Energizer CR2450 3 volt lithium

These hold a charge perfectly in my garage door opener's backup receiver, and they've already lasted longer than the generic ones I tried before. The 3 volt lithium chemistry seems to give them a much better shelf life too.

Popped one into my kitchen scale that had been dead for months, and it’s back to working perfectly. The 3-volt lithium power seems to last a lot longer than the cheap ones I’ve tried before.

These fit perfectly in my car key fob and lasted over a year with daily use, which is way better than the generic ones I've tried. The consistent voltage output has never given me any issues with the remote either.
