MAC Laptop: Is it true if...

Is it true if you let out all the battery life every month and then recharge it it will extend the Mac's battery?

Anything with batteries (i.e. lithium batteries) will benefit from this.
It lets it die, and then build it's way back up.
You should do it monthly

No! As much as apple and Steve want to pretend they invented the wheel? They did not.

They use Li-Ion batts. If you want to know more than you ever wanted to know about Li-Ion batts keep posting. You know, say 300 to 500 charge cycles?
I really don't know. I learned myself that batteries have like X amount of times they can be charged. And also they will eventually decay in how long the battery can last.

My friend said the MAC Pros told him that if he does that, it will prolong how fast the battery life will decay. So if you don't do it, you might die from 2 hours to 1 hours quicker than doing it.

I just wanted to know.
You are talking either "memory effect" or something similar. Go read at, batteryU"!

Get back to us.

Li-Ion do not suffer from. I don't want to explain. Just use Google!
I hate to say this, but what should I google?

So theywon't wear off? so confused now lol
I have to say the batteries in Macbooks last a while if treated right.. I've cycled this one um... 338 times. It's still rated at 75% health. I usually get 3-4 hours out of it on the standard battery settings after having this laptop for over 2 years. (bought it in sept 06)

Just treat it right and it'll be good to you. This goes for any battery. (or electronics for that matter)

Li-Ion batteries? Battery university? Come on!

Edit they will wear! Get used to it!

Is there any other misconceptions you heard about Mac's?


It's best to recalibrate your battery once a month if you use your battery often. This also maximizes the lifespan and performance of your battery.

Note: This applies to not just Mac batteries but every lithium-ion battery pack.

Yes. It always helps to drain the battery all the way (Or at least very low) before recharging. Extends your battery's life tenfold.

Thanks, that's the answer I wanted.

Sorry, on the slow side. I'm stressing out on my Stat homework...this is why you should never sleep in class.(couldn't help it, lack of sleep)

No it does not rocket man, consider learning before posting. You could not be more wrong. Sorry!

Edit: It is worse on a Li-Ion it is a bad idea bro?

If hes wrong then prove it.

This is not true the only battery technology that you need to discharge before charging, to maintain its battery life are ni-cad batteries Nimh/Lipoly/LiION you do not have to

Exactly correct. Ni-cad are memory batteries so they need to be discharged every time.

Nimh, li-po and li-ion do not have to be discharged to fully charge.

Prove it how? You guys missed the term "memory effect"? That is the whole entire you don't have to run down to no charge before recharging? I mean what do you mean "prove it"?

Come down...
Thanks for helping...it would be nice to get some external sources.

And I'm not really questioning about the discharging.

Does discharging the battery then recharging afterward help the performance or not?

My friend said he was taught by "pros" that if he does that once a month, instead of quickly losing lets say 2hours to liek 1 hour, it would not make it to 1 hour that fast.
edit
Give me some time to read that battery U thing.

yes lets insult apple since they are the only company who says things like this...

but yes it will help the battery also. go to system info or whatever its called it will give down to the exact amount of charge the battery will hold and the cycle count!

First off the advice won't apply to most Macbooks produced within the last few years, as these Macbooks use Li-Ion batteries which do not have "memory". That means there is no need to charge and discharge them every so often (unlike Ni-Cad and Ni-MH batteries).

If you happen to have a older Macbook, then they mostly likely used Ni-MH batteries (Nickel Metal-Hydride) which do have the memory effect. In which case, discharge the battery fully every 2-4 weeks or so (frequency depends on how often you go from battery to charge and back-and-forth).

As for charging cycles, every battery has a finite number of charges/discharges. Li-Ions typically have anywhere from 500 to 1000+. That translates to about 3 to 8 years worth for the average user.

A lithium-ion battery provides 300-500 discharge/charge cycles. The battery prefers a partial rather than a full discharge. Frequent full discharges should be avoided when possible. Instead, charge the battery more often or use a larger battery. There is no concern of memory when applying unscheduled charges.
Also a short Wiki article on Li-Ion batteries.

Of course, there have been improvements to the battery's life cycles. I believe 1000 is the average upper limit nowadays.

Then again, that new Apple Macbook promises 1000+ cycles (think they said 2000 cycles in the T.V. commercial). Guess time will tell.
