Ccab, the batteries charged on the wall wart should be charged for 15hrs before first use. After that, it is good practice to put them on the charger about 8 hours before going flying. A Nicad will not hold a full charge like an alkaline battery will, so even if your plane has set around for a couple days, it is a good idea to top it off before going flying. In use, you should get around 30 minutes of flight time, depending on the MAH (MilliAmpHours)rating of your batteries.

On the field box, if it has one of the 7Amp 12V batteries, it should hold up for a few weeks of flying every other day before needing to be charged again. If you are using a glow stick, they should hold up for a week of every other day flying, but it wouldn't hurt to top them off every couple days. The 7amp 12V gell cell battery will hold a charge for a few months in storage. The glow stick is like your receiver and transmitter batteries, the charge falls of in storage, so if you haven't flown for a while, you shoud top it off the night before you go out.

A good battery cycler would be a must in my mind. Every now and then, I cycle my batteries a couple times just to see how they are holding up. I usually use the wall wart for every day charging though. The exception is my one plane that has a 6V battery and that needs the battery cycler to charge it.
