No puedo opinar sobre la vida útil o la longevidad de la batería porque recién la acabo de instalar en reemplazo de la original.

Solid replacement.
Price point is great, installs easily, macbook recognized it without issue. Tested well for the first few cycles. I have not tested it long term, but I will report back.

Perfect Replacement for Swollen Battery
This procrastinator received the internal battery on a Monday, chose to just go ahead and deal with replacement since tools were included. Having replaced a hard drive and expanded with a second one I’m no stranger to opening a MacBook Pro. Battery in this case had swollen so horribly that it disabled the trackpad’s ability to click.Two different sized screwdrivers loosened the bottom screws and then the larger ones retaining the old battery. All it took was unplugging and removing and then seating the replacement.Instructions say to allow the new battery to deplete to 5% and then charge to 95%. Sorry, I’ve allowed it to charge completely. I’ve unplugged the power cable to deplete again, but this battery works as designed and I’m thrilled that it only took about 15min for complete installation.
