Replacement Battery for Connex ProBP 3400

This 2200mAh lithium cell matches the original specifications for the Connex ProBP 3400 and Pro BP s models. It replaces part numbers BATT11 and 6911 with a 3.7V, 8.14Wh pack. The single battery weighs 76.0g and measures 70.63 x 19.6 x 19.6mm.

Certified Safety and Normal Operation

The pack carries ISO9001, RoHS, CE, UN38.3 and MSDS certifications. Built-in protection guards against overcharge, over-discharge, over-voltage and short circuits during everyday use. Normal operation stays within the rated 3.7V output without excess heat or noise.

Sustained Load Behaviour

Under continuous draw the protection circuit maintains stable voltage until the 2200mAh capacity is depleted. The safety limits prevent thermal runaway during prolonged high-current discharge. The cell is not suited for devices requiring higher capacity or a different voltage.

Questions about this item

How do I install the Estry 2200mAh 3.7V battery into my Connex ProBP 3400, and what step is often missed?

Power off the device, open the battery compartment, align the connector pins with the socket, press firmly until seated, then close the cover; the step often missed is verifying the connector clicks fully into place before reassembling.

What maintenance or replacement will the Estry 2200mAh 3.7V lithium battery need later?

No routine maintenance is required; replace the pack when run-time drops noticeably or the battery no longer holds a full 2200mAh charge after normal cycling.

What limit appears first during sustained use of the Estry 2200mAh 3.7V battery?

The 2200mAh capacity sets the runtime ceiling; under continuous load the pack will reach its 8.14Wh energy limit and require recharging before further use.
