Questions about this item
How do I install the A1278 battery in my MacBook Pro 13 inch and what step do people often miss?
Remove the bottom case screws, disconnect the old battery connector, fit the new A1322 replacement, reconnect the cable, then replace the case; many forget to disconnect the battery connector before removing the old pack.
What maintenance or replacement will the 10.95V 6000mAh lithium-polymer battery need later?
The battery is sealed and maintenance-free; plan to replace it once capacity drops below usable levels, typically after several hundred charge cycles.
What limit appears first on the 65.5Wh pack during sustained heavy use?
The pack's built-in overcharge and over-discharge protection will cut power before the cells overheat, so runtime ends when the protection circuit triggers.
