I don't understand victronenergy's adaptive algorithm well. Victronenergy says that the absorption time should be longer with a very discharged battery and shorter with a slightly discharged battery. But why? whatever the previous discharge, when the battery reaches the absorption voltage, eg 14.4v, it means that it is at 80% charged. Case 1: 100 Ah 0% battery, charged with 10 A charger. After 8 hours of bulk, it will be around 80%. And the absorption begins. Case 2: 100 Ah 60% battery, charged with 10 A charger. After 2 hours of bulk it will be about 80%, so as in case 1. And absorption begins. Why, according to the victronenergy algorithm, must the absorption of case 1 last 8 hours, while the absorption of case 2 must last 2 hours? Why,if both batteries are about 80% charged when absorption starts? According to electrical physics, providing a constant current of 10 amperes, any battery, at any level of discharge, will have the same level of charge when the absorption voltage is reached. That is about 80%.
