Duracell Electronics LR44 アルカリ電池 2個入り

Used a pair in my kitchen scale after the old ones died mid-bake, and they’ve held steady for two months without a hiccup. The Duralock Power Preserve really does seem to keep them fresh, even in the drawer between uses.

These have been lasting noticeably longer in my child's toy than the previous generic brand I tried. The Duralock technology seems to make a real difference for keeping them fresh. Only minor gripe is the two-pack is a bit small for devices that need multiple batteries at once.
