Replacement Battery for Digisat Meters

The Estry 8.4V 700mAh Ni-MH pack replaces the original battery in Acutrac Digisat Pro 22, Pro 22Pro MKII, Digisat 3 Pro MKII and Digiair signal meters. It matches the factory voltage and capacity so the meter powers on and runs exactly as designed. Confirm the PO201003 or NB-1X7 part number before ordering.

Thermals Noise and Power Draw

Nickel-metal-hydride chemistry delivers steady output without the heat spikes seen in some other packs during extended field use. The meter draws only the current it needs, so the battery runs cool and silent while powering the display and RF front end. Overcharge, over-discharge and short-circuit protection circuits keep operation safe.

Upgrade From Worn or Dead Packs

Swap this in when the original cell no longer holds a charge or shows reduced run-time on site. The 5.88 Wh capacity restores full-day operation for installers aligning satellite dishes. It is not for users needing higher capacity than 700mAh or a different voltage platform.

Questions about this item

How do I install this battery in my Digisat Pro 22 and what step is often missed?

Power off the meter, open the battery compartment, align the 72.1 x 45.4 x 10.5 mm pack with the contacts, and secure the latch; the step often missed is confirming the 8.4 V label matches the meter's requirement before closing the cover.

What maintenance or replacement will this Ni-MH pack need later?

Recharge after each use to avoid deep discharge; if runtime falls noticeably, replace with another 700 mAh 8.4 V pack — the built-in protection circuit guards against overcharge, over-discharge and short circuits.

What limit appears first during sustained field use of this 5.88 Wh battery?

The 700 mAh capacity sets the runtime ceiling; under continuous load the meter will shut down when the pack reaches its discharge cutoff, so carry a spare for all-day jobs.
