Upcoming MacBook or MacBook Air battery documents will appear

A new pair of legal certifications for a potential MacBook or MacBook Air battery may indicate that a hardware refresh is imminent.

The certificates, submitted to the Chinese 3C administrator and the Danish Demko in Denmark, relate to a 49.9 watt-hour battery with model number A2389 and a capacity of 4,380 mAh. The model number has not been used yet, but the capacity corresponds to the batteries used in the current generation of MacBook Air models.

Both certifications were first noticed by Venkatesh Babu.G, a public information provider to MySmartPrice. As he notes, the voltage charging rating indicates that the battery is likely for a MacBook.

Apple already refreshed the line-up with the MacBook Air 2020 in March, but the upcoming move to Apple Silicon could mean that a new MacBook Air model will launch earlier than Apple’s usual update rate.

In March, analyst Ming-Chi Kuo predicted that Apple’s first ARM-based MacBook model could be released in late 2020.

After Apple announced the transition to Apple Silicon in June, Kuo updated that forecast to suggest that a MacBook Air with an A-series chip could debut in the fourth quarter of 2020 or the first quarter of 2021. On the other hand Kuo suggested that a 13-inch MacBook Pro with an A-series chip should debut first.

Earlier, a reliable leaker suggested that the first of Apple’s Apple Silicon Macs could be a refresh of the 12-inch MacBook.

Based on Apple’s current and recent notebook specifications, the battery indicated in the 3C and UL Demko certificates has too low a capacity for a MacBook Pro and higher than the last generation 12-inch MacBook. However, Apple may make changes to the capacity of the batteries it installs in its A Series MacBook models. With higher energy efficiency, a MacBook model may have the same battery life with a lower capacity battery.
