50% Depth of Discharge for Lead Acid Battery

"Lead acid batteries should be discharged only by 50% to increase its life" – is an oft used phrase. This means that we should cycle them in the 100% to 50% window as shown below in the Typical state of charge window parameter. So it follows that the usable capacity of a lead acid battery is only 50% of the rated capacity.
