How fast should a lead acid battery be discharged?

The faster you discharge a lead acid battery the less energy you get (C-rating) Recommended discharge rate (C-rating) for lead acid batteries is between 0.2C (5h) to 0.05C (20h). Look at the manufacturer’s specs sheet to be sure. Formula to calculate the c-rating: C-rating (hour) = 1 ÷ C

How to make a lead acid battery?

How does a lead acid battery discharge?

The next phase of discharging is in the bulk or main part of the discharge. During this phase, most of the energy of the battery is discharged. For a lead acid battery, this happens in a relatively linear manner, with the voltage dropping in proportion to the Depth of Discharge, or inversely proportional to the State of Charge.

How many Ah can a lead acid battery deliver?

A lead acid battery is rated at 100Ah at C20, this means that this battery can deliver a total current of 100A over 20 hours at a rate of 5A per hour. C20 = 100Ah (5 x 20 = 100). When the same 100Ah battery is discharged completely in two hours, its capacity is greatly reduced. Because of the higher rate of discharge, it may only give C2 = 56Ah.
