I bought this battery to run my 810 MPH leaf blower on a 1 ac. property. The battery lasts about 45min to 1hr running on med to intermittently high which is enough to finish the job of cleaning leaves. Now I keep the 4amp hr battery in reserve, just in case or for cleaning off the front door area and back door area. As most have said the battery is heavy but easy to handle once on the blower. Overall very satisfied with product and you must tell yourself this is a battery product, so you must buy a back up battery to have in case it runs out and you need to finish the job. Just like you run out of fuel and re fuel your gas equipment.

I bought this as an additional battery for my mower. I need two charges to finish my .6 acre lot. This battery works as expected for my lot, which is not without inclines and a lot of shrubs. I would recommend.
