This is our fourth day boonies - with no charger. I ran the truck one hour yesterday, after three days. I ran it a half-four last night. And am running it this AM for half hour.
Each time, I get the bright Green market lit - I know, not a great indicator, but when it's lit, I've got good power in the battery, even if a super tech reading tells me something different.
Here's a weird reading (to me anyway) Woke up, read truck battery at 12.88, read TC battery at 12.13 .... started truck, read TC battery at 11.79 steady...
went back and read truck running, 14.3 (bounces around a little.
I assume I'm reading it right - I have a voltmeter, turn it to DC and '20', and put red spike on positive black spike on negative, and read the digital dial.
Am not always sure what everything means electronically, but I can at least figure it out with a little coaching. but have never worried about this, as I didn't care so much about battery - now, we're sitting longer in the boonies, so it makes a difference.
we ahve the availability of power any times I want to drive there (few miles) we are now "testing this battery issue" at a local CG with no power - we're planning a five months trip with lots of bonnies camping, and want to decide if we need a geneator - would prefer not. But want to enjoy it, and not fight the battery. But giving up that space and carrying extra gas is somewhat a hassle, so am giving this a try first.
I thought this was an easy Q - but no quite as easy as I thought. It looks like I will not need a generator because this is our fourth day - and all is fine with power. If we can do four days at once, that's our plan, and hen head to FHUs after four boonies days on this trip we're planning. So, from the looks of things, we can do it with the truck. I know, I know running the truck takes fuel - but so does generator, and carrying more fuel, and carrying the generator, and buying it cost a lot more than the fuel we'll spend in the truck.
does anyone have comments at this point in the 'test' ... and thanks for all advices.
Good idea to 'test time' the charge rate from home current - that would give me the charge time needed after one night on the road. Btw; we use whatever power we want on the road camping, we don't skimp' its juts that our camping style does not use a lot of battery. We don't use MW, TV, Movies etc unless we have FHU, it's just a way of camping we enjoy. SO, works well for us ... might not for others.
