The invention relates to a battery comprising a casing having at least one handle, which is formed integrally with the casing and is at least partially recessed into the upper surface of the casing. The PTC compositions of the present invention exhibit improved processability and include at a minimum an organic polymner, a conductive filler and a low molecular weight polyethylene processing aid. The first message is transmitted by using a close-range, standard-protocol radio signal. All the descriptors may point to the same buffer in the external memory, which stores the multicast packet.
