Sony's NP-F970 Info-Lithium Battery Pack is a compact and lightweight option that offers the benefits of lithium-ion technology. Thanks to this technology, the battery can be charged or discharged at any time without developing memory effect. As a result, the battery never loses its full charge capacity. The battery's remaining time is displayed on the LCD and viewfinder, as it continuously communicates with the camcorder. With a recording time of up to 18 hours, the NP-F970 battery is ideal for extended filming sessions. Additionally, the battery packs come equipped with a microprocessor that accurately calculates the remaining battery life in minutes.
