The fundamental approach involves understanding the nominal voltage and capacity of the battery. The formula for lead-acid battery kWh is: markdown kWh = Voltage x Capacity (in Ah) It’s crucial to consider the efficiency factor when calculating to enhance accuracy.
When using lead-acid batteries it's best to minimize the number of parallel strings to 3 or less to maximize life-span. This is why you see low voltage lead acid batteries; it allows you to pack more energy storage into a single string without going over 12/24/48 volts.
The amount of Power (in Watts) that a 100Ah battery produces depends on what the load requires. A 12V-100Ah battery running a DC (Direct Current) load that demands 50 Amps of current (@ 12 Volts), will produce 600 Watts of power. Power (Watts) = Current (Amps) x Voltage (Volts) Power (Watts) = 50 Amps x 12 Volts Power (Watts) = 600 Watts
This optimal percentage of capacity that you can use is referred to as the Depth Of Discharge (or DOD for short). For example, a Lead-Acid battery that’s usually fully discharged will only last about 150-200 charge/discharge cycles before its rated capacity drops by about 30-40%.
kWh (kiloWatt-hour) or Wh (Watt-hour) is the unit that measures Electrical Energy. A 12V-100Ah battery can store 1200Wh or 1.2kWh of energy, and therefore could be said to have 1.2kWh of energy capacity. If the 100Ah battery is rated at 24 Volts, such as this Ampere-Time battery, it can store 2400Wh or 2.4kWh of energy.
Now, almost all batteries have a 12V output voltage. It doesn’t matter if you have a 100Ah lithium battery, 100Ah deep-cycle battery, or 100Ah LiFePO4 battery; all of them run on 12 volts or 12V. With these two key metrics – 100Ah and 12V – we can precisely calculate how much electrical capacity (measured in Wh) a 100Ah battery actually has.
