Silver oxide cells (usually rated 1,55 V) have a significantly higher capacity than alkalines, so I would prefer these. Also their voltage drops much slower during use. Be sure to get fresh ones from a major manufacturer. A good source are photo stores: the S76 / SR44 was used in many classic cameras of the Seventies and Eighties. Since these batteries will power your calculators for many years I wouldn't care about one or two $/€ more or less.
