How to Solve Service Battery Warning - MacBook Pro

How to Solve Service Battery Warning

There is only two ways to fix this:
SMC - Static discharge
 1. Take out the battery and disconnect Mag-safe cord
 2. Hold the power button for 30 seconds (static discharge)
 3. Plug-in power adapter & Mag-safe cord, wait until the cord LED is green
4. Put the battery back in
Update:

I have personally just tried my "ServiceBattery" and came up with the "Solved Issue" on my:
MacBook Pro
Mid 2012, 13.3" i5 

 If that doesn't work ... (Contd...)
'Re-calibrate the battery (takes a long time)

 
1. Charge your battery up to 100% until the Mag-safe cord LED is green
 2. Disconnect the Mag-safe cord and run the system all the way out of batteries
 3. Put the computer to sleep (5 hours) to finish discharging the batteries charge
 4. Charge it back up all the way
 Anything else is pointless, it's the SMC services within your system, it's not a software problem.
You can download the "Coconut Battery" from here to check the battery status.

As per Apple.com Instruction:


If your portable Mac has a removable battery, calibrate the battery to make sure that you get the longest running time. When you purchase your Mac, you should calibrate its battery in the first week and then recalibrate it every two months. If you use your Mac infrequently, it’s best to recalibrate the battery at least once a month.

If your portable Mac has a built-in battery, you don’t need to calibrate the battery.

Plug in the power adapter and fully charge the battery.
When the battery is fully charged, the light on the power adapter connector changes to green. If your Mac is on, click the Battery icon in the menu bar to check whether your battery is fully charged.

Keep your Mac plugged in for two hours.
During this time, you can use your Mac or turn it off, as long as the power adapter is plugged in.

Disconnect the power adapter. If your Mac isn’t already turned on, turn it on. Then keep your Mac on until the battery runs down and your Mac goes to sleep.
You can use your Mac during this time. If you don’t use your Mac, make sure it doesn’t go to sleep before the battery runs down.

Prevent your Mac from sleeping

If you continue to use your Mac and you see the low battery warning, save your work and close all apps. Keep your Mac turned on until it goes to sleep when the battery runs down.
After your Mac goes to sleep, turn it off or allow it to sleep for five hours or longer.
After five or more hours, connect the power adapter and leave it connected until the battery is fully charged.
You can use your Mac during this time.
