Re: MacBook battery replacement
Cycle count is 278 and Condition normal so I suspect a replacement battery in the next little while may be a good idea and bring benefits. Thanks again, another hidden bit of very useful information!

The built-in batteries for the unibody machines are rated for the 1000 cycles. The MacBook is still on Snow Leopard so I can not do the check you suggest. Yes you can, it’s almost identical to check the battery in Snow Leopard only difference is in SL it is System Profiler in Lion it is System Report.

Re: MacBook battery replacement
I haven't. The Batteries from China are cheap for a reason. I purchased one a while back and almost immediately regretted it. When that battery was installed the machine would shut down unexpectedly with anywhere between 10 and 20% battery charge left. And shut down hard. No warning just turn off with that awful sound of the HDD trying to dock itself with the remaining battery power. I wouldn't recommend the Chinese MacBook batteries. With batteries you get what you pay for.

Re: MacBook battery replacement
Hello Severin There was an issue with faulty batteries with MacBooks made at this time. The batteries would not hold a charge if left flat for extended periods. Or if charged from a later model charger. A BATTERY firmware update 1.4 was released and solved the problem. However many people did not know (including me) that the battery firmware update was necessary BEFORE updating to Snow Leopard and especially Lion. There is a problem running the update on later operating systems and its caused lots of headaches. Though there is a work around. First you need to check if this applies to your MacBook. Instructions for battery firmware update. http://support.apple.com/kb/ht3421 http://support.apple.com/downloads/Battery_Update_1_4 But it does say System Requirements Mac OS X 10.4.11 Mac OS X 10.5.6 but NOT 10.6 or 10.7 Many people have tried to update the firmware on Lion and are really frustrated with the lack of a results. Two good articles here. Though they are not up to date, they are still worth reading. http://www.all-about-apple.com/macbook-battery.html http://www.all-about-apple.com/battery-time.html If this does apply to you, a new battery could respond in exactly the same way and in some cases, not hold a charge at all. If this applies to you please get back to the list. There are more articles on Google about how to tell if your firmware is up to date and suggested work arounds.
