MacBook Power Usage in Sleep Mode

Mac Talk Forum: Digital Photography Review - forums.dpreview.com
Hi everyone,My wife has an old MacBook that were trying to "revive" with an SSD. I was considering a new battery as well, but I downloaded Coconut Battery and it said that she has 473 cycles and 83% battery capacity left. Those numbers don't mean much to me, but someone at the Apple Store told me that a laptop in sleep mode should lose about 1% of battery power every hour. Does that sounds right to everyone? I charged her MacBook fully yesterday and unplugged it around noon, and by the same time today, it was about 75%, so relatively close to the Apple Genius' gauge of a "good battery". Does the 1%/hr loss in sleep mode sound right to you?Thank you!
