Macbook Pro - Battery Calibration Question

[russell_jt]

I recently the upgraded the battery in my 2010 MacBook Pro, however I'm not getting the performance that I expected. I still only get about two hours battery life tops.

I have read the Battery FAQ on these forums, and have tried calibrating the battery but this does not appear to have resolved the issue. Is there any way that I can be sure that I calibrated it correctly?

Many thanks
Russell

Which battery did you buy?

Since this is not a user-replaceable battery, there is no need to calibrate it: https://support.apple.com/kb/PH14087?locale=en_US

Calibration only has to do with the metering of the battery, i.e. how many percentages of remaining juice the OS reports.
If you let it run out, leave it a bit, then charge it fully and leave it fully charged with the charger in for a bit, you've done it right. Lithium-Ion batteries really don't like getting run dry though.

I think you've just gotten a bad battery. Where did you get it from?

Understood - I wouldn't be surprised if it is a bad battery then; I didn't purchase it from apple.

Are there any tests I can perform to determine whether it's holding the amount of charge it is supposed to or any other performance metrics?

System Information should show the capacity. Coconut Battery also gives details. I don't know if the sensor for this is part of the battery itself though in which case it could theoretically lie, so your only option then would be to measure the used power and calculate the charge
