I was asked an interesting question to which I don’t know the answer:-

Does anyone know what is the lightest weight or smallest lead acid batteries with the highest Ah capacity on the market today?

Flooded batteries usually start at 105 hours capacity for a standard size 31. Weight is 59/60 pounds. and range to 150 hours at 80/82 pounds. All the major battery manufactures are within a fraction of each other for the same size and capacity.
