Apple A2171 Replacement Battery Review
Apple A2171 replacement battery for the MacBook Pro 13-inch A2159 (2019), A2289 (2020) and the M1 A2338 (2020).
Apple does not separately publish a Wh figure for this pack; iFixit places it in the same roughly 58Wh class as the A1964. Treat the capacity here as an estimate, not a label figure, until Apple publishes one.
What to check before you buy
The same authentication and warranty rules apply as every Apple pack: fitment outside an authorised channel with a non-genuine battery is unsafe from a service-state standpoint even when it is electrically compatible.
