⚙️ Fit Notes
- Match your original battery part number whenever possible
- Confirm your original battery is a 6V backup battery assembly
- Confirm the connector is the correct 2-pin brown connector style
- This brown connector version replaces the discontinued black connector style
- Match the voltage, connector type, polarity, wire routing, and battery pack configuration with your original battery
- Battery replacement should be performed carefully to avoid memory loss, parameter loss, or machine setup loss
- For many industrial control systems, the backup battery should be replaced while the control has power applied, following the machine manufacturer’s service procedure
- If the system already displays a battery alarm, low battery warning, or has lost parameters, additional setup or parameter restoration may be required after battery replacement
- Do not short, puncture, recharge, crush, overheat, or dispose of lithium batteries improperly
- Always follow proper ESD, battery handling, and machine service procedures during replacement
