Trying to determine what size bank I need ...
If a battery is rated at, say, 100 Ah reserve capacity, does that mean 100 Ah in total? In other words, does it mean the battery actually has only 50 Ah you can actually USE, before reaching the critical 50% level? Or does it mean there are 100 Ah available for daily use?
Sorry for the rookie question. I'm reading Don Casey's "Sailboat Electrics Simplified", but have not yet come to this answer. Plus I'm a slow learner.
