“The Power to Exceed”

2. Number of Cycles based on Depth of Discharge Temperature in Celsius
Power Requirements
Depth of discharge and operating temperature effect life expectancy
With hotel loads today you can expect a nightly discharge rate of 30-60% excluding
Less idling will save fuel increasing the return on investment
