Battery Charger Flashing Exclamation 

Flashing exclamation marks on the QC330 charger can occur when you switch it on or insert the battery. The exclamation mark serves as a warning or error indicator. With this sign, the battery won’t charge past two bars


Start by inspecting the contacts in the charger. Take a close look to ensure they’re in good condition. Look for any signs of scorching or debris like wood chips stuck in them. Sometimes poor contact can lead to charging problems.

Try gently cleaning the contacts with a soft cloth or small brush if you notice any issues. Ensure that they are free from any dirt or debris that might hinder proper charging. Once cleaned, give it another try and see if the flashing exclamation mark persists.

The problem can be resolved by contacting Husqvarna if the contacts appear to be in good condition.

Charger Does Not Turn On 

When you insert a battery, the charger may not turn on and the LEDs will not light up. This could be due to a couple of reasons, so let’s go through them and find a solution.


One possible cause could be a bad connection between the charger and the battery. Keep the power connectors between the charger and battery clean and free of dirt or debris. So, carefully inspect the connectors, and clean them if needed. Also, make sure they are securely connected.

Another potential issue could be a broken charger itself. To troubleshoot this, you can try the following steps:

  • Disconnect the charger from the mains power outlet and wait for at least one minute.
  • After the minute has passed, reconnect the charger to the mains power outlet.
  • Check the charger to see if the fan starts running and if the green LED light comes on. Typically, the green LED should stay on for approximately three seconds.

The charger may be faulty if the fan doesn’t start or the LED doesn’t light up at all.

In that case, you need to call a professional technician for further troubleshooting.

Flashing Red Warning Triangle 

Your battery charger may be malfunctioning if it flashes a red warning triangle when the battery is inserted. When this happens, follow the procedures for checking a broken battery charger mentioned above.

The battery charger can also flash a red warning triangle when you plug it in or during charging. Then it means the charger has gone bad and you need to replace it.

Flashing Green Light Then Red Warning Light

Your charger may be defective if it flashes green for 5-15 seconds and then turns red.

In this case, try putting on a working battery and see if the problem persists. If it does, then you need to replace your charger.

The Husqvarna QC330 battery charger is a sensitive product that needs proper handling and storage. Follow these tips for extending the lifespan of your battery and charger.

  • Avoid Non-Rechargeable Batteries: Do not attempt to charge non-rechargeable batteries with the Husqvarna QC330 charger. It is intended solely for use with compatible rechargeable batteries.
  • No Disassembly or Repairs: Refrain from disassembling or repairing the battery charger on your own. If any issues arise, consult an approved service agent for assistance.
