This compares definitions, not sellers' quality. Apple's new-battery statement on this page concerns refurbished iOS devices, not every refurbished product.
Read the exact program promise
Apple's US page says its Certified Refurbished products include a one-year limited warranty, and refurbished iOS devices get a new battery and outer shell. These are Apple's program terms, not a universal definition of refurbished.
Apple's preowned-iPhone guide recommends checking battery health, return terms and lock status. It says not to buy an Activation-Locked device. Available parts-history information depends on model and software.
Our checklist: record the battery standard, parts policy, functional tests, return window and legal warranty provider. Treat an 'excellent condition' label as a question to clarify, not a battery-health measurement.
