?
A: LR626, AG4, and 626 represent 1.5V alkaline button cell geometry, whereas 377, SR626SW, and SR626 designate silver oxide equivalents. The VIDEX AG4 / LR626 serves as a 100% mechanically and electrically compatible drop-in replacement for all these designations across consumer wristwatches. It provides long operational runtime while reducing annual battery replacement costs.
Q: How does the 5-year guaranteed Shelf Life of VIDEX AG4 batteries make it the ideal choice for watch repair workshops?
A: As the world's most frequently replaced watch battery, VIDEX's factory-guaranteed 5-year shelf life allows workshops to economically stock multi-pack blisters. You can confidently store VIDEX AG4 blister multi-packs in workshop drawers without fear of parasitic self-discharge during storage. Each cell delivers 100% nominal output the exact instant it is installed inside a timepiece.
Q: How does VIDEX precision crimping engineering prevent micro-leaks inside delicate watch movements?
A: VIDEX employs a micrometrically stamped stainless steel shell mechanically crimped around a resilient nylon insulating sealing ring. This sealed capsule architecture prevents alkaline electrolyte vapor leakage from escaping onto delicate watch gears and circuit boards. Your timepieces remain fully shielded against internal chemical oxidation and mechanical ruin.
