Battery Capacity: A Guide to Understanding
Let''s say you have a 100Ah 12V battery and you want to learn how many Wh hours it has. 100Ah x 12V = 1200Wh/ 1.2kWh; Keep in mind though, that just because two batteries have the same charge capacity (Ah) it does not mean they will necessarily have the same energy capacity. For example: 100Ah 12V battery = 1200Wh; 100Ah 24V battery = 2400Wh
