I said I’d update… better late than never, right?
I’ve been really happy with this charger. It has functioned flawlessly for over 3 years now. It delivers plenty of juice to keep the horses’ respect and even shocks reasonably well through the summertime weeds that inevitably get to the fence. My only minor complaint is that the shock is a lot weaker during the daytime than it is at night-- I don’t know if this is typical of all models or if mine has some sort of minor flaw with the battery, solar panel, or wiring. But when the sun’s out, it just delivers a sufficiently uncomfortable zap. When the sun goes down, the thing will knock you off your feet! I can’t complain too much, it actually makes me feel better to know it works so well at night when visibility is low.
However, for the first time in over 3 years, I went outside tonight and the charger was not working. The red light was not flashing. When I hit the power button, it turned on for a second, but then powered off immediately. I’m assuming the battery has gone kaput and plan to pick up a new one tomorrow if possible. I have no idea if 3+ years of continuous use and abuse is typical life for a 12V battery on a solar charger. Between the short days, a lot of rainy weather, and the fact that there are still some weeds touching the fence in places, maybe it was just too much for an older battery…
