The original models can be distinguished by their elongated antenna base, white-translucent keys and gray keypad background. Accessories for the phone included car, desktop and overnight travel chargers, installed hands-free car kits, leather cases, and a selection of batteries. The slimmest battery then available was the Slim and Slim Extended (Life), followed by the Standard, XT, and Talk-Pak XT batteries. The Talk-Pak XT and XT used Nickel Metal-Hydride while the others used Nickel Cadmium. A Lithium Ion battery was introduced in 1994.
