Energizer CR2025 3 volt lithium

These little batteries revived my kitchen scale in seconds, and the two-year shelf life means I can keep a spare set ready for the TV remote without worrying about them dying early.

Got tired of my car key fob dying at the worst times, so I swapped in a pack of these. They've been holding a steady charge for months now, and the consistent voltage makes a real difference in how responsive the buttons feel.

My garage door remote was acting flaky until I swapped in one of these, and now it works perfectly again. The ten-year shelf life is a huge plus since I always seem to need a battery at the worst time.
