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. There is a risk of total
discharge if the off-load voltage of the battery is 12.0V or less.
The following table shows the correct interpretation of the off-load voltage
displayed. The values specified are guidelines for gel batteries.
Values for off-load voltage Charge state of the battery
12V or less discharge or total discharge
12.2V approx. 25%
12.3V approx. 50%
more than 12.8V full
