Can the unit handle short period inrush current over 100A? And why not allow remote reset button?

Yes. It won't damage the meter with the short period current over 100A.

How long is the shorter CT cable? Only the length of the longer cable is listed.

The length of the short CT cable is 5.9inch(15cm).

I see how you can zero the current measurement, but my voltage measurement is off by a full 0.5V. How is the voltage measurement calibrated?

Please follow the instructions below to reset the voltage value to factory setting and it should solve the prolem. If not, please click the link of "ask seller" in your order details to get a replacement. How to reset the voltage value to factory setting: Press and hold the back button for 6 seconds then release the button. And it will display "5HH" on the screen.

does this work with lead acid and lithium batteries ?

You can measure any DC 5~100V 100A power source with this meter no matter what type of your battery.
