I have three Sony Pro Cam HXR NX30 camcorders I use for my videography work and need to have extended recording capability, often shooting lengthy events. The Sony Info-LITHIUM NPF100 provides exceptional battery life. I have been using this model for several years. It's dependable and I consider it a "must have"! I highly recommend it.
