Dell E7240 Battery Replacement

Hi All,

Wondering if anyone here has ever needed to replace a Dell E7240 Battery and bought it from eBay or another online site?
I can't find this particular model/part number on the Dell site.

Part number is: WD52H - 31Wh 11.1V

Found some listings, just not sure which to get so I wouldn't get scammed or what not:

I'm leaning towards the eBay one, cause the image has clear specifications showing it's the same part number. What do you guys think?
