Bought this as an extra battery for my Sony AC43 camcorder. At first I was scared that I ordered the wrong one because I had an FV70A, where this one is just an FV70. But I learned the only difference is manufacturing date (FV70 made in 2010 vs FV70A made in 2015). Otherwise they fit the same and have the same capacity. Charged it to full just fine. I don't know how long this has been sitting in packaging, but it's never been used, so I'll see later on if it still holds a good charge.
