My mid-2010 MBP is saying I need to replace the battery but when I look at the battery in System Information I see this:

Charge Information:
Charge Remaining (mAh): 0
Fully Charged: No
Charging: No
Full Charge Capacity (mAh): 4580
Health Information:
Cycle Count: 117
Condition: Replace Now
Battery Installed: Yes
Amperage (mA): 0
Voltage (mV): 8242

It's saying it's installed, a low cycle count, and a full charge capacity of 4580. I don't understand why this battery needs to be replaced. I am running OS X Yosemite. Can anyone tell my what might the issue be? I don't want to pay for a battery replacement if it doesn't need it.
 
117 cycles seems very low to replace a battery - could be a defective battery. If you've had it since 2010, maybe you haven't used it off of your charger enough. If the battery is not being used, it will degrade.
 
I would go to apple for a battery replacement fairly soon. After Apple considers your computer vintage (5 years after discontinuation) they will no longer offer their battery replacement service, and third party batteries can be hit or miss in quality.

If there is another problem, Apple should be able to diagnose it as well when you take it in.
 
probably defective battery. I just changed my 2010 with Key Power battery from Amazon. Holds charge well!

Full Charge Capacity (mAh): 6121
Health Information:
