Report "I have a Tornado Cordless Leaf Blower - Model #: SC845 that I purchased from Heartland America. It came with a charger but we recently moved and the unit and charger were separated. I have a charger that looks like the right one but I want to be sure before I plug it in. I looked all over the unit for specs. but I can't find any. I'm pretty sure it has a 12V battery. The charger has the correct connecter and it is part number HD-DC15-1000. In 120VAC 60Hz, Out 15VDC 1.0A How can I tell if it will charge the battery without damaging it?"
