Originally posted by zvon it states in the manual that you should not use batteries above 1.5v. such as oxyride which put out 1.7 volts as it may damage the camera.
But 1.7V is the output of an empty battery as is the case with rechargeable (1.2 when empty) and alkalines (1.5 when empty)... I never owned oxyride batteries but I would guess that when fully fresh they should give up to 2V which if you multiply by 4 is 8, and standard Li-ion for k-r is 8.3 when fully charged. So I dont get the logic that oxyride would damage the camera.. I used a simple multimeter for voltages i mentioned above.
Here's my take on it, your mileage may vary.
I follow the manufacturers specs/recs when using a high priced electronic device. Does that mean I only use OEM equipment, no. What it does mean is that I follow the specs. So, if they say that Zinc batteries are not appropriate or that above 1.5v is not supported, I just don't use those items. Math is a funny thing. We all think we can do it and get the right answer, the problem is that we often don't know ALL the #'s involved in the equation and so in our simplification of the equation believe we have an answer that contradicts the manufacturer. We then act on that faulty conclusion thereby putting our equipment at risk. Batteries that are <1.5v are plentiful, cheap, and reliable. Stick with them.
