How long to recharge battery from shorepower?
The few times I have camped without electricity I have left before the battery was exhausted (two days) or I jumped it from the truck for 15 to 20 minutes to get through a third day and into the fourt...

Yah, definitely turn off all the devices that you are not using. With just battery power, the antenna amplifier isn't doing you an good anyway unless you are running a TV off battery power as well.
I agree with the "fast charge" statement. you can put some power back into a battery fairly fast, but it is very hard on a battery and you will never get a full charge that way. Batteries don't do well in a partially discharged state for prolonged periods. It is a leading cause of battery failure. I always use a charger/maintainer which only drops 1.5 to 2amps into the battery unless the battery is under half charge, then I will put it on the regular charger for few hours and switch to the charger/maintainer after that to get it fully topped off. I have a 6 year old cheapo battery in my riding mower that starts my mower like the day I bought it. I get done mowing and put it right back on the charger/maintainer. It sits in the garage between mowings and all winter long. My RV battery is three years old but really doesn't get a lot of use. but the original only lasted two years before I replaced it and started using the charger maintainer between uses. The one that I have also does a "desulfication" on the battery which is key.

The second battery sounds like your cheapest and least cumbersome solution. Good luck and have a great summer camping.
