+1 for cares a lot Sharon.
In fact I am living in my Scamp as well, though I am given a site in a state park with AC. What that means in real terms is that, to this point, I am depending on my PD charger to keep my batteries charged.
PD tells me that they aren't ever going to do so, thus my search for the technology to do it around the built-in charger.
In fact it is probably charging them to the 80% point. Which is not going to immediately ruin them. However I do not have the charge wizard thingie. Just putting the wizard on them will likely do what they refer to as "de-sulfonation".
Since my batteries are not (yet) sulfonated, what this really does is cause the solution to boil, which keeps it mixed. The solution in the battery will separate and this process "mixes it up".
Folks in this thread and elsewhere have talked about how bad "boiling" is, in fact it is a necessity, just to keep the solution mixed.
Boiling endlessly is bad. ALL boiling is causing a certain amount of the water to break down into hydrogen and oxygen
atoms, some of which escapes (in a non-sealed battery), which "uses up" the water. That is why we have to add distilled water to our wet cell batteries, to replace the water "boiled off". All of that is quite normal however, not necessarily a bad thing, only in excess.
By the way, the AGM (glass mat) batteries also boil, however they are sealed such that the gasses cannot escape
and, over time, the hydrogen and oxygen
recombine to form the water that was broken down originally. Thus (hopefully) no fluid loss.
Unsealed batteries can be charged much faster than AGM batteries exactly because the gasses can escape
. We just have to add water occasionally. AGM batteries, being sealed, cause internal pressure as they charge (and boil) and thus if you charge them too rapidly, the pressure will get high enough to rupture the battery, obviously not a good thing!
There is a whole lot of myth and magic in the minds of our members. None of this is magic, it is just physics and chemistry at work. The BATTERY MANUFACTURERS tell us how to charge their batteries. Most of the charger manufacturers ignore the recommendations. Or perhaps under charge in order to reduce the boiling which reduces the maintenance (replacing the water). But over charging and under charging are both bad for the batteries.
Not to mention that we want a full charge because we can only draw down a battery to the 50% mark before pretty serious damage starts to happen. Even 50% is not a magic number, there is some damage occurring already at that point, but it gets REALLY bad if drawn down below that. Stopping use while 60% full would be better.
So... if my battery is a 220 ah battery, and is fully charged, then I can pull 110 AH out of it before I hit the 50% mark. If my charger only ever charges the battery to 80% then instead of 50% of the "available" capacity, suddenly I only get 30% of the capacity because I am starting at the 20% discharged state. Suddenly I only get ~77 AH before I hit the 50% mark. I am not starting from fully charged any more.
I don't know about you, but that affects my life and my pocket book.
As you might have read in these threads, there is a lot of "good enough for me" kind of comments. To which I reply, "I'm happy for you." but good enough for you is not necessarily good enough for me. I paid for 110 AH!!!
At the beginning of this thread we were discussing Amp Hours that we each use. My AH rating / day is probably about 20-30. If I am pulling 30 AH per day and my battery is giving me 110 AH before I have to stop using it, then I am good for 3.6 days. If it is giving me 77 AH because my charger isn't getting it full, then it is giving me 2.5 days before I have to stop using it.
This is a real effect. I am not going to make excuses for the companies doing stupid stuff. Scamp should place the charger at the wall next to the battery. They don't. That is a BAD decision. PD should listen to the battery manufacturers and charge the batteries all the way up. They don't.
Like yourself, I do care.
The question then is, what can I do about it? NOT ask here because all I have gotten so far is yada yada excuses excuses good enough for my purposes...
