"it still does a lot of damage to have the charger plugged in all day. "
That was true years ago and if you believe this, then you should not buy any model you believe this to happen.
Battery management has come a long way since this was true but if you find a consumer that believes this then you try to bring them up to speed and if they can't accept it they you tell them to get units that have user removable batteries.
My question about a macbook battery. This macbook (2011) is the only computer/mac that is available for me to use at the moment and it will probably be that way for a while. My question is since i have it on all day, I don't want to have to replace the battery after 6 months of use or anything like that. I know some tricks to lower the battery consumption and all but still from my experience it still does a lot of damage to have the charger plugged in all day. The battery is working fine and all as of right now. i'm getting a good 6 - 8 hours using the macbook for going online to talk to friends, clients and searching the web. My question to everyone is how can I preserve this battery as long as I can? I have tried (on an older laptop)letting the battery almost run out of power before I charge the battery but that still seem to kill the battery life quickly. Is there any other way to perserve the battery on this Macbook? Any suggestions is appreciated.
