Apple Macbook Air Replacement Battery A1245

Hello,

I recently bought an original replacement A1245 battery for my old Macbook Air. The problem is that the new A1245 battery is 7.2V 40Wh compared with the old one (which I removed from the laptop) which is 7.2V 37Wh.

Is it possible to use new battery to this macbook safely or this difference in Wh may cause any problem to the device or any danger while charging?
