Product Description
The NP-FS11 is an "S" series InfoLithium battery designed specifically for use with select Sony camcorders, providing up to 65 minutes of recording time. However, operating time will vary depending on the device, usage, and temperature. Part of Sony's AccuPower system, InfoLithium batteries include a built-in microprocessor that communicates with Handycam models. The AccuPower Battery Meter, a highly sophisticated power management feature that constantly monitors shooting conditions, displays the minutes of remaining battery time in the corner of your viewfinder or color LCD screen. It takes the guesswork out of figuring out when to change batteries! InfoLithium batteries don't suffer from the "memory effect" of NiCad batteries, so you can partially charge them without reducing their capacity. And they're quick charge-capable when used with a compatible Sony quick charger. The NP-FS11 is rated at 3.6V, 4.1Wh. Dimensions: 2"H x 1-1/4"W x 11/16"D. For compatibility information, please see the owner's manual supplied with your camcorder.
