Fits A1708 A2159 A2289 A2338 models only

The battery suits owners of MacBook Pro 13-inch units from late 2016, mid 2017, 2019 and 2020 that carry model numbers A1708, A2159, A2289 or A2338. It covers both Core i5 and Core i7 variants including Touch Bar and non-Touch Bar versions. Buyers with 15-inch or 16-inch MacBook Pro models, MacBook Air, or any non-Apple laptop cannot use this part. Older pre-2016 MacBook Pro 13-inch machines are also excluded.

54.5Wh capacity at 11.4V decides fit

The single specification that determines compatibility is the 54.5 watt-hour capacity paired with an 11.4-volt output. Your MacBook Pro 13-inch must specify this exact voltage and capacity rating for the replacement to function correctly. Verify the original battery model number printed on the cell matches either A1713 or A2171 before ordering.
