How should adhesive be secured to new batteries during installation?

Securing adhesive to new batteries during installation is crucial for ensuring that the components function properly and remain in place under various conditions. Pressing down or using a hand roller effectively distributes the adhesive evenly and ensures a strong bond between the adhesive and the battery surface. This method allows for better adhesion, minimizing the risk of the battery moving due to vibrations or during operation.

Using a heavy object might exert uneven pressure on the adhesive, potentially leading to improper bonding or damaging the battery. Leaving the adhesive loose does not provide the necessary secure connection, which could lead to failure. Applying adhesive only to one side fails to create an adequate seal and bond, increasing the chances of the battery not functioning optimally.

Therefore, using a pressing action or a hand roller is the preferred method for ensuring that the adhesive properly secures the new batteries during installation.
