★★★★★ I have a 7-year old Dell Laptop Inspiron 7520 i7 core that still rocks after all these years, but I had a habit of using it like a desktop and always leaving the charger plugged in which eventually ruined the battery and then recently the laptop stopped recognizing the battery. After I bit of research I tried this one and it was exactly like the old one in fit and finish and just plugged it in charged it and the laptop booted with no issues, notices problems etc. whatsoever. I then let ran it near completely dead for 4 or 5 charge cycles and now it works great. I can now use my laptop on the road again - about 2 hours of hard use before needs a charge.
★★★★★ I bought this battery and installed it into my Dell Inspiron 17R SE 7720 as soon as it arrived.The Laptop booted up quickly and with no screen errors. After the battery charged up fully, I disconnected the charger and used the Laptop in battery. Mode. The battery seemed to hold it’s charge well and the Laptop operated efficiently. It will take time to evaluate the battery life so I am withholding comment on this topic, for now.Given the attractive price and the smooth operation of the Laptop in battery mode, I can say that this was a very good purchase. It also arrived in the exact time promised. I recommend it to buyers who have compatible Laptops.
★★★★★ The battery went right is as expected and computer just took off and the battery worked. Although after the first check we didn't use the computer for 24 hours with the computer plugged in so the new battery would charge up and be ready for use. We liked the results and all is good so far. I did give "battery life" 5 stars but I don't know battery life yet and felt if I gave is less stars then a negative mark would be given without facts. Bottom, I would purchase again if needed.
