Howdy everyone! I ran the weedeater this a.m. until my battery ran out of juice. Tried to put it on the charger but couldn't get the charger's light to show 'green.' It kept blinking red. That means the battery isn't put in correctly. Dang! I tried and tried and couldn't get it to work. So I'm out of commission with the weedeater.
Batteries do that sometimes if you try charging them when they're hot, like right after using. Might need to just cool down.
