Advice on installing new battery

[mrskullfreak]

I have searched the forum and seen nothing.
Am looking to replace iPhone 6 battery.
Wondering where to buy one and I will need the special tools for it also.
Any help would be great.

Amazon or Ebay would be the best bet. The battery may or may not come with the proper tools.

iFixit explains the procedure well. Be sure to read all comments.
