I have two of the Harbor Freight 5 watt solar units. They work. Only issue I
have with them is the heat.
They get moderately hot. Normally I use something non-combustible to keep them
off the dash.
I also have the battery minder charger/desulphator. They all work. The solar
chargers are a little
more convenient when you want to go the vehicle, get in, do what you want. With
the battery minder,
you need to roll up the extension cord too unless you don't mind leaving it
sitting in the driveway.
The desulphator worked to recover a few weak batteries I had, but they have
been
regulated to
secondary use as they all went back to being too weak to start the vehicle as a
primary battery

Subject: [Shop-talk] Solar car battery chargers
Because the truck is moving out of the shop, so I can have the room it's taking
up, and because i know some of you are not just EEs, but actually apply it as
well.
I'd like to use a solar trickle charger on my F250 (diesel) to maintain the
batteries over long period of un-use. I was about to buy the $30 trickle
charger off Amazon
(http://www.amazon.com/Wagan-2017-Solar-Battery-Charger/dp/B000VHT9GS), but I
wonder if the truck having two batteries means anything (like if I should get a
bigger charger). Then it occurred to me that $30 might not buy a lot of
charger, so I thought I'd throw it out to the list. Anybody keeping something
with more than one battery topped up with a solar charger?
Thanks,
Scott
