    Li Batteries have a short life

    • Written by from Hudson

    My battery stopped functioning properly after two years. I see a lot of people having problems after one year. Unfortunately this issue isn't unique to Apple products. I've been in the PC support industry for over ten years. I mostly support other brands. A year to two is about what you are going to get from a laptop battery. You may be able to extend that life a bit by performing the proper maintenance on the battery. Before you get upset with Apple for the horrible battery life, look around. You'll see the same complaints on every other manufacturer's forums. It's the nature of today's batteries.

    Long Life Battery, If We Don't Abuse It

    • Written by from Stamford

    I purchased this battery like a month ago. The Apple Store Sales & Customers Service, gave me some very good few tips not to abuse the battery, "Do not overnight charge the battery" So it would give a long battery life. If it's getting hot, we will have to purchase protective case and a fan to avoid always getting hot and make sure, we gotta have a time limit to use our laptop.So we can avoid those problems. Those are sold separately and optional. But it is absolutely worth them to buy for the benefit of our laptop.

    I hope this is a helpful tips.

    4th battery in 4 years

    I've had 4 of these batteries in the 4 years that I've had the laptop. That is far too often.

    nothing new to add...

    • Written by from Seattle

    I got better quality life over its relatively short lifespan by power cycling. The first 200 cycles I got fairly decent length of time in-between charges (2+ hours). But streaming or any video-intense apps tend to heat things up, even when I put the laptop on a cool surface. This seems to accelerate the deterioration, which was fast this time around.

    Time to get a new one.

    Thought of the day: think if car batteries were held to the same industrial standards...

    Really Really Bad

    • Written by from Grand Rapids

    This battery is unacceptable by any standard, especially Apple's. My wife's (older) Macbook has just as many cycles on it and her battery still lasts at least 2 hours on a charge. I would be luckily if I got 15 minutes. I essentially have to keep my computer plugged in if I ever actually want to use it. Needless to say, I would not buy a new one. Looking at 3rd party options now.

    15" MBP Battery can't make up its mind

    • Written by from Warner Robins

    My MBP battery is at 227 cycles and does (now) still charge to 97% . It did NOT used to do this. It started showing "service battery" AFTER i started cycling it every few weeks per my owners manual and the 40 minute run time was making it about useless as a laptop, HOWEVER since i started using it at home in "clamshell" on my TV, leaving it plugged in all the time and being very careful what’s running when using it on battery it seems to have "fixed" itself. Since i've started leaving it plugged in clamshelled and having it start itself, i never have to open it or touch it so long as it's at home. The battery is now charged to 97% the status page in profiler says charged & "not charging" status is "normal" (note it used to say "service battery") and on the odd occasion i use it as a laptop it seems to go for between 3 & 4 hours? What happened? I have the "usual" dim charger light as well as all the other symptoms everyone seems to complain about, then why is my battery lasting so much longer? To start with delete FLASH, evaluate all non apple apps and look closely at what you have running in the background. then please read the thoughts-on-flash posted by Mr. Jobs. perhaps some of the issues MIGHT be mitigated if people would be more conscious of the processor usage, hard drive status and display brightness.For me anyway turning off/ sleeping unused resources. WiFI & Bluetooth appeared to make a tremendous difference. So much so, that I am no longer considering replacing my battery at 227 cycles especially considering the fact that now it shows as "normal". I can't fully explain it but i'm not one to complain about a happy mystery either. I hope this helps.

    DO NOT Completely Discharge Li-ion batteries

    • Written by from Boynton Beach

    If you want the facts on maintaining a lithium ion battery, simply google "lithium battery best practice". These batteries do not have a memory effect and one of the worst things you can do is to completely discharge them. Keep them topped off. And with any battery, you will only get so many discharge/recharge cycles. Also, never freeze them as this will damage the cells.

    Very disappointed.

    • Written by from Glencoe

    Gives you an hour and a half of internet time when brand new. Within 6 months, the battery wont even last an hour when fully charged, even when properly cycled.

    Short-Lived Battery

    • Written by from WILMETTE

    I am on my fourth battery in four years. Fortunately three of those batteries were covered by AppleCare.

    Although I often use the notebook with the power adapter plugged in, I do drain the battery at least once a month as recommended by Apple to maintain a healthy battery. What happened most recently is the battery drained completely and now fails to accept a charge. My overall experience is that this battery design and/or the charging system is rubbish.

    I've found that I can get the battery cheaper by going to the Genius Bar in an Apple Store. This saved me about 30%.

    Disappointed in Apple.

    • Written by from Moorhead

    I hold apple in the highest regard and promote their products passionately like they are of my own making. But I have to vent about the battery in my old trusty Mac Book Pro that has failed me for the third time. With the newest replacement battery that brings me in the ball park of $400.00 in battery costs with shipping. I have since bought a new Thunderbolt Mac Book Pro which ROCKS!. It is my hope that I am not writing the same disappointing story about my experience with my new purchase.

    It is ok to go back to R&D and demand they make a revision that lasts for your dedicated customers.

    Battery Life

    • Written by from MERIDEN

    After almost 5 years, I finally need a new battery. INCREDIBLE! This is why I will only own a MAC. Thanks for putting out a great product!

    After 5 years I finally need a new battery. Very impressed with the overall battery life on my mac. For those who have had battery failures so soon are more than likely using there battery wrong. You SHOULDN'T ever run your computer while it is plugged into AC power while the battery is in the computer. This will kill a battery in no time. Take the battery out and charge it after you shut the computer down. It will still run on AC power with no battery in.

    You people need to learn how to take better care of your Mac's...

    • Written by from Birmingham

    I have had my Macbook Pro now for 5 years. Have never had a problem with it until this month. My battery is going dead and needs to be replace. I would have to say that after 5 years all i need to do is replace a battery!!! Not a big deal. I'm surprised the battery has lasted this long actually :D I'm very happy with my Mac...

    Bad battery life

    • Written by from Stuttgart

    On my way to the third battery, too. After all that claims and angry people about the battery life in this MacBook Pro, why does nobody cares about? I wanted to stay with that Mac cause it still has the better Nvidia graphic board + is completely in Alu look. Return to the Nvidias and manufacture next generation MacBook Pros with a complete silver look will convince me immediately to buy my new Mac.

    Terrible quality control and durability

    • Written by from Los Angeles

    This is the 3rd time I'm ordering a new one of these. All the other ones stopped charging in a matter of months, with very little use (when using plugged in, I would remove the battery, which would run at slow CPU speed, but at least save the ultra-picky battery.)

    I went to the Apple store to complain about a possible logic board controller or charger problem, since my battery issues have been way too recurring. Nop, it's the battery again! This is the most overpriced, overrated battery in the market today. And all MacBook Pro users are stuck with it!

    WHen you know the general quality of our mac's, it is impossible to understand why these battery do not work properly. they have a very short life time. The last I bought last only few month.
    What is the position of apple to support its customers ???
    What is the status of the new macbook pro battery ???
