AG13 and LR44 batteries provide reliable 1.5V power to microelectronics.
AG13 or LR44 standard button cells are the most commonly used 1.5V alkaline elements in engineering and medical equipment. With an impressive 158mAh capacity, they provide excellent longevity for high-precision digital calipers, laser pointers, and glucometers. The cell diameter of 11.6 mm and height of 5.4 mm strictly comply with industry standards, preventing contact play. Produced without hazardous heavy metals, they ensure safe disposal, while the steel outer capsule maintains maximum hermeticity, eliminating oxidation processes inside expensive devices.
Physical and technical advantages:
- 158mAh capacity: Maximum energy amount in the LR44 battery category.
- Protection: A strict 11.6 mm steel ring isolates the electrodes.
- Stable voltage: Ensures precise calibration of digital measuring instruments.
Reliable microbatteries provide a long service life and precise technological operation support for professionals. For devices requiring the LR43 format, we also offer AG12 / LR43 Batteries models for maximum safety. 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 are the standard IEC dimensions and typical capacity of an AG13 / LR44 battery?
Q: Why is it essential to use precisely high-quality LR44 batteries in digital calipers and micrometers?
Q: How are LR44 batteries connected in children's sound toys and why must they be replaced simultaneously?
Q: In which specific lighting fixtures are AG13 / LR44 elements most frequently used?
Q: How to ensure AG13 battery contact protection when inserting them into a device compartment?
A: The physical dimensions of the AG13 battery are exactly 11.6 mm in diameter and 5.4 mm in thickness, making it one of the most massive coin cell elements. This geometry allows fusing about 150 mAh of energy capacity into the housing at a 1.5V voltage, which is necessary for devices with medium and heavy micro-loads.
Q: Why is it essential to use precisely high-quality LR44 batteries in digital calipers and micrometers?
A: The measuring instrument's optical sensor operates in continuous standby mode even when turned off. Low-quality elements experience a rapid voltage drop, causing LCD screen flickering and erroneous calibration readings. VIDEX LR44 batteries provide a stable current supply (Low Self-Discharge), guaranteeing accurate measuring tool operation in high humidity and dust conditions.
Q: How are LR44 batteries connected in children's sound toys and why must they be replaced simultaneously?
A: Speaker piezo elements and electric motors in toys require a 4.5V voltage, so three LR44 batteries are connected in series (3 x 1.5V). If only one element is replaced, the difference in internal resistance causes the old battery to overheat or leak, therefore all three elements must be replaced synchronously as a single block to equalize the load.
Q: In which specific lighting fixtures are AG13 / LR44 elements most frequently used?
A: This battery format dominates in mini laser pointers and portable LED light strings (such as bottle cork strings). A laser diode requires a strong initial impulse (over 4.0V, using 3 elements), which the AG13 alkaline system can maintain sufficiently long before a voltage drop that reduces beam intensity.
Q: How to ensure AG13 battery contact protection when inserting them into a device compartment?
A: The LR44 battery housing (flat surface and edges) is the positive (+) pole, while the bottom small bump is the negative (-). When inserting multiple batteries into a metal tube (e.g., a laser), indicated polarity must be followed and side contact avoided, which is why in high-class devices the battery compartment is isolated with a plastic insert.
