Direct replacement for Welch Allyn devices

This lithium-ion battery replaces Welch Allyn part number 72420 and fits models 14001, 14010, 14011, 14021 and 14031. It is built to match the original equipment specifications for clinical vision-screening instruments. The black casing measures 71.70 by 37.70 by 20.40 millimetres and weighs 100 grams.

Voltage and capacity define compatibility

The cell delivers 7.4 volts and 2600 milliampere-hours, yielding 19.24 watt-hours of energy. That exact voltage and capacity combination is the single figure that decides whether the pack will power your SureSight unit correctly. Using a different rating risks inaccurate readings or device shutdown.

Steady output during extended screening sessions

Under continuous use the chemistry maintains a stable discharge curve rather than a brief peak, so the instrument stays powered through long examination queues. The 2.6 ampere-hour rating supports repeated measurements without the voltage sag that can interrupt a test sequence.

Questions about this item

How long will the 2.6 Ah capacity run a Welch-Allyn SureSight device in practice?

The 2600 mAh pack stores 19.24 Wh, so run time depends on the device’s actual current draw; typical SureSight units draw well under 1 A, giving several hours per charge.

What connection does the battery use and what voltage does it deliver?

It is a direct-replacement Li-ion cell rated at 7.4 V with the original Welch-Allyn connector, so it fits the 72420 slot without adapters.

Will the 71.70 x 37.70 x 20.40 mm case fit the SureSight 14010 battery compartment?

Yes, those are the exact dimensions of the OEM 72420 pack, so it slides into the 14001, 14011, 14021, 14031 and 14010 models without modification.
