inspiron n5110 battery backup problem


Sep 9, 2016
I have a dell inspiron n5110 laptop. now i have changed my laptop battery and its charging as normal battery but even after getting full charged laptop gets shutdown within 2 min. we can't expect this poor backup from a new battery. please help me what should i do to fix this issue.
basically it's the incorrect model or it's a defective unit.

Chances are it's a defective unit because it's easy to google "N5110 battery" and find supposedly compatible models with customer feedback stating it works.

Also, and not sure, but I think incompatible models might not physically fit.
