3. DIGITAL DISPLAY OF BATTERY LOAD (white)
- displays the load of the battery
- + or - sign on the left of the lead digit, whether the battery is in overcharge (“+” displayed)
or in discharge (“-” displayed)
- nothing is displayed when the battery is in charge within the expected range
- leading zero is suppressed in the lead digit position
- digital number gives the rate of the load, with 1.00 equal to 100% of load
- examples:
• “+1.30” indicates that the battery is in overcharge at 30% over the maximum rate of
the charge
• “.60” indicates that the battery is in charge at 60% of its maximum rate of charge
• “-0.30 “indicates that the battery is discharging at 30% over the maximum rate of
discharge
4. DIGITAL DISPLAY OF BATTERY TEMPERATURE
- battery temperature digits are displayed in white with a + or - sign on the left of the lead
digit, when the temperature is within normal limits
- when the temperature is in the range (+50°C to +65°C) the digits turn yellow
- when the temperature exceeds 65°C the digits are displayed in red
