The easiest way to insert batteries into a clip is by sliding them up from under the clip. There are some moulded stops designed for the proper alignment of the batteries in the clip. This ensures that the battery terminals make the proper contact when the compartment door is fastened to the unit. It is important to insert the batteries into the clip with alternating polarity. A fully loaded clip is shown below. As shown on this photo, the polarity of the batteries is positive, negative, positive, negative. You can easily slide the batteries up and into the clip. The battery clips are also marked with plus and minus signs to indicate the polarity of the batteries. If you use batteries without polarity markings, just remember that the flat end is negative and the end with the raised knob is positive. 6
