It was only on Sunday 23rd September that I used it on my Sony SODCRHC38 DCR-HC38 Mini DV Camcorder. I set the Camcorder to always remain on, and filmed for 3hrs and still had 1hr and 20 min of life remaining on it. I did not use any external power. In the process I changed 3 mini DV 60 min cassettes. I have no regrets buying this Battery, it is worth every cent. 1 of 1 customers found the following review helpful: Upto six hours of video recording!, 2007-09-17 This battery is great, giving me upto 6 hours of taping time.

Battery lasts over three hours on a full charge on my Sony High Def Hard Drive Camcorder (HDR-SR7). For reference, the standard battery that came with the camcorder (NP-FH60)lasts about an hour and a half. Both are referenced at continuous recording. They'll both last much longer if not used continuously. Overall I have to say that I am very satisfied with this product and would recommend it highly.
