From what I have gathered on the internet, it doesn't turn off. When running it displays RPM, when engine off, displays run time. Estimate for the internal battery was 10 years, but I wouldn't bet on it. This is a sealed unit and priced low enough that after a few years it is a throw away. Liquid Crystal displays use very little power, micro micro amps, and it is possible that it is designed to charge itself when the engine is running off the pulses from the plug wire, micro amps at a time. All that said, I don't think you have a problem, just need to read the instructions and see if they say anything different, I couldn't find them online so hope you have them.

What kind of inverter is it and what kind of meter are you using to check the voltage with? If the inverter puts out modified sine wave, you have to use a true rms volt meter to accurately check the voltage with. A non rms volt meter will show a low reading.

The rms voltage is what counts, because it tells how much power the output will deliver to a resistive load. Inexpensive multimeters on their AC ranges are usually average-responding rms-calibrated meters. This means they measure the average of the absolute value of the AC component of the signal, and display that average multiplied by about 1.11 (actually, pi over sqrt(8)), the ratio of rms to average value for a pure sine wave. That way, the meter will give the right rms reading for a sine wave.

If the signal is a square wave, where the average and rms values are equal, the average-responding meter will read 11% too high.

Many inverters put out a modified sine wave (MSW), which sits at zero for a while, goes to a constant positive level for a while, goes back to zero for a while, and goes to a constant negative level for a while to complete the cycle. The positive and negative parts of the signal have the same magnitude and duration.

The rms and average values of an MSW depend on its duty cycle D, the fraction of a cycle for which the signal is not at zero. In a well-designed inverter, the duty cycle will be adjusted when the DC input voltage goes up and down to maintain the nominal rms output voltage. If we use peak voltage Vp to mean the magnitude of the positive and negative voltages the signal goes to, then Vavg for an MSW is equal to Vp times D, and Vrms is equal to Vp times the square root of D.

The duty cycle for which an MSW will have the same rms to average ratio as a sine wave is 8 over pi squared, or 81%. For any duty cycle less than this, an average-responding meter will read a lower voltage than the inverter rms output, and for a duty cycle higher than this, the meter will read too high.

If your MSW inverter is putting out 120 volts rms and its duty cycle varies from 50% to 75%, the meter reading will vary from 94 volts to 115 volts. I avoid the problem by using a Radio Shack 22-174B true rms digital multimeter.

96 volts is low. 106 volts is low. You need to be about 110 to 120 volts optimum. How is your battery input? This is crucial for the inverter to output correctly. If it needs 24 volts DC in Then make sure it's 24 volts. 48 volts means 48 volts. Check the battery voltage and compare to inverter input requirements first.
