The optimum charging cauurent for a battery is around 10% of it's capacity which should therefore get it up to around 80% charge in about 8-10 hours from flat. The last 20% takes a lot longer, possibly another 8-10 hours mainly because the charging current tails off as the charger is voltage limited and frequently switches down to around 13. 8 volts when the charging current drops below a certain level. Some chargers will hold the higher 14. 4 volts for a timed period after the threshold to try and get the last bit in a bit faster - ideally you need to monitor both voltage & current to establish what is going on. Specifically designed to cater for cars with start/stop systems, the CTEK CT5 helps to maintain your battery if your car has to sit for a little while.

I'm now used to seeing a voltage around what you report, regularly on my in car voltmeter. I'm told that anything over 12 volts should be enough to turn and start the car, which appears to be true. A modern Aldi/Lidl smart charger, with 3. 6-4. 0 Ah rating should be capable of recharging from absolutely flat to 90+% fully charged in around 24 hours but may take another 24 hours of float charging to show 4 LEDS - at 12. 3v the OP's battery should have got to 90+% in around 15 hours.
