Capacitor pastes for flooded deep discharge lead-acid batteries include lead oxide, a carbon additive, and an aqueous acid. The capacitor paste contains lead and carbon in a lead to carbon mass ratio of about 5:1 to 82:1. Hybrid negative plates for flooded deep discharge lead-acid batteries can be made using such pastes in combination with traditional pastes. The hybrid negative plates include a capacitor paste on a bottom portion of the plate, and a traditional paste on the remainder of the plate. Batteries using the capacitor paste and hybrid plates exhibit improved performance over batteries with conventional plates and pastes and require less overcharge to prevent electrolyte stratification.
