Battery capacity is defined by the 20 hour rate at 0°CThe oil specification should be for the minimum ambient temperature as the oil will not be warmed by the immersion heaterBreakaway current is dependant on battery capacity available. Cables should be capable of handling transient current which may be up to double the steady cranking current.
