Want to extend the life of your MacBook Pro battery? A new offer from Apple might let you replace it for free.

Some non Touch Bar, 13-inch MacBook Pros that were manufactured between October 2016 and October 2017 are eligible for the program, and you can see if your computer qualifies by entering your serial number on Apple’s website.

The company said some of the batteries in models manufactured during this one-year period may be faulty, which is what prompted the offer. Although it’s not a safety issue, a component in the battery could fail, causing the battery to expand. Affected customers who already paid to have their battery replaced can also contact Apple for a refund.

The service takes three to five days to complete and can be done at any Apple-authorized service provider or retail store. Computers can also be mailed in to a repair center.

Before sending it away for repairs, though, it's important to check for other issues with your computer. Apple notes, “If your 13-inch MacBook Pro has any damage which impairs the replacement of the battery, that issue will need to be resolved prior to the battery replacement. In some cases, there may be a cost associated with the repair.”
