If the charger detects a weak or damaged battery, the charging indicator (24) will flash red at a fast rate.

Follow these steps: 

• Re-insert the battery (22).
• If the charging indicators continues flashing red at a fast rate, use a different battery to determine if the charging process works properly. 
• If the replaced battery charges correctly, the original battery is defective and should be returned to a Service center for recycling.
• If the new battery gives the same indication as the original battery, take the charger to be tested at an Authorized Service Center.

You can find your nearest Service Center here or if you are in the Republic of Ireland, click here. 

Note: It may take around 30 minutes to determine that the battery is defective. If the battery is too hot or too cold, the LED will alternately blink red, fast and slow, one flash at each speed and repeat.

Should you require a new charger, these can also be purchased through the Authorized Service Centers.
