Fully M5Y1K 14.8V 40Wh Replacement Battery for Inspiron

I was able to easily find the right batter for the labtop

Not sure if it's the laptop or the battery, but this new one only lasted about 30 days. I am getting a message on the laptop the battery needs replaced. I checked the bios and updated it and ran a battery test and the bios has the same message. I cannot return it for replacement since I purchased on 12/13/2019 and the last day to return was 1/30/2020.

EDIT: Seller contacted me to try another battery. Worked great when I received the new one. I believe the prior one was a dead return...As the first didn’t work at all per a prior review.

it works great

I like it but the screen is darker when running on battery.
