DELL 357F9 Notebook Battery for DELL Inspiron 15 5000 Gaming 5576 5577 15 7000 Gaming 7557 7559 7566 7567 Laptops 357F9 71JF4 0GFJ6 071FJ4 00GFJ6 P65F P65F001 P57F P57F003 11.1V 74Wh 6Cells

It has all the markings of a real Dell battery, identical to the original, except that the original was marked as cells made in Korea and assembled in China. This battery has cells made in China and was assembled in China.The date code has it as 8 months old, which seems like a very young battery. I didn't do a full capacity test, but the charge does not deplete faster than I would expect. On my lite 'gaming' laptop with two fans and a GPU, all settings set to maximum performance, it seemed like it would give about 3 hours of runtime starting at 100% SOC. That was on a 5 minute test starting at 80% SOC.

This battery is exactly what is needed for a Dell 7567 gamming laptop. Comes as the 11.4 volt just as the old battery is.

This “original Dell” battery is garbage. It only holds for 3 hours or so when just browsing and watching YouTube. My last battery that I bought for $30 lasted almost 8 hours at the beginning, and it wasn’t even a Dell battery. This a scam. They either sell poorly made unofficial copies or just buy the used ones and re-sell it to us. Mine came fully discharged, so that was already a sign of caution.

Fit perfectly, all is well!

I got 4 months of good battery life out of this for my Dell Inspiron 5577 (~5:30 hours), then a massive drop in performance (2:30 hours) with medium use.The battery reading is inaccurate. It says 3:30 h at 100% then 2:30 h after dropping 10%.Also the battery is swollen.The Amazon page says 12 month warranty but there's no contact info on the manufacturers Dongguan Electronics to get a replacement. This is a cheap product with zero support and an unreasonable price tag.

I think it is realy oruginal item. I did not instal it yet, but its looks fine and new

It has been a month and the battery is working good
