That information is totally bogus.
Here is a good guide. Maximum Battery Life - BlackBerryFAQ
A simple rule of thumb is when you get your BB, charge it to 100%. You can't do more than 100%, even if you leave it there 24 hours.
Afterwards, top it off whenever you like, in the car, at work, etc. Ten minutes here and there are good for batteries and your charge.
Charging does not affect your OS.
