MacBook Air 13" A1466 (2012–2017) Battery Replacement
Compatible models: A1466, EMC 2559, 2632, 2925, 3178
The MacBook Air 13-inch A1466 had a production run of five years, making it one of the longest-running MacBook configurations Apple sold. It is still one of the most common MacBooks in daily use, appearing in workplaces, universities and households across the UK. The 54Wh battery is robust, but after years of daily charge cycles it has almost certainly lost significant capacity. Many A1466 users are surprised by how much the machine improves after a battery replacement, particularly if they have been accepting reduced runtime as normal.
- Turnaround: Same day where possible, subject to stock and workload
- 6-month warranty on the replacement battery
