Welch Allyn's innovative next generation Lithium-Ion Handle (Power Source) features "smart" lithium ion battery technology. The Welch Allyn Lithium-Ion Power Handle powers any 3.5v instrument head for 110 minutes which is twice as long as a conventional handle. Lithium battery will not develop memory as is common with Nickle-Cadmium batteries. Welch Allyn employs CYCOLOY plastic resin in the construction and design of the Lithium-Ion Handle, making it more lightweight and comfortable for any hand. Additional features of the Welch Allyn Lithium Handle include: A soft grip rheostat for light-intensity control and Low-Battery Indicatior Light.
The power, versatility, and stamina of the Lithium-Ion Handle compliments the Welch Allyn 11810 or 11820 PanOptic
The Welch Allyn 71900 Smart Handle Power Source is supplied with a Pull-out A.C. Charging Module for wall plug recharging (pictured above). Please also see the Welch Allyn 71930 Smart Handle Power Source with Well Charge Adapter.
