MAX 72

When the battery is at full voltage (not being recharged), this selection reads EQUALIZE TIME PERIOD (hrs). When the battery is recharging, this selection reads EQUALIZE TIME REMAINING (hrs). After the equalize recharge time has expired, the indication returns to the preset equalize time.

The equalize voltage is also programmable. In the example above, the range is 520 to 580 volts with the default being 540 volts.

Battery Temperature Compensation Charge

The Battery Temperature Compensation Charge screen is accessed from the Battery Management Screen (Figure 83). The Operator can enable or disable Battery Temp Compensation function. He can also change the compensation setting by going into the edit screen. The values are in millivolts/ degree C.
