English (West Midlands): of uncertain origin; possibly a nickname for an unruly child, or somebody who behaved like one, though this sense of brat is not recorded by OED before the 16th century. Alternatively, it may be derived from the older word brat(te) âapronâ, âpinaforeâ (of Celtic origin), as a nickname for someone who habitually wore one.

My MacBook Pro 13 is now 15 months old and has completed 318 cycles, according to Coconut Battery and my system info. I timed it the other day, with normal use (writing docs, email and the occasional Internet surf) and in 2.5 hours it went from fully charged to turning itself off when the battery ran out of charge.he concept of cycles is explained here: http://www.apple.com/batteries/. Apple says a battery should retain 80 percent of it health (not charge) after 300 cycles. The batteries in my Late 2007 MBP have not been so gracious.
