You could but if you're using alkaline cells how would you connect them up? There's not enough room in the battery compartment for springs, you can't/shouldn't solder to them, so you'd have to weld them together somehow. If you use AAA cells a 3 x AAA plastic battery holder will fit in the battery compartment very nicely and they're very easy to replace. Also, AAA alkaline cells have more capacity than the original AA nicad cells so the calculator will run for a longer time between battery replacements (or recharging as you could use AAA rechargeable cells too).

The OP didn't actually specify alkaline cells I was just assuming that.

Katie, What type of holder do you put your AAA alkaline cells in? I'm very interested in this approach.

Thanks!

Bob
