What do the letters CR stand for?

The "C" denotes a lithium-manganese dioxide chemistry.

The "R" means it's a round (cylindrical) cell.

Similarly, LR means alkaline round cell, FR means lithium-iron disulfide, HR means NiMH, and SR means zinc-silver oxide.

Ok so good news, why the hell change model name
Many manufacturers use their own naming schemes, unfortunately. Take a look at the packages for the various generic coin cell types, especially; they usually have a list of about a dozen manufacturer-specific model names that they're compatible with, which all mean the same thing.

Unfortunately (as usual) not everybody complies with the standards: LR91 for example is lithium, not alkaline. Voltage however is similar to alkaline, perhaps this is the reason.

Huh?

You mixed the two designations! You are mixing up the letters! You are mixing up the "L" and the "F".

I think you mean FR91 and L91. Both refer to Lithium AA.

No such thing as a "LR91" to mean Lithium.

:oops:

I think, you are right. Energizer themselves speak of L91.

But if you enter LR91 in Google, you find tons of lithium batteries. Why the ... ? Very confusing.

I typed LR91 on Google and I get a lot of aerospace, laser, model stuff, not lithium batteries.

Maybe Google is doing regional specific searhces. From where you are, when you type LR91, you get Lithium batteries. From where I am I get space techie stuff.

Even if I try to employ google.com I'm switched to http://www.google.de/ .

And when searching for lr91 there I get this:

Ergebnisse 1 - 10 von ungefähr 2.920 Seiten auf Deutsch und Englisch für lr91.

If I search for lr91 energizer this is the result:

Ergebnisse 1 - 10 von ungefähr 575 für lr91 energizer.

Even in CPF you find a few hits for LR91.

I'm conviced now that LR91 is wrong, but it seems to be widely used.

Re: Whats the diff between CR123 and 123

Yes, it is.
Often on CPF, we use the manufacurer's initials instead of the "CR" part to make it clear what battery we are using.
--> SF123 instead of Surefire CR123
--> Energizer 123 instead of Energizer CR123

Re: Whats the diff between CR123 and 123

They are all the same. Take a look at the CR123 page at Battery Junction.

Most of the 123 type batteries have a statement in their descriptions similar to this:

Replaces: 123, 123A, BR2/3A, CR123, CR123A, CR123R, CR17335, CR17345, DL123A, EL123AP, K123LA, L123A, SF123A, VL123A, 5018LC

No such thing as a "LR91" to mean Lithium.

Energizer L91 = FR6 in IEC

No such thing as FR91...
