Setup and Installation
Before beginning the battery replacement process, ensure your UPS is turned off and disconnected from all power sources and connected equipment. Refer to your specific UPS model's user manual for detailed battery replacement instructions, as procedures may vary.
- Preparation: Power down the UPS and disconnect it from the AC power outlet. Disconnect all connected loads.
- Access Battery Compartment: Locate and open the battery compartment on your UPS. This may involve removing a front panel or cover.
- Disconnect Old Battery: Carefully disconnect the battery cables from the old battery cartridge. Note the polarity (+/-) if applicable.
- Remove Old Battery: Slide or pull out the old battery cartridge from the UPS. Be aware of its weight.
- Install New Battery: Insert the new APCRBC140 cartridge into the UPS compartment, ensuring it slides in completely and securely.
- Connect New Battery: Reconnect the battery cables to the new cartridge, ensuring correct polarity.
- Secure Compartment: Close and secure the battery compartment cover.
- Power On: Reconnect the UPS to the AC power outlet and turn it on. Allow the UPS to charge the new battery for at least 24 hours before relying on it for full runtime.

Operation
Once installed, the APCRBC140 functions as the power source for your UPS during power outages or fluctuations. The UPS will automatically manage the charging and discharging of the battery. Ensure the UPS is connected to a stable power source to allow the battery to remain fully charged.
- The UPS will perform self-tests periodically to check battery health.
- A new battery may not provide full runtime until it has undergone a full charge/discharge cycle.
Maintenance
The APCRBC140 is a maintenance-free sealed lead-acid battery. However, proper care of your UPS system will extend the life of the battery.
- Keep the UPS in a cool, dry, and well-ventilated area.
- Avoid exposing the UPS and battery to extreme temperatures.
- Ensure the UPS is regularly connected to power to keep the battery charged. Prolonged storage of a discharged battery can reduce its lifespan.
- Periodically perform a UPS self-test to monitor battery health.
Recycling
Batteries contain materials that must be recycled properly. Do not dispose of the old battery cartridge in household waste.
APC offers an "RBC Recycling Program" for genuine APC Replacement Battery Cartridges. This program includes free return to a recycling center. You can use the packaging from your new battery to return the old one. Visit the official APC website for details on how to participate in this program.
Troubleshooting
If you encounter issues after installing your new APCRBC140, consider the following common scenarios:
- UPS not recognizing new battery: Ensure all battery cables are securely connected and the battery compartment is properly closed. Try performing a manual self-test on the UPS.
- Short runtime after installation: A new battery requires a full charge cycle (typically 24 hours) to reach its optimal capacity. Ensure the UPS is connected to utility power for this duration.
- Battery warning light/alarm: If the warning persists after charging, verify the battery connections. If the issue continues, the UPS itself might require service, or the battery may be faulty (though rare for new genuine RBCs).
For more complex issues, refer to your UPS model's specific troubleshooting guide or contact APC technical support.
