Precautions
- Charging Voltage Limit: Do not exceed 3.3V maximum operating voltage. Overvoltage may cause leakage or permanent damage.
- Soldering Notice: Only solder through IV01E SMT tabs. Avoid direct heat contact to the cell metal casing.
- Anti‑Short Circuit: Prevent short‑circuit during handling and assembly to avoid component damage.
- Polarity Check: Confirm positive / negative polarity before power‑on; reverse charging will destroy the device.
- Reflow Profile: Follow Seiko official reflow temperature curve to protect internal cell sealing structure.
Typical Applications
- Real‑Time Clock (RTC) power backup in smart meters, security systems, and industrial controllers

Frequently Asked Questions
Q1: How does the Seiko XH series differ from standard MS rechargeable lithium batteries?
A1: XH‑series uses lithium‑capacitor technology. It supports over 10,000 charge‑discharge cycles, much higher than ~1,000 cycles of MS lithium batteries, and features faster charging for high‑cycle backup scenarios.
Q2: What does the “‑IV01E” suffix stand for in XH414HG‑IV01E?
A2: The suffix indicates factory‑pre‑welded IV01E SMT surface‑mount tabs, designed for automated PCB reflow soldering.
Q3: Does XH414HG‑IV01E need a dedicated charge controller IC?
A3: No special controller IC required. It can be powered from regulated 3.3V supply with simple current‑limiting resistor or diode‑resistor circuit.
Q4: Can I get custom terminal tabs or wire‑harness versions?
A4: Custom solder tabs, pin and wire‑assembly options are available. Please submit your requirements via inquiry form.
Q5: What is the difference between IV01E and IV02E suffix?
A5: Both share identical cell electrical parameters. IV01E and IV02E differ only in tab shape and tab position on the cell, for different PCB footprint layouts. They are not direct drop‑in replacement for each other.
Q6: What is the difference between cell‑body size and overall tab‑included dimension?
A6: Cell body: Φ4.8 × 1.4 mm (core capacitor only). Overall component dimension including solder tabs: 1.9 × 6.8 mm. Please confirm PCB footprint by overall size for layout design.
Q7: Are there drop‑in compatible alternative parts for XH414HG‑IV01E?
A7: No full pin‑to‑pin equivalent. For function‑level backup‑power replacement, compare voltage 3.3V, capacity ~0.08F, operating temperature ‑20~+60℃. Changing alternative parts requires PCB layout re‑verification.
Q8: Why do some e‑commerce platforms show 100,000 cycle‑life for this part?
A8: Official datasheet rated cycle life is >10,000 cycles. Some market platforms have typo with extra zero. Please follow original manufacturer specification for design reference.
