Curb find: Greenworks 25302 cordless mower + charger + 1 battery (not 2). Charged the battery but the mower won't start. The safety key is in. When I insert the battery, the red LED light next to it does not light up. I removed the cover and everything seems to be connected properly, at least I am not seeing anything that's obviously disconnected.
1. Can it even run with just one battery?
2. If it can, what can be wrong with the mower?
TIA!
