Ni-Mh batteries are 1.2 V and Ni-Zn 1.6V

Many of the devices that operate on 1.5V batteries seem to just make it on 1.2V

Is it safe to assume that they will be also OK on higher voltage?

What worries me is that 4 batteries that are effectively re-charged to 1.8V give 7.2V instead of required 6.0V

Quite a difference

I build and play with R/C electric aircraft. When I build a plane, it is quite necessary that I "match" the components. When I choose a battery and a speed control, I have to make sure to get a speed control, which is rated IN EXCESS of the battery's rated peak voltage and current or run the risk of a very expensive airplane flying off to parts unknown!

Your question is along these same lines. I think what you'll have to do is take a look at whatever application you intend putting your battery into. If the battery's potential is greater than the motor or other application can handle, that's where you'll get into trouble.

In my line of toys, a motor, battery, speed control, receiver and servos can cost upwards of $200 sometimes, so a little care down on the ground before you toss your baby into the air is essential.

Hope this helps you on your quest.
