7200MAh 10.95V Replacement Laptop Battery For MacBook Pro Early 2011, Late 2011 & Mid 2012 A1382 A1286 15 Inch Core I7 Review

The battery came with a zero percent charge! Returning it!Sometimes, a Li-ion cell can be recharged after it had experienced 0V, but it will have a lower capacity and shorter life. Most of the time, when a Li-ion cell is down to 0V, several things happen:Some of the copper current collector dissolves, and then plates out on some of the electrode surfaces. If severe, it could cause shorts within the cell. This also reduces intercalation (capacity).Some of the ions in the electrolyte from…

I was surprised that the battery was heavily discounted when I brought it. It was almost too good to be true. It worked fine for the first few days. The Mac’s battery life went up from a few minutes to nearly 3 hours. I have a few other machines so this Mac does not get used much. Recently, when I used it again a few times, the battery is de facto non-existent. The machine shuts down the moment it is unplugged. I reinstalled the battery but to no avail. Am disappointed.

I don't do reviews often, but after my 30 day experience, and a recent change of battery, I felt compelled to speak on the difference.The product is as easy to install as any other battery. Comes with two cheap but *do the job* screwdrivers that help with the installation. First thing I noticed during and after the calibration period (because you should be calibrating your battery to maximize its life) was that my battery indicator light on the left of my macbook (reading this review you should

Pleased with the product. The battery fit perfectly. I was delighted to discover that it shipped with the tools to install.

It’s a perfect fit.I did charged it and then fully discharged.It’s working fine, will wait to see how it works with ime. Thanks for attention.

I want my money back or send me a new battery because the one I got didn’t even last 6 months. The battery will not charge anymore. What a waste.

Originally, I had a defective battery, but the vendor was extremely professional and promptly sent me a new replacement. The battery performs very well now!

After only 14 months my mac is now saying "Service Recommended”… and the battery is draining so fast now. I thought this would last at least two years. Waste of time!

Battery installed easily enough. It even charged up all the way. The battery life is somewhat disappointing. Better than having no battery at all like before due to the swelling but more than an hour is pushing it.

This product was easy to install. I'm so happy that my MacBook that has been sitting in my closet for the past 3 years could be brought back to life!

My Mac laptop would reboot constantly and the battery would not hold a good charge.With this battery, my laptop came to life. And the holds a charge to 4 hours while had many apps running.I let the battery drain to 0 and recharged in on time.Great product!I would buy this batter again for other repairs

So far so good! Install was easy and after I gave the battery a full charge, it head really held on to the charge like my new computer does. I’m very happy with this battery so far, and so glad that I can now use my old MacBook again!

Installed 1 battery on mid July. The battery died within 2 weeks. I returned and installed another mid August this one died over night. My computer now will not turn on even when plugged in. I would like my money but the product is outside the return window.

It holds the charge very well, and seems to last as long as the original. The screw holes didn't align as well as the original but just required some gentle finagling. Good value! So far so good.

I purchased this battery to replace a dead one and it takes so long for this to fully charge. It took 12 hours for it to get to 50%.

I bought a rayhom battery and compared it with a Vinpera battery, and found that the material is different. In order to be able to use for a longer time, I believe that high prices can provide better quality

Finally got the chance to install this replacement battery but unfortunately it didn’t work. Upon installation its showed 36% so charged the battery overnight then in the morning it still showed 36% then laptop starts then shuts down again.

The fit was perfect and gave new life to my MacBook 15 Early 2011. The computer became quick again. The battery life was only about 6 hours, clearly less than a new computer but not terrible. The life quickly dropped off. 9 months in, it struggled to hold a charge at all, but was okay since I used it plugged in most the time. Well at 10 months it died completely and made the computer lag so terribly that it has made the computer useless. I tried to write the review on that computer, but it was…

It won't hold a full charge anymore. Thankfully this is returnable and within the amazon return window. It was easy to install and everything fit well, but it won't fully charge anymore. I can leave it overnight and it still only reaches 98%. I am returning it. I'm guessing if I continued to use it I would see the battery continue to degrade and eventually fail or become as useless as the one it replaced.

excellent replacement battery. No issues what so ever. Easy to install. Restored machine to a fully functional state. Machine was not functioning correctly with the previously dead/failed battery even when plugged in.
