Difference Between Li-ion and Li-Mn?

[Robert S]

So i tried to find an answer to that because i wanted to buy some AW batteries, and on their website, they have protected Li-ion cells and unprotected Li-Mn cells.
The max capacity unprotected 18650s you can buy from them, are 2200 mAh and the max capacity for their protected ones is 3400 mAh.

Another site is selling the same unprotected cells with the same mAh as Li-ions, so whats the difference?

All i read was that Li-Mn is just a sub category of Li-ion, so it doesnt matter, its same voltage and uses the same charger.
But if its just all the same, aside from them beeing litium manganese, which just seems to be a different chemical composition, i find it a bit confusing, unless there is some advantage in using it.

Also, why the lower mAh? Are they just more efficient or something? Like you cant really compare the mAh of a Ni-MH battery to that of an Alkaline battery?

The difference is the anode material. Basically IMR is capable of higher current, but has less capacity. Using 10C/2C rule, that IMR should be okay for up to around 22A, while that standard li-ion should be okay for up to 7A.

Okay, thanks, thats something i understand, but i guess i dont need it, to run a laser, right?
I dont think, anything im doing with those batteries, will need so much current.
Flashlights and lasers are probably the only things im using these batteries in.

Yup, u dont need those li-mn battery. Li-ion is enough for a laser

Thanks for the answer, ill go for some higher capacity batteries, then.

They're (Li-Mn) also supposedly safer and can be cycled more.

Good to know, but i think the ones from efest, sanyo and so on will be more than enough for me, safety shouldnt be a problem either, i wont stick them into some cheap ultrafire charger or try to burn them (thats almost the same i guess).
