Formula: Lead acid Battery life = (Battery capacity Wh × (85%) × inverter efficiency (90%), if running AC load) ÷ (Output load in watts). Let’s suppose, why non of the above methods are 100% accurate? I won't go in-depth about the discharging mechanism of a lead-acid battery.
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
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.
Our tool has many uses — whether you want to know how much longer your drone will fly after already using it for a few hours, or if you want to compare lead-acid and lithium-ion batteries in terms of their battery capacity, the battery size calculator does it all! How do I calculate the discharging time of a battery?
An ideal (theoretical) battery has a Peukert exponent of 1.00 and has a fixed capacity regardless of the size of the discharge current. The default setting in the battery monitor for the Peukert exponent is 1.25. This is an acceptable average value for most lead acid batteries. Peukert’s equation is stated below:
The battery size calculator calculates the battery size in ampere-hour (Ah). Load (ampere or watt): Specify the load value, and select the load unit. For example, 100 Watt. Or 10 A. Use an average value if it is a cyclical load. Voltage (Vdc): Specify the battery voltage in volts DC, if the load type is watt.
