For what it''s worth, lead acid capacity is not easy to predict. This is key: The capacity of a lead acid battery depends on the load. A new 100 Ah battery at 20H would give you indeed 5A for 20 hours (60Watt). But this is the kicker: If your actual load on the battery is 120 Watt or 10A you won''t get 10 hours.
