Sony NP-FH100 Infolithium H Series High Capacity Camcorder Battery, 27 July 2010
I have used this NP-FH100 Infolithium H Series High Capacity Camcorder Battery only twice and each time it has suddenly discharged itself during use. I charged the battery fully on receipt as per the Sony Operating Instructions and then used it; it lasted approximately 2 hours before suddenly discharging. I re-charged the battery a few days later and on using it aagain the same thing happened. I believe it is a "one-off" as I have 2 more of these batteries (purchased in July 2009 via Amazon) and both work perfectly, giving me about 6 hours of use each.
I will be returning this battery to Amazon so that I can receive a replacement.
