Upgrade from a depleted or failing original pack

Swap this unit in when the factory battery no longer holds a useful charge or shows swelling. The jump is worth it if runtime has dropped sharply or the laptop shuts down unexpectedly on battery power. The supplier notes that the listed part numbers are compatible with each other despite voltage differences, so any variant supplied will work.

Verify your original part number

Check the sticker on your existing battery for one of the listed part numbers, or confirm your laptop is an Air14+ ACH, ITL or ACN 2021 model. The compatibility list is non-exhaustive; if your part or model number is absent, contact the seller to confirm fit before purchase.
