Paid premium price hoping it would last longer. Initially worked great. But after just over 1.5 years the battery last 2 hours on an average.

Lasts less than 2 years

Perfect-fit battery replacement for a 2012 MacBook Air that I'm upgrading because... it's old enough that you still can!  Easy install, it took about 5 minutes total & most of that time was unscrewing all the screws from the bottom case.

OEM Fit & Finish.  Easy Installation!

Battery didn’t come charged so it was difficult to tell if installation was successful.

Battery uncharged.

The battery is excellent. Brought back our laptop to its original capabilities.

Excellent Battery

I purchased this battery in Nov 2018 and have waited a full 2 months before writing this review. This allowed me to fully test the performance of the battery.
This battery is rated at 55 Wh capacity which turns to around 7200 mAh @ 7.6V.
I have monitored my battery throughout this period and it has cycled for 30 times during these 2 months.
My battery came in at 0 cycles and it has 7332 mAh capacity at the beginning. After 30 cycles I still see 7331 mAh capacity.
This is great because most of the poorly built batteries lose their capacity very rapidly. It is not the case with NuPower battery.
Installation was a breeze. Just unscrew the bottom of Macbook air and unscrew 5 more screws holding original battery. Replace with new battery and put the 5 screws back. Of course plug in the battery cable.
And there you are, a fully functional new battery. Now I regularly get 7-8 hours of use out of my 2011 Macbook air.
I give 5 stars to this product.

This is an awesome battery

This is my 2nd newer tech battery. The first one only gave me
 1 hour after only 275 cycles/2 years old. This one, like the old one, is fine when new but for how long?
Great price and it's far better than other cheaper batteries on 
the internet.

2nd battery...hope this is one better

Battery fit well, worked well, very happy.
