What is the proper way to wall mount my Stanley Battery Charger?

Locate the charger within reach of an electrical outlet and away from corners or obstructions that may impede air flow. Use the back of the charger as a template and mount securely using drywall screws at least 25.4 mm long with a screw head diameter of 7–9 mm, leaving approximately 5.5 mm exposed. Align the slots on the charger's back with the screws and fully engage them. (Page 9)
