Fence charger question

I have been offered a 2 year old Red Snap'r LI30 (low impedance, 30 mile) fence charger for $40, less than half what it would cost new (~$95). The reason it is being sold is the person is moving halfway across the country and doesn't want to bring it along. It's stated specs are 1.8 joules output, and 3 joules of stored energy. According to some test data I found on a Canadian website, the measured guard voltage was 8960V on a clean 3.3mi run of fence, and 3900V on a weedy run. Over a 10 mile run, clean was 5870V, weedy was 3290V. For a 3.3mi run of fence, the shock intensity was listed as being 2.2A @ 0.4J dry, 39A @ 2.5J wet. Over a 10 mile fence run, it was 1.5A @ 0.2J dry, 32.9A @ 2.1J wet.
Does this seem like an adequate charger for sheep & goats for 5 acres? I want to divide the property into 3 or 4 permanent paddocs with HT wire(6 or 7 wire), then have the animals in one or two smaller areas with temporary electric fencing. I know it's not a Gallagher, but for $40 it would be stupid to pass up if it isn't a pile of junk.

Hmmm you left out a lot of stuff. Where are you is it battery or AC or solar.
Trying to compare fence charger specs is an exercise in frustration as many of the companies deliberately make it impossible to campare theirs to other brands. Now most any decent charger will charge a 5 AC fence. However my personal experience with the inexpensive chargers is that they fail about every two years or less. I have 3 of them in my shed right now.This is especially true if you live where there is lots of lightning or in an area that is very dry like here in Arizona. Units that are not gounded with lots of ground rod will self destruct in short periods of time. If this thing was used constantly for two years I would buy new. If it was just run for short periods of time it might be worth $40.

Sorry, I live about 30 miles north of Spokane, WA. It is an AC model.
This is especially true if you live where there is lots of lightning or in an area that is very dry like here in Arizona. Units that are not gounded with lots of ground rod will self destruct in short periods of time. If this thing was used constantly for two years I would buy new. If it was just run for short periods of time it might be worth $40.
It's not super wet or super dry here, lightning isn't too much of a problem. I don't know how it's been grounded, or how regularly it's been run, I'll have to ask.
Thanks,
Julian

Julian, based on what you describe I think it would be fine. I would actually be more inclined to look at the fence and make sure its set up well. Make sure its good and tight and that the hot wire is not touching anything.
Seems like a good price as long as it works.

We ended up with two fence chargers on 6 acres, that way if one breaks you use the other one until you get a replacement. We implemented ours by putting knife switches at the half way point of the fence run. They stay open while we have a charger attached to each end. If we have a problem, we disconnect the broken charger and close the knife switches. It also makes it a little easier to debug problems. If you have a problem, switch chargers and see if the problem follows the fence or the charger. Reduces the walk by about 1000 feet.
