Figure 91 Equalize time period screen

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.

Figure 92 Equalize voltage screen

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.
