Apple A1964 Replacement Battery Review
Apple A1964 replacement battery, the 11.41V 58Wh pack for the MacBook Pro 13-inch A1989 (2018-2019) and A2251 (2020) chassis.
Apple's battery service state and health reporting depend on genuine parts and authorised fitting. A non-genuine pack here is out of warranty and can trigger a persistent service message, which is why we mark unauthorised pairings as unsafe rather than a soft warning.
What to check before you buy
macOS reports battery health and cycle count against Apple's own authentication, so a third-party pack that is electrically correct can still show a permanent service warning. Genuine Apple parts fitted by an authorised provider are the only pairing we would call confirmed.
