DATA: YOUR BATTERY HISTORY

DATA: The DATA mode is used to recall key historical information about the battery.

To access the DATA displays:

Before you begin, select the battery whose data you wish to see.

1)Hold down the SET button until SEL appears in the numeric display.

2)Press the SEL button six times until the red light above the word DATA appears.

3)Charging Efficiency Factor is the first number displayed.

4)Press SEL again. The number of CEF Recalculations is displayed.

5)Press SEL again. The deepest depth of discharge is displayed.

6)Press SEL again. The average depth of discharge is displayed.

7)Press SEL again. The next light on the Light Bar, the one over the word LOCK will come on. The LOCK function is described on the next page.

What the Historical Information Means:

CEF (Displayed as E99): The Charging Efficiency Factor (CEF) is the rate at which amp hours are counted back up during charging. The amp-hour CEF, not kilowatt-hour CEF, isdisplayed.A displayofE99 indicatesa99%CEFbasedonamphours.The Defaultsetting is 95%. NOTE: If the CEF display has a "u" in front of it, this means the CEF has been selected by the user. See Advanced Function F06 on page 18 for details.

#CEF Recalculations (Displayed as +I999): This is the number of times that the battery has been discharged more than 10% and then completely recharged (meaning charged until theChargedParametershavebeenmet).Considerthistobe thenumberofcharge/discharge cycles the meter has recorded since its last RESET to factory defaults. A discharge of less than 10% of battery capacity is not counted as a "cycle."

Deepest Discharge (Displayed as -i999): Shows the deepest discharge in amp hours recorded by the meter since its last RESET to factory defaults. Think of this as the "worst thing you've ever done to your battery."

Average Discharge (Displayed as i999): The running average of all discharges since RESET to factory defaults. For best battery life, you should not routinely discharge more than 50–65% of your battery's capacity. If you do, you shorten its life. An average discharge of 500 amp hours on a 900 Ah battery is demanding but not unreasonable. An average discharge of 180 amp hours from a 200 Ah battery is almost a sure way to make a battery 23 salesman happy!
