    I have a macbook 2,1 from around June 2007 (so around 3.5 years old) and I've used this machine every day since I had it.

    The full capacity of the (original) battery is currently around 4788mA after 975 charging cycles, and I get around 4.5 hours of browsing and general use (I'd get around 5 hours when it was new). Programming I get 2-3 hours depending on what I'm doing.

    The key to keeping these batteries working for a long time is to fully discharge and recharge them often and not partially discharge and then leave them plugged in on the mains all the time.

  • Yes there is a difference between the two of them. It just has to do with they way the work and the life of the battery. However all you can get for the MacBook is the polymer battery. On mine I have had it over a year and I still get about 4 to 5 hours and I use it for internet and to take notes in college.

  • Mine is now completely dead (asking me to replace it) after 328 cycles, and almost three years' use. Mostly, I used my black MacBook while plugged in though, which explains the relatively low cycle count.

  • The first battery of my Macbook black died after 2 years. Got replaced by apple. The replacement died after 14 months with 71 (seventyone!) loading cycles. As Apple Care ran out last year, I had to buy a new one myself.

  • Li-Polymer is a newer formulation giving superior capacity compared to the same sized Li-Ion battery. Most if not all Apple batteries are now Li-Polymer.

    Neither battery should be run down completely except for Apple's recommendation of a once a month full discharge to calibrate the battery "gauge" in the menubar. Fully discharging the battery more than that will shorten its life significantly.

    Ideally, you would let the battery get down to 50% and then charge it, but that's not always possible.

    The second worse thing is to leave a notebook plugged in around the clock. For maximum battery life, shut the notebook off and unplug it from the charger.

    It's ok to leave the charger connected if the computer is in use. If you sleep the computer at night, you'll need to leave the charger connected.

    Battery life can very greatly among different users, depending on settings used and care of the battery. I got 4 hours of use after 2 years, but then it started going downhill fast.

    Your mileage will vary.

  • I was told some time ago that Li-Polymer and Li-Ion batteries don't need to be fully discharged before charging. I'd post some links confirming this but it seems Apple doesn't allow them!

    Personally, I've had my Macbook for 6 years and it's used every day. Sometimes plugged in and sometimes not. Nearly 400 cycles so far and still lasts at least 2 hours.

  • I purchased my white 13 inch laptop in 2008. Today 26/02/14 I had to change the battery for the first time. Not because it ran out of life but because it collapsed, which according to Apple store is the sign that the battery has worn out and needs replacing. The best way to maintain life in the battery is to fully discharge, then charge regularly. I am not expecting though that I will be so lucky with this new battery, so probably 2 years max it will need replacing again. Price of battery £109 so not cheap.

  • My MacBook Pro 13" Mid 2010 age is now 4 years 2 months, with 840 loadcycles. Currently it holds 5114 mAh from its original 5770 mAh design capacity, still holds 89% capacity. You're right dude, and I followed Apple's MacBook battery guide to keep the juice flowing with its Lithium-Polymer.

    I never plugged it in all the time. Always recharge when it goes around 20% to 100% and keep it running on. You may leave it plugged in all day but it should be awake, I use Caffeine for it. What I learned is if it plugged in too long while it's turned off or while sleeping, it will decrease the capacity. I don't understand why, but it is. Of course, might leave it plugged in all-day, but in the night, or tomorrow, I run it fully on battery until goes to about 20%.

    If I use this laptop lightly (such as creating/reading/reviewing Microsoft Office files, send/receive emails, browse news, read some PDFs), I can work on this great laptop for working hours a day just with 1 fully charged battery.

    Apple's guide/advice on managing battery life on MacBook is true. My old MBP still rocks and confident to go mobile without the MagSafe. Thank's Apple!
