MacBook Repair
MacBook Battery Replacement
Apple recommends MacBook battery replacement when health drops below 80%, but many users notice performance impacts well before that threshold. At Mr Gadget in Rickmansworth we replace batteries in MacBook Air (M1, M2, M3) and MacBook Pro (13", 14", 16" in all recent Apple Silicon variants) as well as older Intel models.
MacBook batteries are strongly adhered to the chassis and the trackpad sits directly above on many models, requiring careful heat application and precision levers to avoid damage. We use full-capacity cells matched to Apple's rated Wh, verify the battery cycle count resets correctly in System Information, and confirm proper charging behaviour on MagSafe and USB-C. All replacements carry a 12-month warranty.
