Brand new ifixit battery charging extremely slow

Just popped in my new hard drive and battery from iFixit. All went swimmingly until I started to charge the battery. Macbook came up wicked fast. The battery showed 7%. Put it on the charger and 5 hours later I am at 47%.

The old battery was still functional and would run for about 3 hours on a full charge and would charge quickly. I decided to make the switch at the same time as the hard drive since I would be opening up the case. Is this what I should expect for the life of the new battery or is it a first use sort of thing? Any suggestions on how to get the battery to charge a bit faster?
