Amp hours quantify a battery’s energy storage capacity by measuring current delivery over time. A 20Ah battery can supply 20 amps for 1 hour or 2 amps for 10 hours. This metric is crucial for comparing batteries in solar systems, EVs, and portable electronics, though real-world performance varies with load demands and environmental conditions.
Watt hours (Wh) = Amp hours (Ah) × Voltage (V). This conversion reveals total energy storage. A 12V 100Ah battery stores 1,200Wh. This calculation helps compare batteries with different voltages, like lithium-ion (3.7V/cell) versus lead-acid (12V).
So, a 12V 20 Ah battery would have a total energy capacity of: 12V×20Ah=240Wh12V \times 20Ah = 240 Wh This means the battery can deliver 240 watts for one hour, or any equivalent combination of watts and time (e.g., 120 watts for 2 hours).
A 12V 20Ah lithium battery has a theoretical capacity of 240 watt-hours (Wh) and its runtime depends on the device’s power consumption. For example, at a constant 20-amp load, it will last about one hour, whereas at a 10-amp load, runtime extends to roughly two hours. These batteries typically last over 3,000 cycles, equating to 8–10 years of use.
