LR1, 4LR44 and A544 batteries provide reliable and long-lasting electricity.
Compact high-voltage electronic devices often require a powerful yet small-sized power source. LR1 (N size, 1.5V) and 4LR44/A544 (6V) alkaline batteries are designed with the aim of providing stable voltage to devices with high pulse loads. These cells are widely used in car alarms, professional microphones, medical equipment, and remote controls. The optimized electrochemistry prevents voltage drops at critical moments, providing a high 800mAh (LR1) capacity. Thanks to the hermetic capsule, they are safe against electrolyte leakage over a wide temperature range.
Physical and technical parameters:
- Energy density: Specialized chemistry to deliver high-speed pulses.
- Hermetic protection: Prevents internal chemical leaks under extreme conditions.
- Wide application: From car remotes to professional measuring devices.
Precise 6V power supply guarantees high-quality and continuous operation of equipment in critical situations. Furthermore, in systems with higher voltage needs, you can always rely on the durable A23 / A27 Batteries. Safety standards require the use of only certified elements in work technologies. Properly selected components that meet technical specifications significantly extend the operating cycle of the hardware in extreme working conditions. Integrated materials engineering and rigorous quality control during the manufacturing process ensure maximum reliability and safety in all application scenarios. This approach is fundamental to today's demanding industrial and professional needs, where there is no room for error. Efficiency is always a primary requirement for any system.
Q: What is the technical difference between LR1 (N-size) and 4LR44 (A544) alkaline batteries?
Q: Why do dog anti-barking and training collars specifically use 6.0V 4LR44 (A544) batteries?
Q: In which medical and measuring devices is the compact LR1 (N-size) 1.5V format used?
Q: What is the guaranteed shelf life of LR1 and 4LR44 alkaline batteries?
Q: Can a 4LR44 (6.0V) battery be replaced with four individual LR44 (1.5V) coin cell batteries?
A: LR1 (12.0 x 30.2 mm) is a single 1.5V alkaline element with approximately 800 mAh capacity, whereas 4LR44 (13.0 x 25.2 mm) is a 6.0V block battery. The 4LR44 casing contains four micro-alkaline elements connected in series (4 x 1.5V = 6.0V), providing higher voltage in small-sized devices.
Q: Why do dog anti-barking and training collars specifically use 6.0V 4LR44 (A544) batteries?
A: Collar electrical stimulation or ultrasonic transducers require a 6.0V voltage impulse that a standard 1.5V element cannot provide. The VIDEX 4LR44 battery maintains micro-current output during the impulse, preventing voltage drop and ensuring stable operation of the collar microprocessor.
Q: In which medical and measuring devices is the compact LR1 (N-size) 1.5V format used?
A: The LR1 format is used in portable glucometers, insulin pump remotes, and micro-flashlights requiring greater capacity than AAA batteries with a shorter casing length. The 30.2 mm length allows reducing device dimensions while maintaining 1.5V alkaline electrochemical stability.
Q: What is the guaranteed shelf life of LR1 and 4LR44 alkaline batteries?
A: The alkaline electrochemical system in a sealed steel casing provides a 5-year shelf life from the date of manufacture. Stored in a dry environment at temperatures between 15°C and 25°C, battery self-discharge does not exceed 2% per year, retaining at least 90% of initial energy.
Q: Can a 4LR44 (6.0V) battery be replaced with four individual LR44 (1.5V) coin cell batteries?
A: Physically, four LR44 elements create the same 6.0V voltage and 11.6 mm diameter, but without an external insulating sleeve, there is a risk of a short circuit against the device's metal walls. Therefore, it is recommended to use a factory-assembled 4LR44 block with an integrated polymer sleeve.
