T54FJ 8858X Laptop Battery for Dell Latitude E5420 E5430 E5520 E5530 E6420 E6430 E6520 E6530 Inspiron 15R (5520) 17R (5720) 17R (7720) 15R (7520) P/N:M5Y0X N4420 N4720 N5420 X57F1 N3X1D P15F P15G P16G

Perfect fit for my HP Envy 13t-000 laptop. Just got it in. Tom about 15 minutes to install (hardest part was getting the back off). Works perfectly. Would purchase again!

It was difficult finding a fit for my 2020 HP Spectre x360 with my specific model number. After nearly 5 years of flawless performance the laptop stopped charging to 100% and then after less than a week died and wouldn't boot all the way up. I have never owned a laptop where it doesn't work even when plugged in due to an internal battery failure. However, once I took the bottom off and placed this new battery, Viola. It worked right out of the box. And it only took one instance of draining the battery to around 5% for it to charge all the way to 100%. I did drain it a couple of more times to around 20% to fully activate the battery. So far so good. But it's only been a week..

Well I plugged it in and it worked. No issues with the installation. It charged up with no issues. It's still working. Not much else to say.

Good fit and quality.

Easy to replace with some YouTube instructions on how to get my laptop open.The paddle tool is kind of wimpy and broke in multiple places while trying to get my computer open.

I was originally very happy with this battery that I purchased on April 22, 2025. Now only 2 months later the battery is not working right. I have done all the battery testing and calibration that I can find to do on my laptop to no avail. There were a couple days where the battery charged back up to 100% and seemed like it was working again, but that only lasted a few days and now the highest it will go is 26% and that's with keeping it plugged in while using it. Sometimes it won't even charge that high, or charge at all. If I unplug from power, the battery will quickly go to 7% and shuts down my laptop. It never seems to reach 0%, but hangs at 7-9% most of the time. This is UNACCEPTABLE!! The purpose of the battery is so I can use my laptop while not having to be plugged in. What is the warranty on this battery? I'm for sure not looking forward to replacing the battery again so soon. It is kind of stressful going through the steps to replace it. Does this company send batteries that die this soon on purpose? I wish we could chat back and forth with others on here to find out if this is a common occurrence. Maybe the vendor will contact me after seeing this review??

I'm impressed so far!My battery arrived ~70% charged.I drained it down to 5%, charged it up to 100%, and repeated this process two more times.I've been using it for a few days, disconnected from power supply and it seems to hold a pretty good charge. I'm able to go 4-8 hours of continued usage before I need to charge back up.Thus far, this is a 5 star battery replacement in my book.I'll plan to update this review if battery quality goes south in the next year or so.

Honest, reliable seller, and fast shipping Item as described. Highly Recommend
