iProPower A1494 A1618 Battery Replacement for 15” inch MacBook Pro A1398 Retina Laptop, End 2013 Mid 2014 Early 2015

This battery works, and that is the most important point. It's full charge capacity was slightly higher but than the original but this will vary on a per battery basis.After 4 cycles, it had lost about 30 mAh of full charge capacity but I believe the battery is still calibrating. We'll see how the full charge holds up. This is a however a lot better than the replacements I originally bought from iFixit which were faulty and dropped by roughly 200mAh every cycle.

the built the packing and tools are handy, but what a pitty the wrong battery was sent...

I bought this after previously using a battery that tried to imitate the OEM batteries, but landed up going up in smoke. This one however was a much better buy, its not trying to be something its not. Although it looks slightly different to the original battery, it fits fine and works alright. Battery life isn't as good as when the laptop was brand new, but still quite reasonable.The fitting of the battery, is quite challenging, requiring the complete dismantling of the laptop and some very careful use of solvent to try and remove the old battery without damaging it. Not to be done lightly. This is of course the same with any battery replacement for the laptop as that is the way apple have designed it. It's worth noting that official apple techs won't ever replace the battery alone like this, they fit a complete new top casing with the new battery already glued in place, as removing the old battery alone is fairly risky.
