The Apple products can notice issues in the battery power if a user does not charge the batteries of the Macbook devices before it drops below 20% power. If they, i.e., lithium-ion batteries, are kept like this for over 48 hours, battery drainage is possible highly.

It is important to store MacBook devices before they drop below 50% since most of them run on lithium-ion batteries. If you are storing the Mac device you own for many months, charge it up to 50% after 6 months each. These would keep their battery capacity intact.

Follow the documented instructions for other types of MacBook batteries during proper storage to avoid battery drainage.

How to do this?

Step 1: Choose the Apple menu on the top-left side of the screen.

Step 2: Then, keep holding the OPTION key down.
