My 56 Volt, 530 CFM Model LB5300 Blower Battery will not take a charge anymore. After I was using it I noticed it was going dead but the power button would not light up when pressed. When I put it in the charger, the charger light goes on and off in 1 second increments and the charger clicks at the pace of the light. The power button does not light up in charger or when pressed. I tried my battery from my EGO mower and it charges in the blower charger so I think my battery is junk? Any suggestions are appreciated!
