Charge controllers prevent your batteries from being overcharged by limiting the amount and rate of charge to your batteries. They also prevent battery drainage by shutting down the system if stored power falls below 50 percent capacity and charge the batteries at the correct voltage level. This helps preserve the life and health of the batteries.
DoD vs. Battery Capacity: Unraveling the Relationship. The battery capacity represents the total energy a battery can store when fully charged.
