[Q] Battery question . topic

Hi guys
I want to change my galaxy s4 I9505's battery .
I found a great deal to buy a 2600 original samsung battery BUT , the problem is that :
All the notes on the battery are the same as mine beside this :

11,78 Wh - new battery
9,88 Wh - my battery .
--------------------------
Charge voltage limiting 4,35V - new battery
Charge voltage limiting 3,8V - my battery .


Will it work with these things different from my battery ?
What does 11,78 Wh mean ?


Thanks alot ! ^^
