Apple has not designed the battery in these systems to be replaced by end users. Although the repair process certainly is not easy, it also is not quite as difficult and wasteful as it is for the 15-Inch Retina Display MacBook Pro models. Multiple 13-Inch Retina Display MacBook Pro notebooks share the A1425 and A1502 Model Numbers but have different batteries. Consequently, the best way to identify them uniquely enough for the purpose of replacing the battery is either by external EMC Number or by the Model Identifier in software (assuming that it will boot). Formally, when the battery no longer holds a sufficient charge it is necessary to provide Apple with the entire notebook to have the battery replaced.

Bit Driver and Specialty Bits: In the course of this repair you will encounter several rather uncommon screw types, so we’ve included all the necessary specialty bits as well as a screwdriver in the Fix Kit option. iFixit adhesive remover is highly flammable. Perform this procedure in a well-ventilated area. Do not smoke or work near an open flame during this procedure.

All 13-Inch Retina Display MacBook Pro models have an integrated lithium-polymer battery.
