The Welch Allyn Lithium-Ion Handle (Power Source) features "smart" lithium ion battery technology. The Welch Allyn Lithium-Ion Power Handle will power any 3.5v instrument head for 110 minutes... Twice as long as standard handles. The 71930 Lithium battery will not develop memory, which is a common problem with Nickle-Cadmium batteries. Welch Allyn employs CYCOLOY plastic resin in the construction and design of the 71930 Lithium-Ion Handle, making it more lightweight and comfortable for any sized hand. The Welch Allyn Lithium-Ion Handle offers special features such as the Soft Grip Rheostat for light-intensity control and Low-Battery Indicatior Light.
