AG12 and LR43 batteries provide reliable 1.5V power to microelectronics.
AG12 or LR43 button cells with 1.5V voltage are specially adapted for equipment that requires a small but constant current flow. These cells with 113mAh capacity offer excellent standby and working resources for remote controls, small stationary clocks, and medical thermometers. Its even discharge curve guarantees that the equipment does not fail to work at the most critical moment, while the 0% mercury content meets the most modern green technologies.
Physical and technical advantages:
- 113mAh resource: For long-term performance in medical devices and remotes.
- Constant flow: Does not overload the equipment's electronic circuit.
- 4.2 mm height: Universal standard for compact niches.
Stable energy flow makes this power format an integral part of modern compact devices. For even more compact needs in 7.9 mm devices, you can safely switch to the precise AG11 / LR721 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 are the physical parameters and niche applications of the AG12 / LR43 battery?
Q: Why is the LR43 format still used in older generation glucometers and blood pressure monitor screens?
Q: Can an AG12 battery be technically replaced by the thicker AG13 (LR44)?
Q: Why are LR43 batteries chosen for large pocket watches and analog chronometer mechanisms?
Q: How does storage temperature affect the self-discharge of an AG12 (LR43) battery?
A: According to the IEC standard, the dimensions of the AG12 are 11.6 mm in diameter and 4.2 mm in thickness, making it thinner than the popular LR44 model. This 1.5V alkaline battery offers approximately 100 mAh capacity, which is a justified solution for equipment that requires a wide contact but lacks sufficient space for thicker elements.
Q: Why is the LR43 format still used in older generation glucometers and blood pressure monitor screens?
A: The glucometer test strip reading sensor and LCD screen demand flat voltage output for precise measurement. Although the capacity is lower than LR44, VIDEX LR43 batteries provide a linear 1.5V voltage at low loads (pulsed), preventing the screen from fading out at crucial moments.
Q: Can an AG12 battery be technically replaced by the thicker AG13 (LR44)?
A: No, the thickness difference (4.2 mm versus 5.4 mm) is critical in precision microelectronics. Attempting to squeeze a thicker LR44 battery into a socket designed for an AG12 can irreversibly deform the copper contact bridges or break out the plastic cap's thread mechanism.
Q: Why are LR43 batteries chosen for large pocket watches and analog chronometer mechanisms?
A: More massive quartz mechanisms with additional backlight or alarm functions demand greater current output (mA) than small watch elements can provide. The AG12 / LR43 alkaline battery is capable of powering mechanical stepper motors while maintaining a parallel load for the acoustic piezo speaker.
Q: How does storage temperature affect the self-discharge of an AG12 (LR43) battery?
A: The optimal storage environment for alkaline elements is a dry place at a temperature of 15-20°C. If batteries are exposed to heat (above 30°C), internal chemical reactions accelerate, increasing self-discharge by 5-10% per year, whereas under proper conditions the LR43 retains energy throughout its 3-year guaranteed shelf cycle.
