New Battery for Nokia 5 TA-1024

Does anyone know where I could buy a Battery for a Nokia 5 TA-1024 cheaply and what Tools do I need to buy to insert the Battery.... Only seems to be a few on Ebay and don't know what I'm looking at or for. T.i.a. Hopefully a new Battery will be the end of my charging problems. If I end up stll messing with Chargers after buying a new Battery there is no hope for me.

And I might buy a new Screen altogether myself as well that somebody else linked me to besides farting around at Repairs-Shops and handing over money and not being able to decide if I'll buy a new Phone and what-not so I'll just do it all myself and hope I'll be able to and that it all works out well!

So, I need a new Screen, a new Battery, and Tools to insert new Screen and new Battery. Jaysus I really should just go and buy a new Phone shouldn't I!
