If the battery is old as the hills 1 percent per day. If it is new 2 percent per week. If it is AGM self discharge rates are less.
The battery is the usual flooded cell, brand new yesterday, charged all night (TT plugged in/on board smart charger) still plugged in until I take it back to the storage yard tonight (24 hrs total charging time).
2 percent per week sounds fairly reasonable. My FLA batteries have been sitting idle for 4 1/2 months and when I went to charge them today they were at 70 percent. Temps have been averaging 35-40F.
