What to do if Renogy Battery Charger shows under voltage alarm?
- MMarcus BallAug 14, 2025
If you're getting an under voltage alarm on your Renogy Battery Charger, use a multimeter to check the battery voltage. Make sure the voltage isn't lower than the Battery Charger's rated specification, which requires at least 10.5 ± 0.5 volts. Disconnect the battery if needed.
