In the early 1970's I served for a time on one of the government lighthouse supply ships. At that time some of the remote lighthouses were battery powered. We would replace these batteries (no solar charging then) about once a year. This involved carrying heavy "Edison" cells in special back packs up to the light. These big black batteries were around 2v and weighed plenty. I reckon they would have been around 420 amp hour rating - but its all so long ago.
