The energizer has much more mah than the rechargeable one I believe, can't find the exact number. I put the info of rechargeable one here is to provide a choice.

I would still use these over a rechargeable ones for things like my outdoor lock. Lithium Ions croak in the cold, and they will still lose energy over time faster than the Energizers.
RFD is not just about saving money, it's about the thrill of the hunt and getting the stuff I want without paying full price like Joe Shmoe did.
This applies to everyday items as well as high end items that I don't really need.

About 750mAh.

EBLs are garbage though, they're almost certainly a fraction of 600mAh.

Yup. Even low self discharge rechargeable batteries would be a bad fit to replace what most 9V's go into. For smoke detectors, thermocouples, multimeters, etc... that draw next to no power and just sit around, a non-rechargable lithium is ideal, and will probably give you a solid 5+ years of occasional use(obviously you're supposed to change your smoke detectors more frequently than that.... but if you didnt, you'd probably still be fine for a few years). With an eneloop, you'd prob. still want to take it out and recharge it every 2 years.

These would probably last around about 10years in a smoke detector.

ITT people who don't know what Lithium batteries are for. These are not rechargeable, nor would you use this in the same place you would a rechargeable.

Think extreme temps or extreme long life-low drain applications where a NiMh or Lion battery would be dead 100x over from self-discharge.
