The following table shows how to interpret the leisure battery voltage dis-
played at the display panel correctly.
These values apply to actual operation, not off-load voltage.

If voltage does not exceed this range for several hours.
Measuring the off-load voltage is a simple and effective method of checking
the condition of the battery. Off-load voltage is the voltage of the charged
battery in a passive state, with no current being supplied or drawn.
Take the measurement several hours after the last charging. In the mean-
time, no significant load should have been placed on the battery, which
means no current should have been drawn from it. If the off-load voltage of
the battery is less than 12.0 V, there is a risk of total discharge.
The following table shows how to interpret the displayed off-load voltage cor-
rectly. These values apply for gel batteries.
