Sony NP-SA100 Battery is a rechargeable lithium-ion battery designed for compatible next-generation Sony cameras, particularly models that require higher energy capacity than the previous NP-FZ100 series. It has a nominal capacity of 2670 mAh, equal to 20.9 Wh, with a mean voltage of 7.82 V, and a compact size of approximately 24.6 × 38.4 × 51.8 mm with a weight of about 89 g. The increased capacity is intended to support longer photo and video shooting sessions, especially with high-resolution cameras, advanced video recording, advanced autofocus, and processing functions that require higher power consumption. The NP-SA100 supports charging through compatible cameras or with the dedicated Sony BC-SAD1 charger, and integrates the Battery Health Check system, which allows the battery condition to be checked on compatible devices. As this is a specific battery for selected Sony camera bodies, compatibility should always be verified before purchase, as it is not automatically interchangeable with NP-FZ100 batteries. It is suitable as a main or spare battery for photographers and videographers who need additional runtime and stable power during working sessions, field productions, travel, or continuous shooting.
