Replacement battery for AMC oscilloscopes

The Estry 8333 is a nickel-metal-hydride pack rated at 9.6 V and 3000 mAh. It matches the original dimensions of 134.62 x 67.42 x 17.6 mm and weighs 538.0 g. The pack is built as a direct drop-in for the listed AMC and OX oscilloscope models.

Thermal behaviour and power characteristics

Ni-MH chemistry runs cool during typical bench use and does not require active cooling. The pack includes over-charge, over-discharge, over-voltage and short-circuit protection circuits. Self-discharge is low enough to hold charge through intermittent measurement sessions.

What the certifications and bundle mean

The cell carries ISO 9001, RoHS, CE, UN 38.3 and MSDS approvals, confirming compliance with international safety and transport rules. No charger, cable or software is included in the single-pack package. Buyers needing a different voltage or a multi-pack kit should look elsewhere.

Questions about this item

How do I install the Estry 8333 battery in my oscilloscope, and which step is most often missed?

Power off the unit, open the battery compartment, disconnect the old pack, connect the new 9.6 V 3000 mAh Ni-MH pack observing the correct polarity, secure it in the 134.62 x 67.42 x 17.6 mm bay, then close the cover. The step most often missed is verifying the connector orientation before forcing it in.

What maintenance or replacement will the Estry 8333 Ni-MH pack need over time?

The 3000 mAh Ni-MH cells will gradually lose capacity; plan to replace the pack when runtime no longer meets your measurement sessions. No scheduled maintenance is required beyond keeping the contacts clean and storing the oscilloscope in a cool, dry place when not in use.

What is the first limit I will hit when running the Estry 8333 pack continuously in an AMC 8333 oscilloscope?

The 34.56 Wh energy rating sets the runtime ceiling; under sustained load the pack will deplete before any thermal or voltage-cutoff limit is reached, so the practical limit is the available capacity itself.
