Why Choose the Original Whitlock PN:000505
- OEM Guaranteed Compatibility: Designed and tested specifically for Whitlock PLC platforms — zero integration risk.
- Certified Quality: Meets industrial-grade standards for temperature stability and discharge consistency.
- Data Integrity: Ensures uninterrupted RAM retention and RTC accuracy during power outages.
- Warranty Support: OEM parts maintain system warranty validity; third-party substitutes may void coverage.
- Long Service Life: Engineered for extended standby periods common in industrial automation environments.
Typical Applications
- PLC RAM data backup (program and parameter retention during power loss)
- Real-time clock (RTC) maintenance in automation controllers
- SCADA and DCS auxiliary backup power
- CNC machine tool controller battery replacement
- Industrial robot controller memory backup
- Building automation and energy management systems
System Compatibility
The Whitlock PN:000505 is primarily designed for Whitlock-branded PLC systems. Functional equivalents may be compatible with the following platforms — always confirm with your system documentation:
- Siemens S7-200 / S7-300 / S7-400 series
- Mitsubishi FX / Q / iQ-R series
- Omron CJ / CS / CP series
- Schneider Electric Modicon M340 / Premium
- Allen-Bradley MicroLogix / CompactLogix (verify connector)
- Beckhoff CX series embedded controllers
Selection Guide
Use the following criteria to select the correct battery module for your application:
- Step 1 — Confirm Voltage: Verify your PLC requires 3.6V (not 3.0V or 3.7V). Check the controller’s battery compartment label or manual.
- Step 2 — Check Connector Type: Whitlock modules use a proprietary connector. Confirm pin pitch and polarity before ordering a replacement.
- Step 3 — Assess Capacity Needs: Estimate backup duration required. Higher mAh = longer retention. Standard ER14250 = ~1,200 mAh.
- Step 4 — Verify Operating Environment: For high-temperature environments (>55°C), select high-temp rated lithium cells.
- Step 5 — OEM vs. Equivalent: For warranty-critical systems, use OEM PN:000505. For cost-sensitive maintenance, certified equivalents are acceptable.

Replacement & Compatibility FAQ
Q: Can I use a standard ER14250 cell to replace the Whitlock PN:000505?
A: In many cases yes, if the voltage (3.6V) and connector match. However, the OEM module includes a PCB and connector assembly — a bare cell may not be a drop-in replacement without modification.
Q: How often should I replace the PLC backup battery?
A: Typically every 3–5 years, or when the PLC displays a low-battery alarm. Do not wait for complete discharge, as this risks program loss.
Q: Is the PN:000505 rechargeable?
A: No. Lithium thionyl chloride (Li-SOCl₂) cells are primary (non-rechargeable). Replace with a new unit when depleted.
Q: What happens if the PLC battery dies?
A: The PLC will lose its program, parameters, and RTC data upon the next power cycle. Always replace proactively.
Q: Does Konmask ship internationally?
A: Yes. We ship worldwide with DHL, FedEx, and EMS. Contact us for shipping rates to your region.
