Difference between BR2325 and CR2325

[Winston Smith]

Can anyone tell me the practical difference between a Lithium coin
cell with the prefix "BR" and one with the prefix "CR"?

I see that the Panasonic BR2325 is an LiCF (Lithium
Carbon-monoflouride) and the Renata CR2325 is an LiMnO2 (Lithium
Manganese-dioxide)but what is the practical difference between the two
chemistries?

Thanks in advance,

Winston

What you need is the PowerStream primary lithium battery tutorial :-)

Thanks for the link (although it is more of a table with some Lithium
batteries on it, rather than a tutorial or primer). The bottom of the
page said things like "Choosing a Lithium battery", Lithium Cell FAQ,
etc, but there wasn't actually any links to that information.

The only information I could get from the table was that the 'BR' coin
cells only produce 0.03mA of current (!) (compared to 0.1-0.2mA for
the 'CR') and the difference in heat tolerance.

Are these the only differences?

The primer also mentions that BR types use fluorinated carbon chemistry,
while CR types use manganese dioxide chemistry.
Perhaps you missed seeing that.

Err... perhaps you missed this(from my original post):

Yep. I missed that. Sorry :(
I took your second post as if it stood alone.

Go to the home page and look to the left.

Click on technical resources.

Check http://www.mouser.com/catalog/615/978.pdf go to "Power" and then "Batteries".
You will find a catalogue (with specs) of preaty much all manufacturers making
prizmatic cells. Looking at the data of similarly sized BR and CR you can
see that carbon flouride cells have typically less capacity then manganese-dioxide.

CR2325 can deliver more current so may be suitable for more power hungry devices, where BR2325 cannot handle the load. So devices requiring CR2325 cannot use BR2325, however devices where BR2325 is recommended may use either.
