[QUOTE="Chris2121, post: 603946, member: 48853"] On Tuesday I purchased a new revision MBP, to be used almost exclusively as a desktop replacement system (It most likely will remain untouched on my desk and plugged in to AC adapter 95% of the time). According to [URL="http://www.apple.com/batteries/notebooks.html"]this Apple site[/URL] under the "standard maintenance" heading, Apple claims that an ideal situation to prolong a battery's career would be a commuter who partially drains the battery on the way to work, and recharges it thereafter. If I unplugged my AC every day to simulate this scenario, that would give me roughly 365 cycles per year - hopefully leaving me with 80% of capacity after a year, as per Apple. Is this a good level to be at after a year? I'm not really very knowledgeable about laptops/batteries. Also, when apple says "80% after 300 full charge cycles", does "full charge cycle" imply a COMPLETE draining and recharge of the battery, or would it imply double 50% charges, for instance? (iStat counts any partial charge as a "cycle"). I still plan on doing a monthly calibration, but am wondering if I shouldn't just take the battery out altogether and store it at 50% or so charge.... My choices are: -Partially drain/recharge every day -Partially drain/recharge every other day, once per week, etc. -Remove battery @ 50% charge and store it for whenever I should (ever?) need it I know it seems silly to worry so much about a battery when I'll not be using it that often, but I'd like to avoid a replacement charge down the road if I can. Even if there's only once that I'll actually need the batt, if I can only get 40 minutes out of it, then it's useless. Any thoughts??...thanks for your help! [/QUOTE]
