I use a trickle charger occasionally, generally only if I get an excessive battery discharge warning. My car tends to sit idle for as much as a week at a time (I'm away a lot), and the car is mostly used for relatively short trips - less than 10 miles usually - so the battery is often not fully charged. I throw the trickle charger on overnight and that fixes it.
