Battery life detail
Removable Type II nickel-metal hydride battery. Apple's product description claims 2–4 hours; the developer note claims 4.5 hours, while the later service manual gives approximately 2–3 hours. Service weight is 2.1 kg with a battery; its paired 4.8 lb figure is inconsistent. Dimensions are rounded from Apple's 10.9 × 8.5 × 1.5 inch support table; the service manual swaps width/depth and pairs 1.5 inches with 36 mm
