Even if you do run it all session, you don't have to run it on full heat, so using a Kenrick controller (or other PWM controller) you can extend the life of your battery.
For example last night I set up about sun set with the dew heaters on about 25%. After twilight when thing started to cool quickly, I cranked it up to about 75% but a couple of hours later when it looked like the dew just wasn't going to happen, I dropped it down to 25% or so again. If the dew hits hard and heavy, you might need to run it flat out. It's prudent to run the heater before you get dew forming... its far easier to keep it away than to evaporate it afterwards.
If you are interested I had a dewpoint table somewhere. If you know your relative humidity and can get a forecast of the expected minimum temp overnight, the table will tell you if you'll get dew or not and, with some experience, will give some indication of how heavy the dew will be. Had I been deciplined/organised enough to use it last night I might have known I wouldn't need the dew heater
