AG and LR batteries provide reliable 1.5V power to microelectronics.
The Alkaline button battery series combines high 1.5V voltage stability with a compact, safe steel casing. These microscopic power sources are produced using a 0% mercury and cadmium formula, guaranteeing compliance with the highest ecological and technical safety standards. The AG series covers 13 different diameter and height standards capable of delivering capacities from 10mAh to 158mAh. This broad compatibility makes them an essential component for the maintenance of fine mechanics, electronic calipers, watches, and small diagnostic sensors. The optimal chemical structure prevents corrosion throughout storage and operation.
Physical and technical advantages:
- 0% Mercury: Completely safe chemical composition for modern electronics.
- Alkaline formula: Excellent capacity in a small format for long operating times.
- Hermeticity: Metal housing protects AGainst environmental impact.
Choosing button cells with an Alkaline formula significantly reduces equipment calibration errors, guaranteeing flawless diagnostics. In cases where a specific LR44 size is needed for expensive tools, choose the corresponding AG13 / LR44 Batteries. Safety standards require the use of only certified and tested elements in the equipment. Properly selected components that meet technical specifications significantly extend the operating cycle of the hardware in extreme working conditions. Careful selection of materials and engineering during the manufacturing process ensure maximum reliability and safety in all technical application scenarios. This analytical approach is fundamental to today's demanding industrial needs, where there is no room for error and where energy efficiency is always a primary requirement for any reliable system. This allows for significant resource savings in the long run.
Q: What is the difference between alkaline (LR) and silver oxide (SR) coin cell batteries?
Q: What does the "0% Hg" marking on coin cell batteries mean?
Q: Why shouldn't coin cell batteries be stored loosely together in a single box?
Q: How to correctly measure the remaining voltage (V) of a coin cell battery with a multimeter?
Q: Why is it dangerous to mix coin cell batteries from different manufacturers or new and used ones in the same device?
A: LR (Alkaline) batteries use zinc and manganese dioxide (Zn/MnO2) electrochemistry, which provides economical energy output for everyday devices. SR (Silver Oxide) batteries use more expensive silver oxide, guaranteeing a very flat discharge curve throughout the cycle. LR elements are an optimal solution for toys and calculators, where voltage drop at the end of load does not affect the basic function.
Q: What does the "0% Hg" marking on coin cell batteries mean?
A: It means that the toxic heavy metal mercury (Hg) is not used in the production of the element, fully complying with EU RoHS and REACH directives. Historically, mercury was added to stabilize the zinc anode against gas formation, but in VIDEX AG series batteries, it is replaced by advanced metal alloy technology that ensures airtightness without environmental pollution risks.
Q: Why shouldn't coin cell batteries be stored loosely together in a single box?
A: When the positive (flat top) and negative (bottom bump) poles of coin cell batteries touch, a massive short circuit occurs. As a result, rapid battery overheating and complete energy discharge occur within just a couple of hours. Spare elements must always be stored in their original blister packaging, which isolates the contacts.
Q: How to correctly measure the remaining voltage (V) of a coin cell battery with a multimeter?
A: The measurement must be taken under nominal load, because an empty alkaline battery at rest often shows a seemingly full 1.5V. As soon as the element is connected to a device, the real voltage drops rapidly below 1.1V due to internal resistance. Multimeter probes must press firmly against both poles, as fingerprints or oxide film on the battery surface can create false measurement resistance.
Q: Why is it dangerous to mix coin cell batteries from different manufacturers or new and used ones in the same device?
A: Elements of different series or wear levels have different internal resistance and capacity (mAh). In a series circuit (e.g., 3 batteries in a laser pointer), the weakest element will discharge first, and the stronger batteries will attempt to charge it, causing rapid overheating, outgassing, and corrosive electrolyte leakage onto device contacts.
