Hi Darren, and thank you for your post. A continuously flashing green charger can indicate a couple different things. What happens when the battery is inserted in the charger? Is it flashing green continuously when charging or just when it's first plugged in? We'd love to troubleshoot with you further, so if you could either send an email to firstname.lastname@example.org with your contact number so that one of our EGO specialists can get back to you; -or- give us a call back at 855-346-5656 today so we can help you out.
