I own a 2 in 1 cordless li-ion grass trimmer/edger. I charged the battery to begin using it this year and after charging the green light appeared on the charger and when I put the battery in to the tool and tried to use it I had very little power to trim the grass and it even quit on me. I called the company hep number and was given a number to us on my cell phone. I tried it and got the message that the number could not be connected as dialed. I think that I need a new battery or charger but I cannot reach the company.
