Run time - Amount of time it takes to discharge the cell to the discharge cutoff voltage. Run time is important, as it tells you how long the cell will last when discharged at the discharge current to the discharge cutoff voltage.  NOTE: Make sure when comparing cells to different battery matching companies, that they use the same discharge rate.  The Run Time on a pack discharged at 35 amps will be lower that the Run Time on a pack discharged at 30 amps. 

Charge rate - Amperage rate the cell is charged at. Please see our charging instructions for recommended charge rates.

Discharge rate - Amperage load used to discharge the cell.

Discharge cutoff voltage - Voltage level used to stop the voltage averaging. The discharge cutoff voltage we use is 1.0 volts. This is the voltage level at which the average voltage reading stops.

Average voltage - The average voltage level throughout the discharge process. The average voltage is calculated by sampling the voltage 10 times per second, starting at the peak voltage and terminating the sampling when either the discharge cutoff voltage is reached, or when the discharge time has expired. It is possible to 'fudge' the average voltage by setting the **discharge cutoff time to be lower than the time it takes the cell to discharge to the cutoff voltage. For example... if a cell takes 460 seconds to discharge to 1.0 volts (the cutoff voltage) then it is safe to assume that as long as the discharge cutoff time is set to be at least 460 seconds, the average voltage calculation will be correct. But what happens if the discharge cutoff time is set to 400 seconds? Well, the answer is simple... the average voltage will be calculated only for the first 400 seconds of the discharge time, resulting in an average voltage reading that is much higher than it would be if calculated for the full discharge. Pro-Match always sets the discharge time to 5000 seconds, so that the average voltage reading will be over the entire discharge time! Beware of matchers that change this value or do not print this number on their labels at all! The higher the average voltage, the faster top speed your motor will have. Higher Average voltage is most important to people who race in stock classes.

Actual resistance - The resistance of the cell's internal structure. A cell's internal resistance is a key factor in the amount of "punch" it can provide. The lower the internal resistance (AR), the quicker the energy can be released from a cell, giving you more "bottom end" power. This number is most important on high grip tracks where maximum acceleration is needed.

Discharge cutoff time - Number of seconds before terminating the average voltage calculation. Make sure this number is on the cell and set to 5000 (default setting on TM4 and TM8 matchers)
