Choosing battery replacement for non-retina MacBook Pro
I would ensure that you purchase a battery from a reputable online store dealing with Apple products.

For example, the following are some well-regarded sites:


Mac Sales 
Simply Mac
RAM City
Macfixit


By buying from a reputable store you'll be sure to get a battery fit for purpose, regardless of manufacturer. Being reputable means they're only going to sell something that works and they'll stand behind the product they sell, regardless of the brand.
