A 20 amp hour (Ah) battery denotes a battery’s capacity to deliver a continuous current of 20 amps for one hour, or alternatively, a lower current for a proportionally longer period.
Knowing the distinctions between battery amp hours, ohms, volts, and watt-hours is essential for understanding how batteries work and how electricity behaves in circuits. Amp-hours (Ah) Amp hours represent the capacity of a battery to store electric charge. It indicates how much charge a battery can deliver over time.
Batteries are about storing energy. An amp hour rating shows how much current a battery can deliver over a set period. If you have a higher amp-hour battery, it generally lasts longer. For example, a 50Ah battery can deliver 50 amps for 1 hour, or 1 amp for 50 hours, depending on usage. Amps (A): Amps measure electrical current.
For example, a battery with a rating of 100 Ah can deliver a current of 1 amp for 100 hours, or 5 amps for 20 hours. It’s important to note that the actual capacity of a battery can vary depending on factors such as temperature and discharge rate. Higher discharge rates can reduce the overall capacity of the battery.
For example, if a battery has a rating of 10 Ah, it can deliver a current of 1 amp for 10 hours or 2 amps for 5 hours. However, it’s worth noting that the actual capacity of a battery may vary depending on various factors, such as temperature and load conditions.
In practical terms, a 20Ah battery could sustain 20 amps of current for 1 hour, 10 amps for 2 hours, or 1 amp for 20 hours.
