The capacity of a lead–acid battery is not a fixed quantity but varies according to how quickly it is discharged. The empirical relationship between discharge rate and capacity is known as Peukert''s law.

Lead Acid Batteries

Lead acid batteries are the most commonly used type of battery in photovoltaic systems. Although lead acid batteries have a low energy density, only moderate efficiency and high maintenance requirements, they also have a long lifetime and low costs compared to other battery types.

How to Measure Battery Capacity

Lead-Acid Batteries. Lead-acid batteries are commonly used in automotive applications and as backup power sources. To calculate the capacity of a lead-acid battery, you need to know its reserve capacity (RC) and voltage. The reserve capacity is the number of minutes a fully charged battery can deliver a constant current of 25 amps at 80°F

What is mAh/g Specific capacity?

The unit mA-h/g means milliampere-hours per gram mass. However, since mA-h means milliampere-hours, that is, providing a stated current for a stated time, it cannot be compared with watts, a unit of power paring mA-h and W is like comparing apples and barium. An automobile lead-acid battery might be rated 12 V at 60,000 mA-h (60 A-h),
