Button battery chargers guarantee safe and fast restoration of power elements.
Micro chargers capable of safely restoring lithium button cells (like the LC420 model) are a highly specific and necessary engineering solution. It uses a limited 60mA current to charge models such as LIR2032, LIR2025, and LIR2016 evenly without overheating. Independent slots provide precise process control separately for each coin, preventing the formation of overvoltage. A modern USB format for integration directly into a computer or charger block saves space and reduces the use of wires.
Physical and technical advantages:
- 60mA charging: Constant and safe current protects the internal charge of small button batteries.
- USB direct socket: Eliminates excess cables on the desk or around the computer.
- Multi-shape support: Serves LIR2032, LIR2025, and LIR2016 coin cells.
Safe and gentle charging guarantees a stable life for coin batteries, preventing the stoppage of expensive microelectronics. By restoring the charge through this node, you can ensure stable operation for your reusable LIR2032 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, guaranteeing safety.
Q: Why must rechargeable 3.6V lithium coin accumulators (LIR2032, LIR2025, LIR2450) be charged ONLY in specialized micro-current chargers?
Q: How do LIR coin accumulator chargers ensure safe shut-off upon reaching 4.20V?
Q: Why is it STRICTLY PROHIBITED to insert standard single-use CR2032 or CR2025 lithium batteries into an LIR coin charger?
Q: How does the LED indication on LIR chargers inform users about charge status and errors?
Q: What are the compact dimensions and storage safety standards for LIR coin chargers?
A: LIR series coin accumulators have a small capacity (~40–45 mAh), so their charging current must not exceed 35–45 mA (0.5C–1C rate). Attempting to charge them in standard cylindrical Li-Ion chargers supplying a 500 mA current causes the coin element to overheat within seconds, resulting in casing deformation and explosive gas leakage.
Q: How do LIR coin accumulator chargers ensure safe shut-off upon reaching 4.20V?
A: The charger's built-in microcontroller uses a narrowed CC/CV algorithm, where the voltage is strictly limited to 4.20V during the CV phase. VIDEX LIR chargers terminate current supply as soon as the charge current falls below 3 mA, preventing the degradation of the lithium coating on the anode.
Q: Why is it STRICTLY PROHIBITED to insert standard single-use CR2032 or CR2025 lithium batteries into an LIR coin charger?
A: The standard CR2032 is a single-use (Primary Lithium) 3.0V cell containing active metallic lithium and lacks a rechargeable electrochemical structure. Supplying charging current to a CR2032 rapidly increases its internal pressure, inevitably causing battery explosion and the leakage of corrosive electrolyte.
Q: How does the LED indication on LIR chargers inform users about charge status and errors?
A: The dual LED indication uses a red light during the active charging phase and a green light upon reaching 100% full charge. If a damaged accumulator or a single-use CR battery is inserted into the slot, the indicator flashes red, signaling an automatic power block.
Q: What are the compact dimensions and storage safety standards for LIR coin chargers?
A: LIR chargers are manufactured in ultra-compact casings with direct USB power (5V DC), providing a 5-year working resource. Built-in pulse-width modulation protects the power source from overload, ensuring a stable micro-current supply in home and travel conditions.
