HT03XL L11119-855 Laptop Battery Replacement for HP Pavilion 14-DF 14-CE 14-CF 15-DA 15-DB 15-CS 15-DW 17-CA 17-by 15-CS0053CL 15-DW0033NR 15-DA0014DX L11421-542 L11421-2C2 11.4V 41.04Wh

I bought this battery for my HP Spectre x360, and it has worked out really well. Installation was straightforward, and the battery fit perfectly without any alignment issues. Once installed, the laptop immediately recognized it, and the charging cycle behaved normally. Performance has been excellent so far. The battery life is noticeably better than my worn‑out original, and I’m getting several hours of regular use on a single charge. It also holds standby power well, which is something my old battery struggled with The build quality feels solid, and the capacity matches the advertised specs. For anyone trying to extend the life of their Spectre x360, this is a reliable and cost‑effective replacement

The battery installation was easy and it's been working great for about a month now. The dimensions appear to be identical to the OEM and everything aligned properly. It retains a charge much better than the older battery it replaced, which is to be expected. The price is right and the little included screwdrivers are surprisingly good quality. Make sure your laptop is completely powered off and not in hibernation before the installation process begins!

UPDATE - Messaged seller & was shipped a new battery. Arrived in 2 days. As an Amazon seller myself I appreciate good service like I provide MY customers. I added 2 stars back. 2nd Opening of the laptop was MUCH easier than the 1st. Old battery had a swollen cell which caused all kinds of issues with computer from mouse not working to machine not turning on even when plugged in. Installed new one. Everything works fine. We will see how long this one lasts. - UPDATED REVIEW - After 6 months this battery is KAPUT. Didnt even get a year out of it. A battery should last WAY LONGER than that. So, NO , I would NOT recommend this battery. I will have to replace my battery once again, which they have turned into a complete PIA by installing them internally. What a pain int he butt. I will be looking elsewhere. Update: they will be sending a replacement. No hassle. No return of old one . Just a pain opening computer & damage it causes by doing so. Small crack from last one. PIA. Wish they would go back to external batteries. Truly a pain.

Great battery. And it was good to have the small tools included with the battery.

Reviewed on May 3, 2026: Pictures of the original/factory HP and the new battery are attached. I have installed the new battery exactly as per the written instructions provided with the battery and have also reviewed several YouTube videos. When I plug the computer into the wall, the ORIGINAL HP factory battery's light on the right side by the cable turns orange until fully charged, then turns blue/white when fully charged. With the NEW battery manufactured by Efohana, when I turn on the computer, the light goes immediately to blue/white instead of orange as it should. The new battery does not charge, and the computer/hard drive does not work. To try to solve the problem, I removed the new battery, turned on the power, and completed a shutdown per the instructions on the Amazon page. I then REinstalled the new battery and turned on the computer, but the same problem occurred: a blue/white light, no orange light, and the computer/hard drive would not turn on. I have attempted to make contact with the manufacturer via Amazon. If I don't hear back within a reasonable time or the manufacturer is unable to help solve the issue, I will return the battery to Amazon for a full refund. I'll update this review as necessary! Update on May 4, 2026: Efohana, the manufacturer, responded timely and stated the following: "Dear, We are very sorry for the problem with the replacement battery and the inconvenience it has caused you. We will arrange a full refund for you directly. No need to return the item. Once again, we apologize for the unpleasant experience." What I don't understand is why the manufacturer, Efohana, has not contacted me to help resolve this battery issue and, if this battery is faulty, provide me with a no-charge replacement under warranty via Amazon. When I sent my request for help, I even included my WhatsApp number so they could call, but they have chosen not to. This is not the way to help and keep a customer; simply providing a refund is not enough. Now, I have to find another battery manufacturer on Amazon, wasting more of my time! Do NOT buy an Efohana battery unless you want to possibly be inconvenienced, as I have!!

So far, so good in dell G3. Didn't include the cable on the battery (used to those coming with the battery from doing repairs on laptops in the past), but it was easily taken from the old battery. Currently in the discharge/recharge cycle, but new life in an old laptop. No issues with size or compatibility.

perfect replacement for my Lenovo laptop... battery life now back to 6+ hours... instead of about 20 minutes...

I have found it does not hold a charge for more than about an hour or two. I'm guessing they cut corners on making these.
