RE-chargable?






I don't know for sure, but looking at their Lithium rechargable battery page, these particular ones don't seem to be on there, although those all seem to be coin cell batteries.

As a rule of thumb i'd say that 3.7 volt lithium cells are mostly rechargable, and 3.0 volt cells are not. I'm sure some exceptions to that exist, but it is something to go by at frist glance.
 
Thanks everyone I ordered one of these and according to a reviewer the magnetic on/off requires a constant on state drawing .034 current.

 
I was wondering what kind of new "project" you had in mind when asking about these tiny cells. :D
Thanks for sharing that video. I never gave it any thought that you had to manually turn on the laser every time, this will sure save time.
 
Li-Mn may be different from LI-MN

LI-MN are rechargeable, the second letter being lower case may have some denotation of the chemistry ??

Typically CR anything is meant to be non rechargeable.

Those say Lithium-Manganese Dioxide and those often have a long shelf life of 10 years plus and don't self discharge as fast as rechargeable that lose 2% or more per month, it may be in how they are made more than the chemistry and I have heard of people recharging NON rechargeable cells but it's not the way they were built to be used.

........Lithium batteries are typically disposable where as Lithium Ion are rechargeable..........

So primary batteries are chemically charged upon construction, where as accumulator batteries first have to be charged after their construction, so again it may be more of how they are constructed rather than what they are constructed of.

Now I have to figure it out LOL

EDIT: Ok Li-Mn stamped on the battery means Lithium Manganese Dioxide, so the Li just means lithium, not Lithium Ion.

The chemistry is actually Lithium-Manganese Dioxide in this case and not meant to be rechargeable, but the self discharge rate should be much slower.

Interesting thing is as cells slowly self discharge they build up tiny pathways, but a quick reverse spike while charging can break those pathways otherwise self discharge gets faster over time.
Something we all hated about NiCad and NiMH.

CR usually aren't rechargeable, but they are sometimes used to just refer to the size of the cell, such as CR123 and CR2, which are 16340 and 15270 sized. The CR prefix means non-rechargeable lithium-magnanese oxide chemistry, but is often confused (try find rechargable CR123 cells on ebay or something).

This confusion arises from rechargeable replacements for the original primary cells coming to market, and vendors want to stress compatibility with the original non-rechargable battery. CR123's are, for example, used in photo camera's and were pretty expensive, so getting rechargeable replacements made sense.

Downside is they are not that compatible as the cell voltage of a rechargable is about 1 volt higher which could damage equipment.
