It charged right up and seems to be working great, though how do you know until the power goes out? It has a great app that is also user-friendly. I did test it running my chest freezer all night while I slept, and in the morning it was only down to 80%, though freezers turn on and off. I got this extra battery to add to the Delta 2 bcuz I'll want to watch tv at night if the power is out, movies at least. I'm ordering another extra battery for the power tower trio on my Delta 2 and my Delta 2 Max.
