MacBook Pro 16" Battery Replacement in Rickmansworth
MacBook Pro 16" carries Apple's largest MacBook battery — 100Wh, the maximum allowed on commercial flights. Rated for up to 22 hours, these cells still degrade over time, especially under sustained M3 Max or M4 Max video rendering or machine learning workloads. At Mr Gadget we replace MacBook Pro 16" batteries.
MacBook Pro 16" battery replacement is one of the most involved MacBook repairs due to the large chassis, active cooling, and 100Wh cell. We take the time required and verify all Thunderbolt 4 ports, HDMI, SD card, and ProMotion display after every replacement.
