I noticed the post is a year old but this might help others.
I had issues which lead to the final issue of slow charging. Long story short, changed my keyboard with a poor quality one. Some key were not working so I decided to pull the battery connector while under load (while powered on). This shorted my battery showing X on the battery icon. Changed the keyboard with a quality one.
I purchased a new battery but was for another Mac model, was still was not working with out Magsafe charger. Having left that battery in appeared to short my Magsafe charger.
I purchased a battery and charger which both was said to be genuine, however charging was very slow. Took over a day to charge and would power down in 2-3 hours. I decided to order a top battery, NewerTech which was the one I had before that I shorted.
Still having slow charging issues, so I purchased a charger directly from Apple. When connecting the first charger which was said to be genuine, CoconutBattery states charging with 2.98 Watts but when connecting with the charger from Apple it states charging with 5.86 Watts then goes up to 6.08 Watts.
I have only installed the new battery in today and started to use the new charger. I am yet to calibrate the battery with the MacBook Pro today. However already showing signs of charging at a faster rate.
Maybe purchase a charger directly from Apple, it will be a good investment and might well solve your problem.
However, I will feedback my findings once I have calibrated my MacBook Pro.
