It fits Welch-Allyn models including 11720, 11730, 18100, 18200, 20000, 21700, 71000, 71003, 71010, 71015, 71020, 71022, 71050, 71051, 71054, 71055, 71110, 71150, 71610, 71670, 72200, 72207, 74054, 74710 and 97210. Clinics and technicians restoring otoscope power will find the correct fit.

Voltage and Chemistry Must Match Device

The pack delivers 3.6 volts and 750mAh capacity using nickel-cadmium chemistry rated at 2.70Wh. Only a 3.6V Ni-Cd pack with the same connector layout will charge and discharge safely in the listed Welch-Allyn handles. Buyers needing lithium-ion or a different voltage cannot use this pack.

Simple Snap-In Install With Polarity Check

Installation requires opening the handle battery compartment and pressing the pack into the existing connector. The keyed plug prevents reversed insertion if aligned correctly. Common issues are forgetting to charge the new pack fully before first use and leaving the otoscope on the charger continuously, which shortens Ni-Cd service life.
