Using 7.4V battery in my camera when the original was 7.2V?

I have a handful of Nikon cameras lying around here. My newest camera has a rechargeable Lithium ion battery that says the following:
7.2V 1230mAh 8.9 WH
In some of the older models I have a battery of the same dimensions that states:
7.4V 1030mAh 7.7 Wh

I tried out of curiosity to put the second battery into a camera that used the first that I listed. The camera turned on and worked fine. I am wondering if I switch the batteries out will I be damaging the electronics.

How about my metering? Do I set it to Matrix, Center-Weighted, or Spot given that my subject is in the dead center and in a non-studio background?
