Watts Help Needed.
I am trying to figure out how long a battery will last. I have Googled it and read a few sites but I still have a few questions. I have a small TV that I plugged into my Kill a Watt meter. That sho...

"automatic" means it shuts off and does not go into float mode.
"manual" means it does not shut off and you have to unplug it before the battery voltage goes too high.
"regular charger" means it just brings the battery up in voltage and then shuts off (if automatic type)
"RV converter/charger" most have "three-stage charging" ( three different voltages ) and stays on to do the float charge. it is "automatic" for changing its stages, but it stays on.
"adjustable voltage charger" -you pick a voltage and it stays at that until you change it. so it is "manual" for that. Charger stays on. It is not "automatic" --you have to change the voltage from charging at say 14.5v then when the battery is full you can drop it to a float voltage, say 13.5.
The Megawatt is like that last one. The PowerMax LK model of converters has three-stage automatic or you can set it to adjustable voltage. If you have the adjustable voltage set to 14.5, say, then you need to change that when the the battery is full to a float voltage, OR you can use Mex's timer to just turn the thing off, guessing how long to leave it on for.
My suggestion is to pick the car type automatic charger and when it shuts itself off, then you can turn on the Tender to do the float , which you can leave on as long as you like. No timer, no complications.
