Hi all,

I am about to drain the battery for the MBP, the health of the battery is rather low right now. What is the best way to do it to make sure the battery is drained entirely? (or should I not do that?)

Thanks!

Goyan

what about after the MBP's gone to sleep, there still will be a tidy bit of energy left in the battery..... should i get rid of those too? if so, any quick way of doing it?

Thanks again!

I hope you are not doing that every time you use the battery.

You may charge the battery in the MacBooks whenever you please, that batteries are stressed more when you drain them completely and charge them fully constantly.

I'm pretty sure if you leave it in sleep mode, unplugged, for more than 5 hours it will drain the battery all the way

type "yes" without quotes into a terminal window. Open up a few and do the same.

I assume you want to calibrate the battery, so here you go.

Run some CPU-intensive process. This can be everything from running the "yes" command in the Terminal, encoding a huge video. When the machine will go to sleep, let it sleep. It will take about 5 hours for it to completely drain its charge and shut down.

basically draining it till it sleeps from lack of power, yep. Then wait 5 hours without charging.

If you get rid of the last but of battery charge you may put the battery into what is called deep discharge which means either it will never be able to charge or it will take around 48 hours to start charging again. Both very very bad.
