The Lead Acid, Lithium & LiFePO4 Battery Run Time Calculator uses these four factors— battery capacity, voltage, efficiency, and load power—to estimate how long a battery will last under a specific load. Here’s why each factor is essential: Battery Capacity: Determines the total energy available for the load.
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.
Although in practice, this seldom is the case. We use the formula: (10 x battery capacity in amp hours) divided by (appliance load in watts). This information appears on the lead acid battery label and in the small print on the appliance.
Using our formula the calculation is [ (10 X 60) ÷ 100] = 6 hours maximum run time. We recommend recharging after four hours in these particular circumstances. Since running a lead acid battery flat is bad for its health, and reduces future run time. Try to prevent a battery discharging completely. The maximum discharge depends on the battery type.
Last example, a lead acid battery with a C10 (or C/10) rated capacity of 3000 Ah should be charge or discharge in 10 hours with a current charge or discharge of 300 A. C-rate is an important data for a battery because for most of batteries the energy stored or available depends on the speed of the charge or discharge current.
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
