12v system with new charger

Finally finished rewiring 12 volt system on my caravan and installed a new "Supercrap"(as some of you refer to them as) 20 amp multi stage charger.plugged the 240v in and charged 120a/h battery to full capacity( strange as already thought was there off my old charger). Turned off power 8.30pm and went to bed.
On way to work at 7.30am turned power back on and checked charger and to my happiness was only charging at absorption rate. Had wife check it at 10.30am and was already on float rate. Sheer bliss for me. Means now that should only have to run generator max of 3 - 4 hrs twice a day now, instead of 12 - 13 hrs per day.

Maybe even get away with running generator say 4 - 5 hrs once a day, does that sound about right??

Forgot to mention was just running Waeco 110 ltr 12 upright fridge which allegedly draws on average around 3a/hrs. Note on this occassion fridge was on from hot. I run LED lights with alleged drain of 0.23a/hrs.
