I just did nearly the same (I removed 2 of the 4 batteries) with an HP-48GII (late, 4-AAA version) and it also still works. Not a surprise, since it's basically 49G+ h/w with a smaller LCD. Not sure about the earlier, 3-AAA 48GII as I believe it uses a different, non-compatible serial/USB cable, which is not handy.
