To ensure the health and reliability of your Pump Partner backup power system, we recommend performing a discharge test once a year. This test will help assess the battery’s condition and verify that it can provide power during an outage.
Tools Needed:
- Electric space heater (1500W recommended) or
- Electric kettle (1200W–1500W)
- Power meter (optional, for monitoring energy usage)
Test Procedure:
1. Preparation:
- Ensure Pump Partner is fully charged (check battery level on LCD screen).
- Unplug any connected sump pump to avoid interference.
2. Connect the Load:
- Plug the electric heater or kettle into the Pump Partner output.
- If using a heater, set it to high power (1500W) for maximum discharge rate.
3. Start the Test:
- Turn on the heater or kettle.
- Monitor the operation and ensure the power is stable.
4. Monitor Runtime:
- Observe the Pump Partner LCD display to monitor:
Remaining battery percentage
Output power (Wattage)
Estimated runtime
- The expected runtime for a 1500W load should be 1.2–1.4 hours if the battery is in good condition.
- If the system shuts down significantly earlier than expected, the battery may need maintenance or replacement.
5.Record Results:
- Note the total runtime and compare it to previous years to track battery health.
- If runtime drops below 70% of the original value, consider battery service or replacement.
6.Recharge the Battery:
- After the test, reconnect the Pump Partner to the grid to fully recharge.
- Reconnect your sump pump to ensure normal operation.
Why This Test is Important?
※ Ensures backup power readiness before an actual emergency.
※ Identifies battery degradation early, preventing unexpected failures.
※ Keeps your home protected during storm seasons and outages.
Recommendation: Perform this test annually to maintain a reliable backup power station for your sump pump!
