Reasons for the high internal resistance of colloidal batteries
Battery Internal Resistance
Low internal resistance batteries are much better at supplying high current pulses. Internal resistance also increases as the battery discharges. Therefore, a typical alkaline AA battery may start out with an internal resistance of 0.15Ω but may increase to 0.75Ω when 90 percent discharged.
