Direct replacement for MacBook Pro 16-inch A2991

The KingSener A2976 is a 99.6Wh lithium-ion battery built to match the original specifications of the late 2023 MacBook Pro 16-inch models MRW13LL/A and MRW63LL/A. It delivers 8607mAh at 11.57V using high-quality cells and PCB for stable capacity and longer running time. The unit is brand new and sized identically to the factory battery for a direct fit.

Restores full runtime on worn

This replacement is intended for owners whose factory pack no longer holds a useful charge or has physically expanded. The jump is worth it when the original cell chemistry has degraded after hundreds of cycles and the system reports service-recommended status. It is not for buyers who want a higher-capacity upgrade beyond the 99.6Wh design limit or who need a second battery for hot-swap use.

Verify model A2991 and original battery appearance

Confirm the laptop model number A2991 printed on the bottom case and compare the original battery layout with the product photos to ensure connector placement and screw-hole alignment match. The pack is engineered for that specific chassis; other 16-inch generations use different internal arrangements. Charge the new unit above 80 percent at least once a month if stored long term.
