Replacement battery for USM 36 ultrasonic flaw

This KingSener RRC2020 is a lithium-ion replacement battery built for the USM 36 ultrasonic flaw detector. It delivers 8850mAh capacity at 11.25V, matching the original 99.6Wh specification. The pack is supplied new and ready to install.

Who this suits and who should look elsewhere

Technicians maintaining a USM 36 flaw detector will find a direct fit with this pack. It also replaces the long list of part numbers shown in the compatibility data for Samsung, Philips, Getac and Cobham devices. Buyers needing a battery for any other instrument should look elsewhere.

Deciding specification: 11.25V and 8850mAh capacity

The critical figure is the 11.25V operating voltage combined with 8850mAh capacity. If the original equipment requires a different voltage or a significantly different capacity, this pack will not work. Verify those two numbers against the device label before ordering.

Questions about this item

Will the RRC2020 fit the battery bay of my Getac X500 without modification?

This pack replaces the original Getac X500 battery and matches the listed part numbers for that model, so it seats directly in the existing bay.

What is the correct orientation when inserting the RRC2020 into a Samsung P28, and what step do users often miss?

Align the gold contact strip with the connector inside the compartment, slide the pack in until the latch clicks, then lock the latch — skipping the lock leaves the battery loose.

How do I know when the 8850 mAh RRC2020 needs replacing in my Philips TC70?

When a full charge no longer powers the TC70 for its usual operating time, the cells have degraded and the pack should be swapped for a new RRC2020.
