Replacement battery for Welch-Allyn handles

This 3.6V Ni-Cd rechargeable pack replaces part numbers 72200 and 78904586. It fits Welch-Allyn ophthalmoscope and otoscope handles including models 11720, 11730, 18100, 20000, 21700, 71000, 71003, 71010, 71015, 71020, 71022, 71050, 71051, 71054, 71055, 71110, 71150, 71610, 71670, 72200, 72207, 74710 and 97210. The battery is supplied new and ready for installation.

Capacity and runtime

Rated at 750mAh and 2.70Wh, the pack delivers a nominal 3.6V output with a 3.5V reference point. It powers compatible handles through routine clinical examinations and standard duty cycles. Runtime will diminish as the Ni-Cd chemistry ages or if the device draws higher peak current than the cell can sustain.

Upgrade from depleted original cells

The pack directly replaces exhausted factory batteries in the listed handles, restoring full portable operation without tool modification. The jump is worth it when the original cell no longer holds sufficient charge for a full session or shows voltage sag under load. It is not suitable for handles that require a different voltage, chemistry or form factor.

Questions about this item

Will the 3.6V 750mAh Ni-Cd pack power my Welch-Allyn 11720 otoscope handle the same way the original 72200 battery did?

Yes, this 3.6V (3.5V) 750mAh 2.70Wh Ni-Cd pack replaces part numbers 72200 and 78904586 and is listed as compatible with the 11720 handle among many other Welch-Allyn models.

How can I confirm the battery is working correctly after installing it in a 71050 handle?

After a full charge the handle should deliver normal illumination intensity and run time; the pack is rated at 3.6V (3.5V) 750mAh 2.70Wh, so performance should match the original 72200 specification.

What comes in the box and do I need a separate charger for the 2.70Wh Ni-Cd pack?

The package contains the 3.6V 750mAh Ni-Cd battery pack only; it recharges inside the compatible Welch-Allyn handle (e.g., 71010, 71150, 72207) using the handle’s existing charging base, so no extra charger is required.
