Is this a battery or logic board issue?

I've been having what I hope to be battery issues for several days.  The problem started when I noticed that the battery wasn't charging even though the power cord was plugged in (I have several power cords, so the problem is not with the power supply).  After finally getting the battery to begin charging again, if I remove the power cord, my MacBook Pro immediately shuts off and I am unable to get it to turn back on again (or begin recharging again) without resetting the SMC:

I have had to do this several times in the last day or two.  Going to About This Mac > More Info > System Report > Power, here is the Charge Information:

 

Charge Remaining (mAh): 10038

Fully Charged: No

Charging: Yes

Fully Charge Capacity (mAh): 10523

 

Health Information

Cycle Count: 1055

Condition: Normal

Battery Installed: Yes

Amperage (mA): 1658

Voltage (mV): 8365

 

The laptop is less than 4 years old, but Apple Care ran out last year.  Are there any other tests to determine whether the the battery needs to be replaced versus the issue begin more serious (i.e. logic board)?

    I don't think it's the logic board, but the battery doesn't really look bad either (health "normal", even after 1000+ cycles).

     

    You should probably run Apple Hardware Test...

    Regardless of the battery's stated condition, that is a lot of cycles. At its end of life the battery's state of charge indicator will become unreliable and the battery will refuse to charge properly.

     

    If possible I would bring it to an Apple Store to determine if the battery is in need of replacement, and have them install it. Apple is the best source for replacement batteries anyway.

    I recommend you go to Apple. That's what I do, and I can recommend nothing else. Really.

     

    Yes, they are more expensive to buy. They are the least expensive to use. Yours lasted four years, and you should expect another four from a genuine Apple battery. This is 60¢ a week.

     

    Aftermarket batteries are a crapshoot.

     

    This is my personal experience and my recommendation. Others will have theirs.

     

    Edit: I checked the iFixit website, which I recommend in general. If the are not showing any Apple batteries in stock, there is probably a good reason for it. I am guessing they are unable to find genuine Apple batteries at a price competitive to Apple's, or they don't want to sell the aftermarket knockoffs due to their dubious quality. Apple's QC is uncompromisingly strict. There is a reason they cost what they do.

    Apple has no batteries for a 2010 MBP?

     

    Check here and select "Battery Replacement":

    It is reasonable to expect that you should be able to make a reservation and have it replaced while you wait:

     

    In general, the following replacement times apply:


    Apple Retail Store

    Depending on inventory availability this may be replaced the same day. Make a reservation to meet us at the Genius Bar.

    Call first to be sure they do. Your store may have an automated voice-recognizing robot but they're actually pretty good at speech recognition.

     

    If you cannot wait and still want to consider an aftermarket battery anyway, here is another link:

    Your MBP must have an external battery compartment for that one.
