Replacement battery for PocketScope devices

This Estry 72801 is a 2.4 V 800 mAh Ni-Cd battery built to match the original specifications for Welch Allyn PocketScope ophthalmoscopes and compatible handles. It suits clinicians and biomedical technicians who need a direct replacement for part numbers such as 72801, 72600, 72830, 72837 or MED1025.

Check model and part number before ordering

Verify that your device lists one of the compatible model numbers (72801, 72600, 72800, 72830, 12800, 72837, 211, 22820) or battery part numbers (I-MED1025, CL50168, B11617, MED1025, AB24667, CL50158, MNC726, AMED1025, MED-72600). The pack measures 104.62 x 15.82 x 14.58 mm and weighs 91.5 g, so confirm the battery compartment can accept those dimensions.

Steady output during extended examinations

Rated at 1.92 Wh, the cell delivers a stable 2.4 V through long clinical sessions without the voltage sag seen in short-burst tests. Integrated protection guards against overcharge, over-discharge, over-voltage and short circuits, while ISO 9001, RoHS, CE, UN38.3 and MSDS certifications confirm consistent manufacturing quality.

Questions about this item

Does the Estry 72801 pack include a charger or only the 2.4V 800mAh Ni-Cd cell?

All the numbers shown — 72801, 72600, 72800, 72830, 72837, 211, 22820 and the I-MED1025 series — refer to the same 2.4V 800mAh Ni-Cd replacement; pick the one that matches the label on your original pack.

What does the 1.92Wh rating mean for runtime in a PocketScope ophthalmoscope?

At the rated 800mAh capacity the pack stores 1.92Wh; actual operating time depends on the instrument's current draw, which varies by model and brightness setting.
