Review: Great Replacement Battery for Dell XPS 13 9360 - Battery installed in a matter of minutes. Arrived fully discharged. After overnight charging, my laptop is again running great. Battery meter indicates 100% charged. Very pleased!
Review: Fit Alienware 17 R4 - The battery on my 2017 Alienware 17 R4 was completely dead. Upon opening the case, it was puffy...and obvious sign of expiration. I bought the Fancy Buying HF25D Laptop Battery for Dell Alienware R4. It exactly matched the OEM battery, and fit perfectly in both size, shape, and connection. The kit even included a small screwdriver, though I used my own tool set. The laptop fired up with no issues, and immediately started charging. Within an hour or so the battery was fully charged, and as instructed, I unplugged it to let the battery discharge. I don't expect it to replace the OEM battery perfectly in terms of power storage or longevity, but the laptop is nearly nine years old. If my 12-year-old son wasn't using it for gaming, it would already be at the recycling center. This affordable battery replacement will extend the life for another year or two until we are ready to get him something better.

### ⭐⭐⭐⭐⭐ Great battery
*by J***Y on September 6, 2025*

Battery works great! Brought back to life an XPS 13, perfect fit and compatibility. It had 72% on install so I was able to test it for the few hours it estimated it had and was pretty spot on. Charged it to 100 no issues. Definitely worth the money
