Question about the battery in my s5 G900V

can i replace the stock battery with a battery that is 3.8 volts instead of 3.85 volts like my stock battery or could it break the phone/cause damage also is it unwise to buy the battery from ebay? wanted to post the link but cant :(

also it says the battery is for the Samsung Galaxy S5 SV i9600 but i believe it will still work for mine.
