After about 15 minutes of moderate use I looked at the status bar and noticed that my battery was already down to 79% available. So here I was with a battery a little over a year old, it had a grand total of 54 cycles on it and was down to 79% health. I did some research and heard good things about the NuPower Batteries so I decided to buy one through Other World Computing. Once calibrated, my MacBook Pro’s battery performance was right back to brand new levels.
One interesting aspect of this NuPower battery is what iStat Menu reports in terms of Design Capacity and Current Capacity. I’ve read pretty extensively on Lithium-Ion battery technology and believe that Apple is giving good advice in telling you to rotate off power fairly regularly (at least monthly).
Battery University has some great pages on what can impact Lithium-Ion battery life and heat is as big a factor as anything for long-term battery performance. However if I put my MacBook to sleep by closing the lid, the battery temperature immediately on waking up was registering as low as 75F after a few hours - the same temp as the room it was stored in. I bought a MacBook battery from them which only lasts 2 hours and reports 90% battery health. I am an entrepreneur, full stack software engineer (Ruby on Rails) and general technologist that loves personal computing and devices.

Although the battery replacement procedure is practically identical between lines, specific video instructions are helpful particularly because of the differences in batteries and screws.

I decided that rather than spend it in my office I’d grab my MacBook Pro and take it out on our deck, feel that nice breeze and work through some code.
This particular MacBook Pro is the last generation before the unibody models debuted and as such has a replaceable battery. They issued me a brand new battery and sure enough, I was able to get a few hours (2-3) out of it on a full charge. After a couple of full cycles and 4 weeks of use, the battery reports a design capacity of 5400 mAh, but a current capacity of 5607 mAh. What they don’t tell you is that if you do keep your MacBook plugged in most of the time that the heat of your machine running will also cause your batteries to deteriorate more quickly. That 11F to 19F range is pretty substantial and something I think factored in to my battery’s early demise. You can of course set your Energy Saver preferences to put your machine to sleep after 10-15 minutes of non-use while on power as well.
Searches are carried out in real-time, and from the main page you can easily browse most car makes currently available. If your internet connection is wireless, check the airport menu to see that you are connected to the current network. A mixture of upper and lower case letters, numbers and punctuation is more secure than a password entirely in lower case. Check that the sound output is set to internal speakers (or whatever sound output device you are using).
Back up your information and reformat the hard drive using the disk utility software to use the Mac OS Extended (journaled) format. Check the size of files and folders that remain on your Mac to find large files that are taking up space. Specifically, models from 2009 and 2010 use one type of battery and those from 2011 use another. These batteries are of high quality, are available for worldwide shipping, and include the exact size and type of screwdrivers needed to perform the battery swap. Low quality batteries may not only have a short lifespan, but even could leak or cause a fire.

A little over a year ago my battery started acting up something fierce and Apple was kind enough to replace it, though technically it was out of warranty. I made a commitment to myself to cycle the battery frequently but that only lasted about a month before I fell into my old habit of just leaving the machine running 24x7 and connected to power all the time. This seemed a little self-serving because they use the cycle count (recharge cycles) to determine how old a battery was.
It fit into my MacBook Pro perfectly and I followed the instructions to get the battery calibrated. However my older Apple battery had a design capacity of 5600 mAh but had been reduced to 4442 mAh.
I personally have it set for 10 minutes, however if I know I’ll be away for a bit (lunch, going to bed, etc) I just close the lid. Everything was ideal - so much so that I’m sure photographs of me sitting there would have made for great stock photography for some web site. If I did as my Apple Genius recommended and cycled my battery constantly I’d have 350+ cycles in less than a year pretty easily. One of the better features of Macs is that they wake from sleep reliably and nearly instantly - best to take advantage of that. The whole of the US is covered, and the featured vehicle types that you can have your pick from include convertibles, coupes, trucks, hybrids and station wagons. The old Apple page for my MacBook Pro suggested that after 300 cycles my battery should still have 80% of it’s charging capacity. The new unibody models are apparently much more efficient and are designed to get to 1000 cycles before dropping to 80% capacity. To ensure the safety of the battery charger, 6 safe protections are designed, including overload protection, overvoltage protection, low voltage protection, high temperature protection and output short circuit protection,battery reverse protection.
