Precautions
- Strict Charging Voltage Control: Charge within 3.1V ±0.15V. Voltage over 3.3V may cause electrolyte deterioration, capacity drop or cell swelling.
- Reflow Soldering Rules: Follow official SMT temperature specifications. Avoid direct high-temperature heating on battery housing to protect internal sealing.
- Avoid Reverse Charging & Short Circuit: Maintain correct polarity on PCB. Short circuit will trigger large current and permanent internal damage.
- Soldering Notice: Only solder on factory IV01E tabs. Do not solder directly to cell case, which may break sealing gaskets.
- Disposal Requirements: Do not burn, crush, disassemble or heat above 60°C. Dispose in accordance with local lithium battery recycling regulations.
Typical Applications
- Real-Time Clock (RTC) power backup in smartwatches, fitness trackers, and wearable IoT electronics

Frequently Asked Questions
Q1: Is ML414H-IV01E rechargeable?
A: Yes, it is a rechargeable lithium manganese dioxide coin cell, designed specially for trickle charge memory backup circuits.
Q2: What does “IV01E” stand for in model ML414H-IV01E?
A: IV01E refers to factory welded SMT surface mount tab layout, suitable for automated PCB pick-and-place and reflow soldering.
Q3: How to design the charging circuit for ML414H-IV01E?
A: Adopt constant voltage charging with current-limiting resistor and blocking diode. Keep charging voltage stable at 3.1V ±0.15V. Do not exceed 3.3V.
Q4: Are custom battery tabs or wire terminals available?
A: Yes. Besides standard IV01E tabs, alternative tab shapes and pin assemblies can be customized upon request.
Q5: Are there alternative or compatible replacement models?
A: ML414H (without suffix) shares identical cell specs, but without SMT IV01E tabs. If SMD soldering is required, IV01E version must be selected. Non-tab bare cells cannot be directly replaced for automated assembly.
Q6: What is the service life and cycle performance?
A: It supports ≥300 charge-discharge cycles under 10% DOD, ideal for long-term RTC & SRAM continuous backup application.
Q7: Can I solder directly on the battery metal case?
A: No. Only solder on factory IV01E tabs. High temperature directly on cell shell will break internal sealing and cause leakage or swelling failure.
Q8: What temperature range can this battery work within?
A: Operating temperature: -20℃ ~ +60℃. Recommended storage environment: 10℃ ~ 30℃, humidity ≤60% for extended shelf life.
