The Setup: Why I Needed a Replacement The original battery in my Dell Latitude 7480 had completely died, and the machine was effectively tethered to the wall. This laptop still has plenty of life left in it, but without a working battery, it was useless for my son's schoolwork. The goal was simple: bring this reliable machine back to life as a portable, reliable tool without having to buy a new laptop. Installation & First Impressions The battery (model F3YGT, 60Wh) arrived well-packaged. The physical installation was straightforward and a perfect fit for the Latitude 7480 chassis. I had absolutely no issues with the screw alignment or connection. Crucially, the laptop recognized the battery immediately after the first boot-up. Performance: The Unexpected Win This is the area that genuinely exceeded my expectations. I am consistently getting longer runtime than I remember getting even when the original Dell OEM battery was new! The Bottom Line: A Massive Value There is genuinely nothing I can point to as a disappointment. This simple replacement saved us potentially over a thousand dollars that we would have spent on a new student-grade laptop. If you are a Dell Latitude 7480 owner dealing with an aging, dead, or severely degraded battery, stop hesitating. This 60Wh F3YGT replacement is a high-quality, high-capacity solution that restored portability and excellent battery life to a reliable workhorse computer. Highly recommend.

Works well and is compatible with my Inspiron computer. Great value for the price. Would definitely recommend over the name brand to save your money. It was very easy to install, fits perfectly, and the battery lasts much longer than my old one!

This fit my computer perfectly! I have a Dell Inspiron 7706 2 in 1. The battery was easy to change. I would buy this again if needed! My computer is now keeping a charge without it having to be plugged up when I use it.

Easy to install - worked perfectly. The only oddity was that the windows certificate needed to update. All is working well!

It fits my Dell 3583 laptop perfectly. But it did need some work to install it, the screw driver come with the battery did not help that much. It works well with my Dell 3583 laptop very well. It saved my old laptop from several minutes battery time to several hours.

Terrible battery fake capacity and unstable discharge (with real data) I rarely leave reviews, but this one is necessary to warn others. I bought this “68Wh” replacement battery for my Dell Latitude 5501. It installs fine and charges to 100%, but the performance is completely unacceptable. Here is actual data from my battery report: 09:55 → 99% (48,245 mWh) 10:26 → 77% (37,149 mWh) 11:16 → 58% (27,983 mWh) 11:52 → 36% (17,298 mWh) That means it dropped from ~100% to 36% in less than 2 hours of light/normal use. This is NOT normal for a 68Wh battery. In addition: The battery drains extremely fast even in standby. The percentage is unstable and sometimes drops suddenly. Real battery life is around 2 hours (should be 5+ hours for this laptop). I performed proper calibration cycles and updated BIOS, so this is not a system issue. The problem is clearly the battery itself. The reported full charge capacity is far below design capacity, and the discharge curve is inconsistent, which strongly suggests low-quality or defective cells. This product is misleading. It may say 68Wh, but it does not perform anywhere close to that. Avoid this battery and invest in a higher-quality or genuine Dell replacement. You will save yourself time, frustration, and money

Battery works well. Reasonably easy switch out. Battery life between charges is okay, just not as long as original.

Battery was exactly as shown and described, and fit exactly. It arrived on time. This battery was identical to the battery it replaced, and a hundred dollars cheaper than the battery on their company website.
