We may only want to discharge the battery 50 percent however, so If we only want to discharge the unit down to 50 percent for extended battery life, and do it in cold whether, then the approximate hours figure is 1.24 hours in cold weather. 70 (the load decrease coeficient) equals 2.48 hours if we discharge the battery 100 percent.

Cold temperatures also reduce capacity, so if you are going to operate this at just at just above freezing at a full 100 percent discharge, take the initial capacity in amp hours of 200 and reduce this by 20 percent equaling 160 amp hours, divide by 45 amps our digger head will draw when operating, which equals 3.55 x. 70 (calculation for decreased capacity of a battery as load increases) equals 1.55 hours. In the above example, if a deep cycle battery recommends only a 50 percent discharge level for good battery life however, then the 200 amp hours in our example becomes 100 amp hours divided by 45 amps power draw, equals 2.22 hours x.This is an estimate and can be different depending upon the quality and capacity of the deep cycle battery (sometimes the gel batteries are the best, but again it depends on the battery). This figure of 3.08 houres, applies specifically to a 200 amp hour battery with approximately a 45 amp draw, and was extrapolated from an actual measurement of the discharge on a 200 amp hour gel battery. 70 (70 percent) which is equal to 3.08 hours. As a simple estimation, take the 4.44 hour rate in our example and multiply it times. The battery capacities are non-linear because the capacity of a battery decreases when the load increases. As calculated above, the MYAUJ307DC digger head on this page draws 45 amps when you operate it, so theoretically it could be operated for 4.4 hours (200 divided by 45 equals 4.44) however this is not case.Some batteries may be rated at a 100 amp hour rate so check the label on the battery before applying the above equation. Conversley if you know (as with the model MYAUJ307DC digger head) that it draws 45 amps, then if you have a 200 amp hour battery (rated at the 20 hour rate), then 200 divided by 45 equals 4.44 hours of run time theoretically. If you have a 200 amp hour battery (rated at the 20 hour rate), then 200 divided by 20 equals 10, meaning you can theoretically draw 10 amps for 20 hours before the battery is fully discharged. You can make an estimation of running time using the amp hours equation which gives you the maximum sustained amperage drawn from a fully charged battery over a certain time period to a point where the battery is 100 percent DOD (depth of discharge - fully discharged).If it is rated less or for further explanation see below. A simple approximation of running time for running this unit off of a stand alone deep cycle marine battery (not being charged in a vehicle), estimate 1.5 to 3 hours maximum if your battery is rated at 200 amp hours.Approximation Of Running Time When Connecting To A 12 Volt Deep Cycle Marine Battery Not Connected To A Vehicle.The draw of the digger head motor is 45 amps constant draw when unit is on. The running time on a battery not being charged by your vehicle varies depending upon the capacity of the battery. If you cannot connect to a running vehicle, it can be used on a fully charged deep cycle battery.
