Are my lead acid batteries not charged well enough

ok. So you can only reasonably used 50% of lead acid cells. If fully charged when most charging stops (say 5pm) then say you have to run 12 hours (5-6am) then that gives you a budget of 1200wh / 12hr = 100w/hour, so 60w for the fridge + lights + a tiny bit more and your have nothing left.

Charging Settings For Lead Acid Batteries: What To Use And Best

To charge a lead acid battery, use a DC voltage of 2.30 volts per cell for float charge and 2.45 volts per cell for fast charge. This is crucial for fully charging the battery without causing damage. For a 12-volt battery, this translates to a total charge voltage between 13.8 and 14.7 volts. After reaching full charge, the battery
