FAQs about Battery discharge current from positive to negative
Does current flow in a battery move from positive to negative?
No, current flow in a battery does not move from positive to negative. Instead, the flow of electric current is conventionally described as moving from the positive terminal to the negative terminal. Electric current is defined as the flow of electric charge.
What happens when a battery is discharged?
During the discharge of a battery, the current in the circuit flows from the positive to the negative electrode.

What happens when a battery is discharged deep?
When a battery undergoes deep discharge, several critical changes occur: Voltage Drop: As the battery discharges, its voltage decreases. Each battery type has a specific cut-off voltage where it ceases to function effectively. For example, lead-acid batteries typically should be discharged at 10.5 volts.
How do I specify the charging/discharge rate?
The charging/discharge rate may be specified directly by giving the current - for example, a battery may be charged/discharged at 10 A. However, it is more common to specify the charging/discharging rate by determining the amount of time it takes to fully discharge the battery.
Should a battery be fully discharged before charging?
For example, nickel cadmium batteries should be nearly completely discharged before charging, while lead acid batteries should never be fully discharged. Furthermore, the voltage and current during the charge cycle will be different for each type of battery.

What is the reason for the full solar charging voltage
For lead-acid batteries, the initial bulk charging stage delivers the maximum allowable current into the solar battery to bring it up to a state of charge of approximately 80 to 90%. During bulk charging for solar, the battery's voltage increases to about 14.5 volts for a nominal 12-volt battery. When Bulk Charging is complete and the battery is about 80% to 90% charged, absorption charging is applied. During Absorption Charging, constant-voltage regulation is applied but the current is reduced as the solar. Float charging, sometimes referred to as “trickle” charging occurs after Absorption Charging when the battery has about 98% state of charge. Then, the charging current is reduced further so the battery voltage drops down to the Float. For flooded open vent batteries, an Equalization charge is applied once every 2 to 4 weeks to maintain consistent specific gravities among individual battery cells. The more deeply a battery is discharged on a daily.
