Questions about this item

Does the Beisite A1527 battery include the pentalobe screwdrivers needed to open the MacBook 12" Retina A1534?

The battery is supplied as a standalone unit. The pentalobe and tri-wing screwdrivers required for the A1534 bottom case and battery connector must be purchased separately.

Which part number should I match — A1527 or A1534 — when ordering a replacement for my Mid 2017 MacBook 12" Retina?

Match A1527 on the old battery label; A1534 is the laptop model identifier. This cell carries part numbers A1527, A1705 and the EMC 2746, 2991 and 3099 variants used in 2015‑2017 machines.

What does the 39.71 Wh rating mean for daily runtime on a MacBook 12" Retina A1534?

39.71 Wh matches the original factory capacity, so a healthy unit restores the same typical web-browsing and video-playback runtime the notebook delivered when new.
