First some background. Mower would flash yellow light when attempting to start. After recycling button and lever a few times it would start and run. Talked to customer service, and they are replacing the unit (9 months old, but 4 of those in storage for the winter). Now, I attempted to charge the battery in anticipation of the new mower arriving Tuesday. When I place it on the charger, the first green light on the charger flashes briefly, and then all 4 green lights come on steady. This is despite the fact that the battery has been used for at least 20-30 minutes. In other words, it appears that it will not charge. I noticed that after removing the battery and unplugging the charger the green lights stay on for a minute or two, despite not being plugged in. The battery is not completely discharged, but after 20-30 minutes use, it surely is not fully charged. I'm wondering it maybe the malfunction with the mower somehow damaged the battery, or i f the charger itself is malfunctioning. UPDATE: I did run the old mower for about 20 minutes with the battery, since it will run, but experiences the yellow overload light sometimes when attempting to start. Placed the battery on the charger, and got the same condition - one green light flashes, then all 4 go solid green. I put the battery in the refrigerator for about 10 minutes, and placed it back on the charger and it is actually taking a charge. The indicator light on the battery itself was green, and never indicated an overload/overheat condition, but now I'm wondering if the draw on the battery from the motor itself might be causing the battery to become overheated, and for some reason, the charger will not attempt to recharge it in that condition. Any ideas? I'm hoping the replacement mower will solve the problem. Guess I'll know Tuesday.
