How Is AH Calculated for Different Battery Types?
AH, or ampere-hour, is calculated differently for various battery types based on their capacity to store and deliver energy. The formula for calculating AH is straightforward: multiply the current (in amperes) by the time (in hours) the current is drawn.
For lead-acid batteries, AH is typically specified by the manufacturer. These batteries discharge at a relatively constant current until they reach a specific voltage. To calculate their AH, one must use the discharge rate and time. For instance, a 100 AH battery could theoretically provide 100 amps for one hour or 10 amps for ten hours.
Lithium-ion batteries also follow the same principle. Their capacity is often stated in AH. However, they can maintain a higher discharge rate without the same voltage drop seen in lead-acid batteries. This means they may perform better under load, providing more power over a shorter time.
Nickel-cadmium batteries can also be calculated using the same formula. They have a characteristic called the Peukert effect, which suggests that the capacity decreases at higher discharge rates. This means their effective AH might be less than rated if drawn at a high current.
In summary, to calculate AH for lead-acid, lithium-ion, and nickel-cadmium batteries, multiply the discharge current by the time of discharge. This approach allows for understanding how much energy each battery type can reliably provide under different conditions.
