Battery replacement topic

Hi guys, has anybody of you tried changing their N5's battery? If you did, where did you get the replacement?

My N5 has been showing signs of severe battery degradation. It's easily discharged. I'm finding myself charging it two to three times a day. Even on standby, it discharges a lot even there's no wakelocks I'm seeing from betterbatterystats app. Its been a year since I bought our N5 so I guess it's time to replace its battery.

I'm seeing some batteries from eBay but would like to know from where you get yours and how's the quality compared to the original default one.

Thanks.
