11.1V 48Wh 8858X T54FJ M5Y0X N3X1D 911MD Replacement Laptop Battery for Dell Inspiron 15 4420 7520 5520 5420 5720 7420 7520 7720 E5420 E5430 E5530 E6420 E6430 E6530 N4420 N4720 Notebook

Replacement battery popped right and started charging right away. Have had no problems at all with this replacement.

The description said this this battery was compatible with my laptop. My computer all but told me to get it out as it was NOT compatible. It looked and fit like the one I was replacing except for the word Dell. I took it out and put it back in and still no good for my Dell Inspiron 5720. I thought that I may have not installed it correctly but I got the same computer message that this battery may cause damage. I guess I need to stick with the Dell product. I returned it with no problems.

This battery indicated immediately that it may damage my laptop of I tried to continue using it. The company told me to put it back in and charge it anyway. Not safe advice I don't think. Item was returned for refund.

Ordered it for my dell , everything seems to be working good ... it’s been more than a month and I use it everyday no issues at all ..

Works as its expected to. It's a battery!

Fast charging and life of batter is good!

although product was a replacement and is not much better than the original as far as battery life.

The computer will not recognize the battery, despite many attempts to trouble shoot and resolve the error. Computer will not charge the battery, so it is just as useless as the original battery I was trying to replace.
