Make sure the mode is correct for either Gel/AGM or flooded/standard.
Example BCI Group 35 battery is 45-60Ah and 12.3V is roughly 60% state-of-charge, so at least 14hrs to fully charge.

It should climb up to 14.4V before backing down to float. I think the display backlight is red until it thinks it's charged the battery, then it goes green.
