I would recommend these. The MK61 is much better in that regard. I just got one from the Ukraine and standard Energizer alkaline batteries fit in perfectly with no strain on the case whatsoever. If you're worried about your case, put in AAA batteries and if they're not long enough, fill the gap between the end of the battery and the terminal with wadded up aluminum foil (unless you're in a British English speaking country in which case you'd use aluminium!) The foil trick works in a pinch when you have no AA batteries but do have AAA's. Of course you'll get a bit less runtime but the drain on a calculator is small, other than from the florescent display. Tom L Cui bono? |
