The discharge characteristics of the lead-acid battery group, the battery at a certain ambient temperature (25 ¡ã C in the figure), the relationship between the battery-end voltage and the discharge time is referred to as discharge curve, lead-acid battery depending on the discharge current. The curve is different, and the discharge curve can be seen as follows:Lead and discharge characteristic curve of lead-acid battery pack (1 # group)
