My HP Pavilion laptop's original battery had degraded significantly, making it almost unusable without being constantly tethered to a charger. After some research, I decided to try this Futurosp HT03XL Laptop Replacement Battery, and I'm incredibly impressed with the results. The compatibility list was extensive, and thankfully, it was a perfect fit for my HP Pavilion 15-CS model. Installation was straightforward, especially with the included tools, which was a thoughtful and very helpful addition. Even for someone not highly technical, the process was manageable. Since installing it, my laptop's battery life has been completely restored, feeling like it's brand new again. I can now work for hours unplugged, attend meetings, and move around without battery anxiety. The charge holds well, and it seems to deliver the expected performance. It's a huge relief to have my laptop's portability back. For anyone with a compatible HP Pavilion model struggling with a dying battery, this Futurosp replacement is an excellent, cost-effective solution. It performs as advertised, is easy to install, and truly revitalizes your laptop's mobility. Highly recommend for breathing new life into your device!

Perfect replacement for an original battery in a HP Pavilion 15-cs0064st laptop. The tools needed to open the laptop (screwdrivers and guitar pick) were included - a nice touch for those that don't have the specialty screwdrivers and something to safely pry the laptop bottom off. Fit for the replacement battery was perfect; the places for the hold-down screws lined right up. If you do the HP battery check, you'll likely receive a "battery failure" error message, but don't worry - the replacement battery charges, holds the charge and provides the correct voltage and amperage to power the laptop just fine. I suspect that there's a chip in the OEM batteries that identify them as HP OEM batteries, which, of course, this battery is not. HP is famous for doing that with their printer cartridges, so it doesn't surprise me that they would doing that with their other replacement products. The only question is how well this battery performs over time - we'll have to see. After two weeks, so far so good!

I watched a YouTube video before I ordered the battery. The guy used and old credit card to separate the laptop bottom. When I got the kit with the pick, I thought cool, I can use that instead of a credit card. Unfortunately the pick wore out and didn't do the job. An old credit card did work much better. BTW I also upgraded the memory while I had the laptop open. Worthwhile doing that as the laptop isn't fun to open up and it runs much better. Update: Almost a year later, my battery developed a quirk where it would all of a sudden shut down randomly. I contacted at customer support, which within a couple of days had a new battery to me. Their customer service is excellent. I was so happy they have a one-year warranty.

I got this battery on 06/2025. It fit perfectly and was working fine for a few months. After a few months, I noticed that the battery was making my computer slower, heating up more easily, and lagging more. This also becomes extremely clear when the laptop is plugged into power. It just makes it worse.

OK. 2nd Update. PLEASE READ. After being contacted by the Seller through Amazon, FuturoSP sent another battery completely free of charge. I replaced the one that was sent first with the free replacement. I've carefully completed the 'break in' for the battery as per the instructions from the Seller. So far, so good. The replacement is working very well and we'll see if there's any issues in about 1.5 months. Thank you FuturoSP for rectifying the situation. ************ UPDATE! PLEASE READ! After purchasing this item August 18, 2024 the brand new replacement battery DIED yesterday. Returnability (if that's a word) ended September 19, 2024. I've tried all the "DIY" troubleshooting recommended with no positive results. Battery has dropped to 10% and will not charge. There is no option for a refund at this time. The battery lasted ~46 days. ************ Original review: 2016 HP x360 Spectre 13-w0xx OEM battery replacement. It came with the correct tools to open my laptop and well packaged for battery safety. You may need a sharper edge to get the feet off than the tool that is suplied. After 'Tubing a couple of videos, it was an easy replacement. I've done the suggested break-in procedure and so far my laptop has gone from ~1 hour on the original 8yo battery to ~6 hours on this one (so far... according to research and this battery manufacturer, my battery software will learn the new battery and give me more accuracy in about a week which should lead to a longer "displayed" battery life/actual longer running time, according to the software). When new, the OEM battery would last about 6-6.5 hours of nonstop unplugged use. This battery it spot on so far.

All I can say is wow, this worked perfectly. Charging up now right after install, batter put in was right at 76%. Make sure to search on YouTube or Ifixit. Very simple to do. I wish I had done this years ago. I will charge this up and do battery calibration in the system settings at startup next time to maximize this battery. Perfect replacement. Let's see how long it will last. Just be ready for the computer upon rebooting after installation of the battery to give a CMOS error, just choose enter to reboot and after that your golden. You will be logged right back into your Windows laptop without fail.

Excellent replacement for my older HP. Exact fit. Runs just fine and has the same charge ratings as the original. Installation will be on the installer because not everyone has the same skills. I found it an easy replacement. There are many YouTube videos available. Just make sure to keep track of your screws and extra careful with the cables. Very good price!
