Cameron & Co DS-CS-WB220MD Welch-Allyn battery

This 7.4 V 3400 mAh lithium-ion cell replaces the original Welch-Allyn Connex Spot and Grason-Stadler pressure-unit packs. It delivers 25.16 Wh in a blue housing measuring 68.80 x 39.50 x 18.70 mm and is supplied as a single new unit.

Check device model and part number before ordering

Verify that your monitor or pressure unit lists part numbers 901000, BATT22, OM11878 or TM78370 in its service documentation. Confirm the battery bay accepts the stated dimensions and that the connector orientation matches the original pack. Ensure the equipment charges at 7.4 V so the cell voltage is correct.

Direct OEM replacement for Welch-Allyn packs

The cell substitutes factory batteries marked 901000 or BATT22 without modification. The upgrade is worthwhile when the original pack no longer holds sufficient charge for a full clinical shift or shows swelling. It is not suitable for devices that require a different voltage, capacity or form factor.

Questions about this item

Does the box contain only the 7.4V 3400mAh blue Li-ion battery or are cables or chargers also included?

The package contains one blue Li-ion battery rated at 7.4V 3400mAh. No cables, chargers or additional accessories are supplied.

How do I know whether the DS-CS-WB220MD is the correct version for my Welch-Allyn device?

This battery replaces part numbers 901000, BATT22, OM11878 and TM78370 and fits the Connex Spot, Connex Spot Monitor, Grason-Stadler and Pressure units. Match one of those codes or device names to confirm compatibility.

What does the 25.16Wh rating mean for actual runtime in a Connex Spot monitor?
