  • 7 V nominal voltage provides 8.14 Wh energy

Compatible Replacement Battery

This lithium-ion battery replaces the original power pack in Welch-Allyn Connex ProBP 3400 and Pro BP devices as well as Riester L otoscopes, laryngoscopes and ophthalmoscopes. It matches part numbers 6911, BATT11 and 10691 so clinicians can swap cells without tools.

Voltage and Capacity Limits

The cell delivers 3.7 V and 2200 mAh for an 8.14 Wh rating, which is fixed by the chemistry and cannot be increased by the charger. Runtime will vary with the instrument's current draw, so expect shorter cycles on high-brightness otoscopes or continuous laryngoscope use.

Check Connector and Dimensions

Verify that your device accepts a 70.63 mm by 19.60 mm by 19.60 mm pack with the original two-pin layout before ordering. Some Welch-Allyn revisions use a different keying, and the battery will not seat if the polarity tabs are reversed.

Questions about this item

Which capacity version should I choose for the Welch-Allyn Connex ProBP 3400?

This model provides 2.2 Ah at 3.7 V, delivering 8.14 Wh — the single capacity offered for this device.

What does the 8.14 Wh rating mean once the battery is installed in the monitor?

It indicates the total energy the pack can supply, determining how long the Connex ProBP 3400 can run between charges.

What interface does the DS-CS-WB340MD use and what does it limit in practice?

It connects via the proprietary Welch-Allyn battery interface, so it only fits the listed Connex ProBP 3400, Pro BP and Riester scopes.
