[Shop-talk] Solar car battery chargers

[Scott Hall]

  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
