Questions about this item

What comes in the box with the KingSener A1527 battery and do I need to buy any tools or cables separately?

The package contains the 7.55V 39.71Wh 5263mAh Li-polymer replacement battery only. No tools, screws or cables are included, so reuse the original fasteners and connector from the MacBook 12 inch Retina A1534.

How do I know whether the A1527 or A1705 part number matches my 2015 2016 or 2017 MacBook 12 inch Retina?

Both A1527 and A1705 are printed on the label and replace Apple part 020-8504. Check the original battery in your A1534 — if it shows either number this unit is the correct fit.

What does the 39.71Wh 5263mAh rating mean for daily run time once the battery is installed in my MacBook?

The 39.71Wh design capacity matches the original specification, so a full charge should deliver the same operating time as a factory-new Apple battery in the 12 inch Retina model.
