    Hi guys. Let me know how to charge the replacement battery for Macbook pro. I see it came with 50% charging. Do i need to use it until sleep mode and then recharge or I can charge it from 50% to 100%? How many hours?
    Regards

    You can use it right away, if you wish. Yes, you can charge it right away. There's no need to drain it first. This should answer most, if not all, of your battery questions:

    That is absolutely unnecessary and wastes a cycle for no reason. Read the FAQ I just posted.

    Thanks! I've heard I need to charge until 100% and then wait more 2 or 3 hours with the a/c cable plugged. So I unplug it and drain until sleep mode. Is it necessary?
    Another question. Can I use it all the time plugged with battery on or once the battery is charged I need to umplug the A/C cable? I mean, when we calibrate Macbooks it shows how many cicles it had ..etc.. I was wondering if I use it all the time with the a/c pluged the cicles won't count. lol
    Let me know the best way to use it. My laptop is on 24hs almost.
    Regards

    That's part of the calibration process. Read the CALIBRATION section of the FAQ I posted.
    Read the FAQ. It directly answers your questions. The CHARGING and AC Power sections address your concerns.

    I read all the topics but it didn't say how to charge the battery for the first time. So I suppose its a normal charge , until 100%. Isnt it?

    Yes, it's addressed in the very first link in the FAQ: About Apple Notebook batteries

    After reading all these infos ,I see I can use the laptop for 2 or 3 days with A/C plugged and then take off and drain the battery at least until 50% and plug the a/c on again.. isnt it?
    I thought it would make my battery "addicted"(using most of time with a/c plugged) but no. They inform exactly the opposite way.
    Do I need to calibrate it once a week? I can also see , I can turn the laptop off and leave it with the a/c power plugged. Isnt it?

    My english is not that good ( Im brazilian) but I could understand the best way for your battery life is use the a/c power on your laptop as much as possible ( maximum 2 or 3 days directly) then take off the a/c and use the battery from 100% to 50% at least ( is it better if I use until 10% or sleep mode)?
    Thank you so much , GGJstudios!

    I mean, I understood what I can and what I can't do but I need to know the best way to use and extend the battery life and duration of my laptop.
    Are these infos all? Just need to use the laptop plugged and thats it? Calibrate once a month is ok? I've bought 2 new replacement batteries ( one for a white macbook 13" and the other for a Macbook Pro 15" methalic ,old version).
    Regards

    Just run on battery when you need to and run on AC power when you can. Just make sure you don't run on AC power all the time.
    No, once every month or two, as the FAQ says.
    Yes, that's fine.
    No, use it on battery AND use it plugged in. You need to run on battery some to keep it healthy. Don't run on battery ALL the time and don't run plugged in ALL the time. Change it up.
    Yes.

    Cool!! Do you think I can run 2 days on battery and a/c power plugged and then unplug a/c and run 50% of battery? Is it ok? As I told you , my laptop is on 20 hs/day so not sure if I can leave the a/c plugged as Apple informed. Do I run only 50% everytime I take off the a/c power or bit more?

    Thanks

    Yes, it's OK, and you don't have to run to exactly 50% when you run on battery. Just run it on battery for several hours. 30%, 75%, 40%... they're all OK.
