Suits owners of compatible Dog Watch systems

Buyers with Dog Watch R-200 or R-100 collars needing a direct voltage and capacity match can use this cell. Those whose devices require a different voltage, capacity or physical footprint should look at other options.

7.5V 160mAh alkaline specification

The single specification that decides fit is the 7.5V 160mAh alkaline chemistry in the stated 27.8 x 12.4 x 12.4mm form factor. Match these values and the A175 or ST0214 part number to the collar's requirements before ordering.

Questions about this item

How do I install the Estry R-200 battery in my Dog Watch device?

Match the 7.5V 160mAh pack to the R-200 or R-100 compartment, align the polarity markings, and press the 27.8 x 12.4 mm unit firmly until it clicks; the step users miss is verifying the A175 or ST0214 part number on the old cell before fitting the new one.

What maintenance or replacement will the Estry R-200 battery need later?

The alkaline chemistry pack carries a 1-year service rating; after roughly twelve months of normal use the 1.2 Wh capacity will fade and the 35.0 g cell should be swapped for a fresh R-200 unit.

What limit appears first when the Estry R-200 battery runs under continuous load?

The 160 mAh capacity at 7.5V is the first ceiling; sustained draw will deplete the 1.2 Wh reserve quickly, triggering the built-in over-discharge protection before any thermal limit is reached.
