I have a LM2102SP that is about 1.5 years old. Never had an issue. The last two times I have mowed I have had starting issues. When I try to start it I get a flashing orange light followed by an alternating flashing orange/green light. When it happened the first time I thought maybe either the battery overheated or the motor did, even though I wasn't cutting particularly high grass, the today I had the problem from the get-go. Motor and battery hadn't been used in a couple of weeks and it has been cool outside. Took several attempts to get it started. Then whenever I stopped it to empty the grass catch it would take several attempts to start it again.
