Apple has said that “some batteries” in its range of MacBook and MacBook Pro laptops have “performance issues”.
The company has issued a software update to fix the issue and has offered to replace defective batteries.
“The factors causing the performance issues do not present a safety risk. You may continue to use your current battery,” the company said.
The main issue is to do with the batteries becoming hot and deformed
Apple has said users should contact their local Apple store or retailer and the firm will arrange replacement batteries free of charge.
Other symptoms of battery problems include:
- The battery is not recognised
- The battery will not charge and runs down quickly

Fortunately this is not that same issue as reported back in November of last year. See here for more on that.
