Actually, you should likely take what *Motorola* (and anybody else's user's
manuals, so as not to look like I'm picking on Mot) with a grain a salt;
it wouldn't be the first time that the information distributed in user's
guides, etc., was less than completely technically accurate. Or are you
saying that Motorola had one of their battery engineers write the manual?
I've already posted my complete explanation behind my comments - with
references, so I'm assuming 'nuff said. Right?
