17" MBP Uni - Battery (mAh): 12000 or 17000 - Check your batteries!

Hey All,

This may be very premature, but it would seem some people are reporting 17000(mAh) on their batteries after calibration, while most are reporting 12000(mAh) or so.

The few with 17000(mAh) are reporting a pretty significant battery life extension over the other people, but it has yet to be determined if this is due to proper calibration, or some lucky users are getting better batteries.

I encourage you all to take a look and post your results. Also, be sure to post whether you have calibrated the battery or not as it may have something to do with it.

Here's how you do this:

- Goto The "Apple" in the Top Left Corner, select "About This Mac"
- Select "More Info..."
- Goto "Power" on the side
- Copy all info from "Battery Information" (Don't need System Power Settings)

Thanks!

PC!!, Windows Vista, Funny,,,it just works!

Hi, Rudolf. Calibrating one's battery does not "cost battery life" except in the same sense that using one's battery "costs battery life." Apple recommends recalibrating the battery "every few months" in this article:

BatteryUniversity.com, perhaps the best online source for information about all types of batteries, recommends recalibrating a lithium-based battery every 30 charge cycles:

why sony?


Because somebody has to make them, and Sony is one of the leading makers. Apple contracts with other manufacturers who make all the parts for Macs, to Apple's specifications. Many parts are made by recognizable major-brand manufacturers; others are made by companies we've never heard of.
