This 61.6Wh lithium-polymer battery operates at 11.55V and delivers 5150mAh of capacity.

No Bundled Accessories or Software Included

Users must reuse existing hardware from the original battery or source mounting components separately. No firmware updates or calibration utilities are bundled with this product. The replacement is a purely hardware swap.

61.6Wh Capacity for Standard Mobile Workloads

The 61.6Wh rating supports typical office tasks, web browsing and media playback for several hours depending on system configuration and screen brightness. Demanding workloads such as sustained gaming, video rendering or heavy multi-tasking will deplete the charge more quickly. The battery is not designed for extended off-grid use without access to mains power.
