BATTERY TEMP FLOAT VOLTAGE CHARTS NEEDED

Here's for Full River AGM- you can see the huge difference between FR and Lifeline- if a person wants this info, they really need to get it for their specific battery, as I doubt generic charts would be good.



FWIW, I'm getting ready to replace 2 US Battery AGM GC-2's that have failed @ just under 5 years with 2 Full River DC-224-6 @ $224 each.

And IMO, if float voltages were that critical, I'd think the industry would have temp compensation built in all chargers.

Agree not critical to a point (although apparently hi 13's is critical to some :B) but the reason for not adding temperature compensation is obvious.
1. It cost more
2. The batteries will outlast the warranty
3. The typical RVer is clueless

I have a heck of a time with ignorance of the cellular and drop down screens saying (cannot connect) down here. Thanks. Let's hope more folks chime in. I'll get Eduardo to make copies of the sticky for me then laminate them.

Float temperature correlation really should not mean much to individuals who live in an environment that may span 40 degrees F between seasonal extremes, own a few batteries, and manage them by guessing. When temps vary 130 degrees and expensive batteries are involved it's a different tinted pony.

This sticky shall be for the battery charging and extended battery life purists, as well as those that are curious, and want to learn.

I would suppose the more you have invested in your batteries and their replacement cost, on your rig, the more interest this should be to you.

The Paramode converter with Temp Assure has temp comp but no type of battery settings. In the Paramode I had a couple years ago (it fried itself somehow) the "nominal temp" was 60F rather than 77F like some of the other specs.

Its temp sensor goes on the ring lug that goes on the battery on a long wire from the converter.

When the converter goes inside the trailer and the batteries are up front, you have a heck of a time routing that long wire.

The portable charger, VEC1093DBD, has a built in temp comp, but I don't know what "nominal" is. It definitely works. You see it doing higher voltages in the winter than in the summer. It doesn't actually have Float stage though.

Fine, but who is it going to help,....the real technical minded,....that I'm sure know it all already ?
Its not like the average RV'r has control over float voltages.
And IMO, if float voltages were that critical, I'd think the industry would have temp compensation built in all chargers. My battery tender does, but my PD doesn't, neither do all the other maintainers I have around here. And I for one, NEVER have battery trouble, nor do I have any complaints on how long my batteries last, especially the RV batts on the PD 24/365-
But however, I do have voltmeters all over the place, and if I happen to see a meter crowding the hi 13s at 95-105 degs, I just unplug it for a day or 3.
I have very good results w/ batteries just keeping it simple.
But, I'm the weirdo that don't use hydrometers either !!
