Query: Sony NPFH100

As stated earlier...the price is quite high for a battery, though Amazon does have a price that is better than most brick n' mortar stores and other online sites. I purchased one for my SR300 as a backup battery. The NPFH60 that came with the camera was nice...but not enough capacity for extended trips. Having these two batteries charged up ready to go before a week or two week long trip will provide ample power. It does stick out the back of the camera a bit...but I can overlook that for the extended battery life! If using a Sony cam, I would recommend this product as it gives much more power than the lower NPFH batteries.
