   - a simple [[electrical:​solar:​charge_controller#​shunt|shunt charge controller]] holds the battery at a mild Absorption voltage (14.0, - 14.2v, see notes [[electrical:​solar:​shallow_cycling#​charging_voltages_and_starter_batteries|below]]) when charging, just below the significant gassing point   - a simple [[electrical:​solar:​charge_controller#​shunt|shunt charge controller]] holds the battery at a mild Absorption voltage (14.0, - 14.2v, see notes [[electrical:​solar:​shallow_cycling#​charging_voltages_and_starter_batteries|below]]) when charging, just below the significant gassing point
