InfoLithium battery pack is designed specifically for use with select Sony camcorders. Carry a spare in your camcorder bag, and enjoy hours of continuous recording time. (Battery life will vary with model, usage, and temperature.) And rechargeables like this one don't lose their capacity when partially charged or discharged, so you can freshen up this battery whenever it's convenient.
InfoLithium batteries include a built-in microprocessor that communicates with compatible camcorders and allows them to display the minutes of remaining battery time in the corner of your viewfinder or color LCD screen. This handy system takes the guesswork out of figuring out when to change batteries. 3 year manufacture warranty
