Replacement Laptop Battery

[*Superman*]

I currently have a stock 6 Cell battery which I think has gone to **** because it just told me I would have 24 mins left with 54% of the battery charged. I want to go ahead and buy a 9 cell but I'm not sure what all I should be looking at. I'm also buying one from eBay and found a few that fit my model, just need help deciding on which one to get. Just in case, my model is a Dell Inspiron N5110.

I think this is the one straight from Dell, but I'm not spending 120 on a battery.

I kind of have them in the order which I think they rank. Thinking about going for the first one (from ebay). Also anyone know what WHr means, the dell one says 90 but the third one says 73 if you zoom in.

Amazon has a battery listed for $40.

Anyone of those you listed from Ebay will work. There isn't much to the batteries that you have to look for.

Really just want to know what the mAh and whr mean. I've seen some that have higher number, but also cost more than the ones I listed.

I'm not 100%, but I'm pretty sure that Whr = Watt Hours and that mAh = milliAmp hours.

Both are a way to measure battery capacity.
