Battery was used 2x and now won't power the EGO Blower or Edger. I used the blower twice and charged the battery after each use. I then connected the battery to use the blower again and it wouldn't power up. It made a brief attempt at starting and the battery flashed red. I tried the battery in the EGO edger and it did the exact same thing. When I place the battery on the charger, the light flashes different colors and then goes black. The light on the charger is solid green. I've owned this less than two weeks and I'm already having these problems?!?
