Why The Craftsman V20 Charger Blinks Green
The Craftsman V20 battery charger blinking green can mean several things. It often shows the charger’s current status or a problem with the battery or charger. Understanding why the green light blinks helps you fix the issue quickly and safely. This section explains the common reasons behind the blinking green light.
Normal Charging Indicator
The blinking green light often means the battery is charging. It flashes while the charger sends power to the battery. This blinking is normal and shows the battery is receiving energy. Wait until the light turns solid green, which means the battery is fully charged.
Battery Not Properly Seated
If the green light blinks quickly, the battery may not be placed correctly. The charger needs a good connection to work. Remove the battery and put it back firmly. Make sure it clicks in place. A poor connection can stop the charger from working right.
Faulty Battery Connection
The blinking green light might also signal a bad connection inside the battery. Dirt, dust, or damage can cause this problem. Clean the battery terminals gently with a dry cloth. Check for any signs of damage. A faulty connection stops the charger from charging the battery properly.
Charger Malfunction
Sometimes, the charger itself can have a problem. A blinking green light may point to an internal fault. Unplug the charger and let it cool down. Try charging another battery to test it. If the light keeps blinking, the charger may need repair or replacement.

Test With A Different Battery
