Rating definitions

Prime powerVariable load. Unlimited hours usage with an average load factor of 80% of the published Prime Power rating over each 24 hour period. A 10% overload is available for 1 hour in every 12 hours operation.

Standby powerVariable load. Limited to 500 hours annual usage up to 300 hours of which may be continuous running. No overload is permitted.

Emissions capabilityCertified against the requirements of EU2011 Stage 3A legislation for non-road mobile machinery, powered by constant speed engines.

Cold start recommendations

Notes:Battery capacity is defined by the 20 hour rateThe oil specification should be for the minimum ambient temperature as the oil will not be warmed by the immersion heaterBreakaway current is dependent on battery capacity available. Cables should be capable of handling the transient current which may be up to double the steady cranking current.2506D-E15TAG2 maximum additional restriction (duct
