where to charge from

Truck been setting weeks now. Going to put charge on it. Is the jump start lug under hood good spot. Or do I need to go to batteries

 

As GeorgiaHybrid said, Glenn, I've had good success with using the jump start lugs on my truck for charging/maintaining the batteries.

Jump start lugs are probably positioned so they meet two "requirements": safe separation from each other (to prevent arcs) and relatively close to starter (to avoid losses in long copper runs). Batteries get positioned where they're out of the way, out of the spray, and easier to replace. Putting your charger on the jump start lugs probably results in a little bit of resistive loss in the cabling, but if your charger is strong enough, 90% of strong enough is probably still strong enough.

Solar or 110v?

 

When I have shore power it is 110v.

 

When on solar, my Blue Sky charge controller has an aux charge mode that switches over to charging/maintaining the start battery after the house batteries are topped off. It's a pretty slick system.

 

Not a big deal when we are on the road, but my rig sits for several months at a time because we are not fulltime yet.

Lots of parks I'm in truck can't be on site with me. Like here it is at park but not on my site. I had to run 200 feet of cord to charge. I will be getting solar for it.

 

Sounds like a good idea. Solar maintainers are inexpensive - you don't need a huge amount to keep the batteries topped off.

Solar panels work great as battery maintainers. Since batteries at rest, disconnected will see a discharge of around 10%, it doesnt take much to compensate. I've used some from Harbor Freight that seem to have done the job good enough. And the price is reasonable. Just dont treat them too rough, they arent very robustly built.

I haven't used a charger on my truck for over 2 years. I have the harbor freight panels set up to keep batteries charged. The truck sat for 4 months this winter and restarted with no problems. It will probably sit another 4 months while,I do chemo this summer. Expect it to restart with no problems.

Glenn, do you have a way to take a picture of your jump lugs and post them? I checked our truck and I only see the posts on the starter, no other lugs on the drivers side under the hood that I could see.

Similar to this. About the size around of a roll of dimes, or pennies.

I put a 33 watt panel that I had on my truck with an inexpensive controller. It is usually fully charged and switched to float by noon at the latest. We are normally in the western or southwestern US where the sun is abundant but it has never failed to keep the batteries charged. I don't disconnect the batteries from the truck either.

in the winter we will park trucks for months with the batteries disconnected by switches. Turn the switch and the vehicle comes to life. ... battery cut off switches are a parked HDT's best friend vs yet another "system" to chase and maintain...
