So whats best for macbook pro battery's? i have a 13" mac book pro with the 10 hour battery life and i would love for it to stay like that but i know over time all batteries start to decrease in power. any ideas to keep my bettery life full and strong? i've heard to turn off your laptop everyday at least once a day. i've also heard turn it off once a week. and ive also heard to just let it run out of power then plug it in again to get a nice full charge and then wait till its completely empty to charge again with never really actually shutting down. So whats best?
