First I thought that I'm going to buy that official Samsung battery but then I discovered those extended batteries. So I tried to find that ZeroLemon 7500mAh but there were no batteries available nor the double pack of 3000mAh batteries incl. the charger which is a option too. So I found some other batteries but I'm not sure are they any good. Also if someone has that ZeroLemon battery (7500 or the 2x 3000) could you tell where you bought it and when? Maybe you can make some kind of list of available extended batteries for Samsung Galaxy S4? I don't understand why they made the S4 batteries only after year it was released and stopped making them so soon.
Sadly you can't find ZeroLemon for S4's anymore. They stopped making them officially over 2-3 years ago and what was kicking around on the market was the last of the stuff. The last I saw was in early 2017 for £10 and like an idiot I didn't buy it not realizing it was end of life stock clearance. Never saw any again. Not even on Ebay.
Note: Any other battery that says it is 3000mah is a FAKE. The only one company that managed this was ZeroLemon and Anker both of whom no longer produce these batteries. The ones on Amazon are confirmed fake, just read the customer comments.
I ended up buying a PowerBear extended battery from amazon. It was a 6000Mah one and works a charm. I believe a few battery cases from Dophie are now selling for under $20 on Amazon as stock clearance. Grab em while you can!
