While you are at it there is a good question and sorta an answer to Amp Hours and battery charging in the September Trailer Life.
They basically said to never let the battery capacity drop below 50% and to treat the battery as if it had only half the available amp hours.
Also stated to never charge faster than 20% of the discharged amp hours.
