10. Make the battery down once a month. I know this is controversial. Yes, it was certainly true that the larger batteries had
"Memory effect" problem, but it was felt that the news did not. I guess we were wrong, because even Apple recommends draining your battery once a month. In fact, I'm draining my battery as I write this post. Not only that I ignored all the advice here (and unless you use the DVD player). It still took almost two hours drive from the machine until it is down to the reserve force. The next step is to drop asleep at any machine and run the battery completely down then recharge it again.
