Mark I can't provide technical data but last season I flew a Red Herring to death (over the course of spring, summer and fall) that was equipped with a 555 (caseless) two cs10's, and 2-3volt CR2 camera cells. When I finally took the Herring apart to utalize the gear the batteries were still going strong. Servo torque and speed were way up but no ill effects were noted other than I didn't have to bother to charge. Denny Maize RCSE-List facilities provided by Model Airplane News.
