Before installing a new battery, remove all remaining adhesive from the MacBook Pro's case. Peel off any large strips of adhesive using tweezers or gloved fingers. Scrape away any remaining chunks of adhesive with a plastic tool, and clean the underlying areas with adhesive remover or isopropyl alcohol. To prepare your MacBook Pro for service, please backup your data. Note: 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.

About battery cycles

15-inch MacBook Pro Battery Recall Program Apple has determined that, in a limited number of older generation 15-inch MacBook Pro units, the battery may overheat and pose a fire safety risk. Affected units were sold primarily between September 2015 and February 2017 and product eligibility is determined by the product serial number.

When you use your Mac notebook, its battery goes through charge cycles. A charge cycle happens when you use all of the battery’s power—but that doesn’t necessarily mean a single charge.

For example, you could use half of your notebook's charge in one day, and then recharge it fully. If you did the same thing the next day, it would count as one charge cycle, not two. In this way, it might take several days to complete a cycle.

Batteries have a limited amount of charge cycles before their performance is expected to diminish. Once the cycle count is reached, a replacement battery is recommended to maintain performance. You can use your battery after it reaches its maximum cycle count, but you might notice a reduction in your battery life.

Knowing how many charge cycles your battery has and how many are left can help you determine when a battery replacement is required. For best performance, replace your battery when you reach its maximum cycle count.

Follow these steps to access information about your Mac notebook battery, including its cycle count:

1. Hold the Option key and click the Apple  menu. Choose System Information.
2. Under the Hardware section of the System Information window, select Power. The current cycle count is listed under the Battery Information section.
