Before I start, I am aware that Apple's official stance on battery replacements is for batteries < 300 cycles. I am just interested in hearing about anyone who might have had a problem with their battery > 300 cycles w/ Applecare.
The issue I'm having is that the battery fluctuates in its max charge rating from ~700 to ~2600. This issue started a few nights ago when my laptop just started powering down by itself with plenty of battery life left (anywhere between 70-90%). I've tried recalibrating and resetting SMC or PMU (whatever they call it now).
Every time I power on the computer with the magsafe after one of these random shutdowns the battery shows up at 0% and the aformentioned ~700 max charge. Unplugging the magsafe after a few minutes time oddly enough results in the battery jumping back up to ~2600 max. For example, I pulled these two stats from System profiler while writing up this message:
Charge Information: (After random shutdown)
Charge remaining (mAh): 31
Fully charged: No
Charging: Yes
Full charge capacity (mAh): 698
Health Information:
Cycle count: 503
Condition: Fair
Battery Installed: Yes
Amperage (mA): 1032
Voltage (mV): 12530
Charge Information: (After random shutdown and a few minutes charging and then removal of magsafe)
Charge remaining (mAh): 2121
Fully charged: No
Charging: Yes
Full charge capacity (mAh): 2680
Health Information:
Cycle count: 503
Condition: Fair
Battery Installed: Yes
Amperage (mA): 902
Voltage (mV): 12540
Is this basically an indication that my battery is totally shot or is there anything left that I might be able to try? If the former, have any of you had any luck with getting Apple to do a replacement even though your cycle count was above the norm?
I've had this laptop about 1.75 years (22 months, coconut battery shows 47% health ugh...) and my cycle count seems to be way above what everyone else posts. That being said I don't own a desktop so I guess that could definitely account for things. For those who've had their MBPs for awhile, how long does the initial battery usually last you?
