Charging queries (again) (1 Viewer)

[sylvester1954]

Sorry if this has been discussed before but advice is very welcome. The control panel (EC480) on my van has been on hook up for charging for several hours yesterday evening. Capacity read 100%,leisure and vehicle around 13v each.
After a 100 trip today we are parked up for the evening in a secluded location since 6pm and we are only using a couple of interior lights. Nearly 11pm and both leasure and vehicle readings are down to 12.4 and capacity still 98%.
My question, is that reduction to 12.4 'normal' in the time given, or should I be looking to find why it has reduced so much already. Slightly mithered here as I truly understand what is the norm.

For state of charge battery voltage is measured off load.
12.4 v is Approx 75% off load, if you have only two led lights on it will probably read 0.1-0.2 v less than the off load voltage.
I assume you are reading your control panel I would check the voltage with a multimeter as one of your readings does not sound right, either the volts are reading low or the power is reading high.
