How To Install AAA Batteries In Your Device

First identify the positive and negative ends of the battery. On a typical Alkaline AAA battery, the flat side will usually be the positive side. On the opposite side, a small circular protrusion should be visible. The side is typically the negative end. Now that you have determined the positive and negative ends of the battery, you can easily align it with corresponding markings on your device. Please note that some devices have small metallic tabs for battery retention and function. It is very important to leave these tabs unharassed and undamaged as doing so may compromise the performance of your device. If you do slightly move this tab out of place, they can usually be fixed by carefully readjusting them back into the proper orientation.
