Will quarks (specs: 0.9-4.2 volts) go if I run them with 4.5 volts?
The reason I ask is that I have a little headlamp project where a quark head will be run with 3*nimh batteries. They won't fully approach 4.5 volts, but close to that when fully charged. Also, it could happen that someone would want to run it with alkaline batteries... (oh, the horror).
Now I know it won't take long time before 3 nimh batteries (or 3 alkalines, for that matter) are down to 4.2 volts, at least when you draw any significant current from them. But still: Am I likely to destroy anything if I exceed the specs by 0.3 volts?
I would be surprised if I would do anything wrong - particular since the quarks have a buck/boost circuit. But I would still like the advice of CPF experts on this before I try it.
