I can recommend lithium cells (the ~1,5 volt variety). They are marketed for use in high drain applications but their long shelf life and near-immunity against leakage makes them ideal in low drain or seldom used equipment. Only available in AA and AAA size though.

They have a slighter higher voltage and a flatter discharge curve than alkaline cells which often is a benefit. They are a bit hard on incandescent torches though.

Expensive, yes, but they last for years.
