In response to Captain Ron's thread, here is my experience with lead acid batteries;
Our 795, based in Marmaris, Mediterranean has two lead acid house batteries (2x105), one crank lead acid battery (1x110), one lead acid bow thruster battery 1x60 amp. All are Varta brand. Two victron solar panels 2x175, one victron smart solar charger 100/30. This set up is from 2022 season. The previous factory standard setup of one house battery lasted a little over 2 years particularly in our case without solar power support. The crank battery was good, but had to replace it with a new one to keep house and crank as a set. The bow thruster battery was also good and we chose to keep it.
Up to now, knock on wood, I have no battery issues. I can leave the boat at the marina for extended periods, without shore power, all switches off and find the batteries full. Longest stay at sea was three nights. Small Pure sinewave Victron Phoenix 500 watt inverter gives enough power to support the basics like TV, air cooler etc. plus a small vacum cleaner and a Turkish coffee machine alternately.
