Questions about this item

What voltage does the 7.2V Ni-MH pack deliver to the TPI 440 oscilloscope?

The pack supplies a nominal 7.2V, matching the original specification for the 440 1MHz single-channel oscilloscope.

Will the 86.75 x 51.8 x 14.55mm case fit the battery compartment of a TPI 440?

Yes, the dimensions match the original 6P600A and A004 packs, so it slides into the same compartment without modification.

How do I install the replacement pack, and what step is often missed?

Power off the scope, open the battery door, disconnect the old pack, connect the new one observing polarity, close the door, then charge fully before first use — skipping the initial full charge is the common mistake.
