Questions about this item

How do I install the 63.5Wh Li-Polymer battery in my MacBook Pro 13 A1278 Mid 2010, and which step do people often miss?

Remove the bottom case using the two included screwdrivers, disconnect the old battery connector, fit the new 6-cell pack, reconnect the cable, then reattach the case screws — many forget to reconnect the battery data cable before closing the lid.

What maintenance or replacement will the 63.5Wh Li-Polymer battery need after extended use?

The pack is rated for about 500 recharge cycles; once capacity drops below usable levels you simply swap the entire 6-cell Li-Polymer unit using the same two screwdrivers supplied in the box.

What limit appears first when the 63.5Wh Li-Polymer battery runs under sustained load in a MacBook Pro 13 A1322?

The 10.95V 63.5Wh cell chemistry and built-in protection circuit will trigger over-current or thermal cut-off before the 500-cycle lifespan is reached during continuous heavy discharge.
