Test your new battery's fit and alignment carefully before installing it.

Your replacement battery may come affixed to a thick plastic top liner to help keep the individual cells in position as you install it. Don't remove this liner until after the battery is installed.

If your battery came with adhesive pre-installed on the bottom, peel away the bottom plastic liners to expose the adhesive. If your battery did not come with adhesive, apply a thin double-sided adhesive tape such as Tesa 61395 to the lower case in the areas marked in red.

Carefully position the battery and set it into place. Press and hold each cell firmly for 5-10 seconds to secure it to the lower case. Afterward, peel off the plastic top liner along with any foam padding.
