Energizer MAX C型電池（4入），C型鹼性電池

The ten-year shelf life is the main reason I grabbed these, and it’s a relief knowing they’ll still work when the flashlight finally gets pulled out. They’ve powered our kid’s toy for weeks without a drop-off.

Stashed a pack in the emergency drawer and forgot about them for over two years; pulled them out yesterday and the flashlight lit up bright as new. the 10-year storage guarantee is the real deal for peace of mind.

Put these in my portable radio and they've been running strong for weeks. The 10-year shelf life is a nice bonus since I always keep spares in the drawer.
