Futurebatt Laptop Battery for Asus A32-K55 A33-K55 A41-K55, ASUS U57A A45 A75 K55N K45 K55A K75 X55 X55A X55C X55U X75 R500A R500V

Fits perfectly. Solves a long time problem at minimal cost. Battery is purely back up, but necessary. Arrived 80% charged. Would buy again, let's hope I don't need to.

Excellent product! It help my computer.

Worked right out of the box. When I replaced the old battery with this new one on a 10 year old laptop, I forgot to check the power adapter to see if it was charging the battery. Later I checked the battery and discovered it wasn't charging. Oops. I forgot to check to ensure the power adapter was plugged in correctly to the power strip. Once connected the battery was beginning to charge. Averted a problem by checking to make sure my laptop was connected properly.

So far, so good. I appreciate that there are replacement batteries available; The battery fit well in my old mid-2010 MacBook. It powers the laptop for about the same amount of time as the one I removed. The reason I replaced the old battery is that it was swollen, making the touchpad difficult to 'click'. Otherwise, I wouldn't have changed it--the old battery still held charge for several days and powered the laptop for a few hours.If previous purchases of aftermarket laptop batteries are any indication, I should get around a year of good performance and another year of so-so performance. I'll update this review in about six months.Piixel Pusher 20231112

Very satisfied with my purchase

Apple is notorious for trying to keep people from upgrading or replacing their own hardware. Don't believe me? Look at modern macs that won't even let you replace the SSD. Crazy. This older macbook from the 2010-2011 era is an exception however, with really easy to access components. I've heard that some versions of mac osx are picky about the battery you install, as apple adds a chip to the battery to help manage power consumption. Whatever the reason, this battery doesn't have any issues. It has been installed in my sisters macbook over a month, took me 5 minutes to install (Seriously, all you need is a phillips screwdriver and 5 minutes). I got her the macbook second hand for $50, so I didn't want to spend a ton on a battery. That being said, I don't know what kind of battery life these things realistically got when new, but she's averaging 4-5 hours now. Pretty good! If you want to bring an old macbook back to life, this is a great choice.NOTE: It was clear the construction of the battery CASE was a bit flimsy. The plastic tabs holding it together weren't strong, and it was already splitting when I got it. I don't consider this an issue, and neither should you. The internal battery is high quality, and you'll never see the casing. This is a budget replacement item that goes inside a computer, so asthetics don't matter to me, and they shouldn't to you. That being said, I know apple tends to attract a, how do I say this.... "Picky" user. But theoretically those type of users upgraded to the newest macbook pro and ditched this thing long ago. Still worth noting. Enjoy! #PCMasterRace #AppleMakesMeCry

Terrible battery. Have only used it for 4 months and my laptop shuts off spontaneously. Convenient that it stops working right after i can stop using it.

good but not holding 100% when charged
