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!

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.

Exact fit, easy install, works like new 👍

This battery worked great. I installed it in a Dell Latitude 7400. The first two times I installed it, it was not charging correctly. I was getting blinking yellow warning lights on the laptop charging light. The solution was that I did not have the connector cable on the laptop completely plugged into the battery. So it was a bad connection issue. Plugging the cable firmly into the battery resolved the issue.

Instantly improved the battery life of my 4 year old Dell Precision 5550. Fits exactly where the old one does and works great. Can’t speak on longevity yet but so far so good after a few months.

WORKS WELL AND IMPROVED COMPUTER SPEED

As advertised, easy to change out, fit perfectly.

Worked good right out of the box. Easy to hook up. My laptop now has power for many hours.

Ya tenia mas de 6 años con la bateria de fabrica de mi laptop y la bateria ya solo duraba 15-20 minutos, por lo que siempre necesitaba tener un enchufe disponible para poder trabajar con mi laptop. Estoy probando como me va con esta nueva bateria. Para empezar ya hice el ciclo completo de carga/descarga y mi percepcion fue que se renovó la vida util de mi laptop. El primer ciclo se cargo bastante rapido con un cargador original de DELL (El de mi laptop) y la batería duro alrededor de 7 horas. Durante ese tiempo tuvo periodos de consumo alto usando AutoCAD y Excel (Libros con bastantes registros). Me ha funcionado perfectamente durante estas semanas. Si algo llegará a fallar, actualizaré la publicación. Recomendación: Validar muy bien el modelo para evitar comprar una bateria no compatible.

Perfect fit on my daughter's older DELL laptop. Works as good as new.

bon rapport qualité-prix
