Lir2032 rechargeable batteries guarantee stable and efficient power supply in difficult working conditions.
Lithium-ion (Li-Ion) coin cell rechargeable batteries stand out with their compact format (20x3.2mm) and the ability to provide a high 3.6V voltage with recharging capability. These elements, with a capacity of 75mAh, perfectly replace disposable primary cells in systems where space saving and long-term operation are critical. Equipped with a 60mA standard charging current parameter, they are ideally suited for IT memory modules, telemetry sensors, smart home sensors, and compact electronics.
Physical and technical features:
- Compact size: Standard 20x3.2 mm dimensions for precise fit.
- 3.6V voltage: Provides higher current compared to standard CR.
- Sustainability: Repeated charging optimizes resource consumption in the long term.
The transition to rechargeable 3.6V coin cells is an engineering rational step to reduce the maintenance costs of smart systems. In cases where non-rechargeable 3V versions are required for standard sensors, choose our CR Lithium 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.
Q: What is the main technical difference between the rechargeable LIR2032 and the single-use CR2032 battery?
Q: Why must the LIR2032 only be inserted into micro-devices whose microchip supports a 4.2V input voltage?
Q: In which specific devices does the use of the rechargeable LIR2032 provide the greatest economic benefit?
Q: With what type of charger should the LIR2032 lithium accumulator be properly and safely charged?
Q: What is the storage term and self-discharge parameters of the LIR2032 accumulator in a resting state?
A: The LIR2032 is a rechargeable lithium-ion accumulator with a nominal voltage of 3.6V (up to 4.2V fully charged), whereas the CR2032 is a 3.0V single-use element. The LIR2032 provides approximately 45 mAh capacity and over 500 charge cycles, but its higher operating voltage can damage equipment strictly designed for a 3.0V limit.
Q: Why must the LIR2032 only be inserted into micro-devices whose microchip supports a 4.2V input voltage?
A: A fully charged LIR2032 cell reaches 4.2V, which is 40% more than the standard CR2032 3.0V nominal. If the device's microcontroller lacks a built-in voltage regulator, the high voltage of the VIDEX LIR2032 can burn out sensitive memory circuits or wireless transmitters.
Q: In which specific devices does the use of the rechargeable LIR2032 provide the greatest economic benefit?
A: The LIR2032 is advantageous in devices with high current consumption, such as rechargeable solar-powered wristwatches, microcontroller development boards (Arduino/ESP32), and Bluetooth sensors. In such applications, 500+ charge cycles eliminate the need to regularly buy single-use 3.0V elements.
Q: With what type of charger should the LIR2032 lithium accumulator be properly and safely charged?
A: Charging the LIR2032 requires a specialized CC/CV (Constant Current/Constant Voltage) charger with a limited charging current of up to 35–45 mA. Charging with standard NiMH or large-size Li-Ion chargers will cause cell overheating, electrolyte evaporation, and casing deformation.
Q: What is the storage term and self-discharge parameters of the LIR2032 accumulator in a resting state?
A: Li-Ion coin accumulators are characterized by a self-discharge of up to 5–10% per month, so their resting storage term until a preventive recharge is 5 years. To prevent the cell's deep discharge below 2.7V, which irreversibly reduces capacity, resting accumulators must be recharged once every 6 months.
