Deep cycle batteries are in practice, either used as single batteries at desired amp-hour (Ah) ratings or a parallel connection of a number of lower amp-hour rated ones to achieve the desired amp-hour rating. This works presents an experimental determination of the runtime performance of a single 12V, 200Ah deep cycle battery and two (2) 12V, 100Ah batteries connected in parallel to achieve 12V, 200Ah rating. The single 12V, 200Ah deep cycle battery and two (2) 12V, 100Ah batteries connected in parallel were loaded separately using the same inverter and the same load and the rate at which they discharged was tracked. Analysis of the performance showed that the single 12V, 200Ah battery exhibited a longer runtime under the same load condition, than the parallel connection of two 12V, 100Ah batteries.
