Jeep Storage - Battery Tender?
When I bought my 2011 WK2, I handed-down my 2000 JGC WJ to my 22 yr old son (happy boy!)

He is currently living and working in Boston and has no need or space for a vehicle. So, it sits here in my driveway, w/no garage.

I've lost charge on the battery once or twice, so now I give it a run every week or two to keep it charged and to exercise the mechanicals occasionally.

This week, the Jeep really complained when I tried to turn it over (cold morning). It did finally start, but I am concerned even my ~weekly jaunts are not enough to keep this guy charged.

Removing the battery when not in-use is just not feasible for us (no garage, pain in the butt, etc.). I'm, thinking of a battery tender, but hate the idea of stringing a >50ft extension cord out to the Jeep, especially in winter - my snow blower would eat that cord, no problem! ;)

I saw a solar powered version over at, but I am concerned that this just might not provide enough juice to keep the batter charged.

I would probably mount this inside the windshield and simply route the wire to the battery terminals. Tinted windows a concern?

Any ideas to address my problem??

You should only need 50-100 ma and in bright sunlight the 5W is rated at 270 ma. The question is how much of that do you get this time of year ? The web site does not give a sunlight vs output chart. I don't see how it could hurt anything.
