1 Ah = 1 amp delivered for 1 hour Example: A 12V 100Ah battery can theoretically provide: Note: This is the ideal theory. Real-world capacity is affected by several factors. Proper calculation considering these factors ensures you don't underestimate the battery size you actually need.
To calculate how much energy a battery holds in watt-hours, use: If your battery capacity is in mAh (milliamps), convert it to Ah first: You have a 12V battery rated at 100Ah. So it stores 1200 watt-hours of energy. If you're powering a 100-watt device:
For example, with a battery capacity of 100Ah and a load of 50W, assuming a standard 12V battery, the calculation is: Runtime = 100Ah × 12V / 50W = 24 hours Alternative formulas may include efficiency factors to account for battery discharge characteristics, but the basic formula remains a reliable estimate for most applications.
Battery capacity tells you how much energy a battery can store and deliver over time. It's usually expressed in: To calculate how much energy a battery holds in watt-hours, use: If your battery capacity is in mAh (milliamps), convert it to Ah first: You have a 12V battery rated at 100Ah. So it stores 1200 watt-hours of energy.
