Anker 2600mah battery

[Tweakforce_LG]

So I want to order this battery for an s4 that I repaired and got for free with a old drained battery. I'm ordering this to avoid cheap Chinese knock offs that are overpriced locally.

Is this a good replacment battery since I want to use this phone for 2 years (by then it will be mid low end)

I have a good memory with Anker customer services. Yes, I think it would be nicer than generic ones.

Couldn't ship to NZ so I brought an original battery from the Samsung autherised repair centre.
