Capacity test of lead-acid battery

The standard way is to test a battery is to discharge it at the rated discharge rate, if it''s a 20 hour rate that that''s it, unfortunately. Industrial lead acid has a 6 hour rating so it makes my job a lot easier than yours. ... 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 ...
