Installing batteries in your Vansky VS-FL03-V 51- UV Light Flashlight is straightforward. First, make sure you have all the parts: the flashlight itself, the battery holder, and the back cover. Remember, the AA batteries are not included. Next, take the AA batteries and insert them into the battery holder, making sure the negative (-) end of each battery goes towards the spring inside the holder. Put the batteries in one after the other, paying close attention to the positive and negative directions. Once the batteries are in the holder correctly, put the holder into the battery compartment of the flashlight, following the direction indicated by the arrow on the holder; the arrow should point inside the flashlight. Finally, secure the back cover by tightening it onto the flashlight. This completes the battery installation. For visual aids and more details, consult the user manual that came with your Vansky flashlight.
