The battery had died in wife's 5 year old Asus Zenbook, It wouldn't boot up giving a message on the signon screen about "Too many shutdowns. Power the computer for two hours and try again." I considered just retiring the machine to the recycle bin, but decided to give this replacement battery a try. The new battery fit perfectly and the machine now runs like new again. The installation of the new battery is relatively easy. The hardest part is popping off the metal back plate from the laptop chassis after the screws are removed, but with the included tools and a little patience, I was able to complete the job in less than an hour. I plugged in the power supply and was relieved to see the charging indicator immediately light up. I let it charge for a couple of hours, then the computer booted up without a problem and worked perfectly.

Works well. Seems to hold up. Time will tell.

My wife's laptop started to experience "the bulge" from the battery pack. We bought this kit and had it replaced in under an hour. Everything fit great, and her laptop now closes properly and runs like a champ. Good buy at a good price!

It fit perfectly in my lap top. It was charged @80% when I first received it and suggested to let it drain to 2% b4 recharging. It took 1.5 hrs to drain to 6% b4 my laptop turned off. I’ll see how long the battery lasts by itself after this recharge b4 giving it a different rating. I was hoping for a longer than 2hrs.

This was a great battery for as cheap as it was

Ordered this item and installed it 4 months ago to replace my XPS 15 (9500) battery. Great price for a replacement battery but unfortunately my concern about not buying OEM came true. The replacement battery was always a bit buggy from the day I installed it. My original Dell battery was 4 years old and only lasted 1.5hrs fully charged. The great thing about this battery was that it lasted nearly 4hrs fully charged, however the problem was that when booting up or coming out of hibernation the laptop would suddenly shutoff once every 4-5 bootups. This was very frustrating and fortunately none of my files were ever corrupted. Starting from the 3rd month of usage the problem increased to once every 2-3 startups. I finally gave up when my chances of getting the laptop to startup was 50/50. Once at a client meeting my laptop failed to bootup 5 times in a row and eventually resorted to working off my iphone. My guess is the battery could not sustain the required voltage during windows startup/login and when windows would come on and start loading background apps like teams and one drive the voltage would drop and the system would shutoff. Even after charging the battery for an entire weekend I still had the problem. I removed and reseated the battery several times but still couldn't resolve the problem. The battery definitely degraded quickly over 3 months and roughly 3-4 charge cycles per week. I tested with the laptop plugged in and didn't have the problem, but that defeats the purpose of having a laptop. I eventually removed this aftermarket battery and went back to my old original dell battery for the past 2 weeks. I only get 1.5hr at full charge but the laptop has not shutoff on me once. I'm hoping customer service will replace my defective battery. I'm happy to change my review if I can get a good battery.

Easily installed. It’s working very well and charges up to 3 hours usage the way I use my computer. Charges quickly. I’m very pleased.

ordered for the toshiba laptop c655 and was a perfect fit; timely shipped, laptop works again
