Whether you have an engine-driven or battery-powered home generator, battery maintenance is vital to ensure your generator starts and provides power correctly.
How to check your generator battery using a load tester
- Disconnect the battery from the generator, remove cables and clean the battery terminals. Take a voltage reading for reference.
- Attempt to charge the battery with a 12-volt battery charger. Wait until the battery is fully charged, as indicated by the charger.
- Wait 30 minutes and take a second voltage reading.
- Wait 12 hours, do not load the battery during this time. After 12 hours take another voltage reading.
- Finally, reconnect the battery to the generator and take a reading while you start the generator. If the voltage reading drops significantly, below 9.6 volts, you may have a bad battery.
You can also use a load tester in step 5. This will provide a constant load, which will give you a more accurate assessment of the battery’s status.
