Battery A1496 for a1466

Hi! I got a macbook air a1466 mid 12 and unfortunately my battery died.. I bought a new one from a seller but instead of a1405 he brought me an a1496 battery type. I asked the seller for replacement but he said that the new one will work even better for my laptop. I had to check if that's right.

The a1496 fits on it, but the wired thing is the voltage. The a1405 is 7.3v and the a1496 is 7.6v.

I'm really confused here, hope you can help me out (:
