It''s a typical 12 volt lead-acid battery discharge characteristic and it shows the initial drop from about 13 volts to around 12 volts occuring in the first minute of a load being applied. Thereafter, the discharge rate doesn''t unduly affect the output voltage level until the battery gets quite depleted of stored energy.

A car battery is a 12-volt lead-acid system that provides power to the car''s starter and voltage regulator to work together. To start a car, you need to have enough voltage in your battery. Generally, a car needs at least 9 volts of electricity to start, although some with more advanced electrical systems may require up to 11 volts.
As a general rule, the higher the voltage, the more charge the battery has. However, the relationship between voltage and state of charge is not always linear. For example, a fully charged 12-volt lead-acid battery will have a voltage of around 12.8 volts, while a partially discharged battery may have a voltage of 12.2 volts or less.

A 100Ah rating means the battery will be able to power a 5 amp appliance for 20 hours ( 5 x 20 = 100) before the cell voltage drops below 1.75 volts per cell ( 10.5 volts for a 12 volt battery). However it does not mean the battery can power a 50 amp appliance for 2 hours due to Peukert''s Law which states that the faster you discharge a battery, the less capacity it actually

Charging methods for lead acid batteries include constant current
If the SoC voltage implies the battery OCV is 12.5 volts and the charger is putting out 13 volts then the battery has about 10.5 milli ohms and the implied current will be 0.5/0.0105 = 47.6 amps. In other words, using your graph, for a given fixed charging voltage, if the SoC is low, you get more charge current.

The lifespan of a 6V battery depends on several factors, including the battery type (alkaline, rechargeable, lead-acid), the device''s power consumption, and how often the battery is used. Generally, an alkaline 6V battery can last anywhere from 100 to 300 hours, while rechargeable batteries tend to last for hundreds of cycles, providing better long-term value.
