I have used alkalines in my woodstock (and spice) series units with no ill effects. At the suggestion of someone here, i use used batteries that test nearer to the 1.25v of a fully charged ni-cad than the 1.5v of a new alkaline. I don't know if that is necessary but it can't hurt.

I have used alkalines in my Woodstocks during 6 years and disposable Lithium AA batteries since the 3 last years without any problems.
Typical use: 1 different calc every day during the whole working day.
