How long will a 12v keep an electric fence up?

The Fence is an electronet from Premier (maybe 160 ft, can't remember). Weed load will be low in some places, moderate in others. Fence will only be up from dawn til dusk.

Any guesses?

Do you have a charger with that battery in it? Call Premier and ask.

the more it has to work the shorter the life. try a solar fencer.

Patriot P5 AC/DC Energizer - Premier1Supplies

This is the charger. I originally bought it for poultry. Will it work as a day fence for goats? They will be in a secure stable and pasture if we were to be away for more than an 8 hour work day.

No info on Premier web site on battery life. thought someone could give me a ballpark figure.......one week....two weeks....a month? I would probably use a middle of the road car battery unless there is some advantage to using another type.

Draw from a 12v battery is 42 milliampere (mA) per hour. With this energizer a 12v 100 ampere hour, deep cycle battery will last approximately 59 days* on a clean or a weedy fence. *Assumes being drawn down to 40% between recharges.

Right from the info on your charger

Well, I already have this charger. If i went solar I would still have to buy a battery AND a Solar panel ($$$$). We're talking light duty temporary fencing 100yds away from the house, not semipermanant pasture on the "back forty".

I figure I can easily bring the battery up to the house at night and charge it. Just wondering how often that would need to be done.

probably would like to keep battery above 60% discharge to get any kind of life out of it. figure two deep discharge batteries (about $200) to rotate while one is charging.. seems like i could get about 30 to 40 days out of a battery,,,,before i went to a solar panel with charge controller. sooner or later you forget and ruin a battery...

Always figured about 30 days out of a battery. Battery is any old battery that will hold a charge. I wouldn't buy a new battery for a fencer, the new battery would go in a vehicle and the old vehicle battery would go on the fence.

I'd give it a whirl! Can you report back after you get it up and running? It would help lots of folks.

Allen has the right idea. And, any old battery will do a good job if you don't have a lot of shorts to drain it.
