Questions about this item

How do I install the Estry SRT-100 battery in my PDT20-10646 device, and what step is often missed?

Match the 7.2V 150mAh pack to the device contacts, insert it with the 35.8 x 26.0 x 15.5mm dimensions aligned, then secure the latch; the step often missed is confirming the 57.2g pack seats fully before closing the cover.

What maintenance or replacement will the Estry SRT-100 Ni-MH battery need later?

Expect to replace the 150mAh pack after roughly one year or when run-time drops below 1.08Wh; no scheduled maintenance is required beyond avoiding deep discharge and storing at room temperature.

What limit appears first during sustained use of the 7.2V 150mAh Estry SRT-100?

The 1.08Wh capacity is the first limit; under continuous load the pack delivers about 150mAh before voltage drops and the device shuts down.
