Playing the devil's advocate for our hypothetical legal department, 
shouldn't we only charge batteries that we have tested against and know 
the charging curve for, so that we know we won't overcharge and 
potentially cause the battery to explode? For this reason (I suspect) 
all cellphones look for the ID of the battery, and if it's not the one 
they were designed for, they refuse to charge.*

Granted, this is an extremely paranoid point of view, and is not mine. 
Besides, since our source is open, nothing prevents anyone from find the 
code that does that test, and bypassing it.

Assuming, of course, that this is the reason we do not charge BL-5C and 


* Another reason is that the cellphone maker would have you buy the 
expensive battery from them, rather than the cheaper knock-off 
replacement from Radio Shack or whatever.
