Uzlādējamās LIR 2032
Did you know that some modern devices (such as solar garden lights, computer memory backup, or certain smart keys) require rechargeable button batteries? VIDEX LIR 2032 is a Li-Ion technology rechargeable cell in a flat format.
Benefits of using LIR2032:
- Ecological and smart approach: No need to throw away the battery after it discharges; simply recharge it in a special charger or let the device charge it.
- 3.6V voltage: Provides higher power than regular disposable CR2032 (3V) batteries.
- Long service life and charging cycle time.

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.
