I only remove batteries for older, non-replaceable calculators of great value and mainly used for display. If you're planning on using a calculator every few weeks or months, then leave the batteries in. Just make sure they're not Duracell. HP issued a special warning about Duracells years ago. I don't know if the newer ones are more leak-proof but why take a chance?

I didn't know about the problem with Durcells -- I have three AAA Duracells in one of my HP48GXs. Perhaps I should replace them with Energizers?
