Battery stuff

Day 23

35 Amp-Hours
Does Not Cut it!

6:57am:
Scampy had an Interstate Deep Cycle Battery on her tongue. This battery weighs 50 lbs. This battery has a 96 amp-hour rating

We have replaced the Interstate, with a Mighty Max Deep Cycle Battery that weighs 23 lbs. This battery has a 35 amp-hour rating.

We did this change in order to give mounting space on Scampy's tongue for our new dual propane setup. Also, to remove 27 lbs from Scampy's tongue. We did not know how the Mighty Max would do on-the-job. So, a couple of days ago, we took Scampy off of Lone Wolf's shore power.

Last nite, the 2nd day off shore power, the Mighty Max voltage fell below
10 volts! In other words, Mighty Max became So Sorry Max!

We awoke to the sound of our Propane Detector going off. But, the Propane Detector went off because of the low voltage, not for propane. So, we went outside and plugged back into Lone Wolf's shore power again.

.


What to do?
Our plan now, is to connect up the Interstate battery to the Mighty Max battery in parallel. That should give us a potential 131 amp-hours.
[96 amp hours + 35 amp hours = 131 amp hours]

That should put us way-over-the-top!


8:02am:
Belgian Waffles again?
This morning, when I went outside to check battery conditions, I spotted our new Nordic Ware Belgian waffle iron in the storage area of Tr├ínsito.

And, I brought the waffle iron back with me on returning to Scampy.

Just love the way that Nordic Ware bakes waffles! ­čśÄ



7:34pm:
New water heater
Today over at Kelly's RV, we had Scampy's manual water heater changed out for a water heater that has an igniter.

All that I do now,  is hit the switch and the heater goes on! Gotta love it.

While the tech was installing the water heater, I did some massive tweaking to Tránsito's storage area.

Everything that I had intended Tránsito to have in his storage is now in. Even a
travel suitcase [carry-on]. The travel suitcase has all of my clothing that was formerly hanging in Twayler.

Everything fits perfectly! And there is still room to spare!

  1. And to keep you on the safe side, if you have a bathroom scale, you can put it under the hitch to determine the tongue weight to be sure it doesn’t exceed the Ford / hitch manufacturer recommended limit.

    1. Ed,

      Yes, tongue weight is important. I'll be careful.

      Thank you,
      George

      PS: I just checked out your "Ed & Carol" Blog. Very lovely Blog! I liked it!

  2. Going to order your Nordic Ware waffle iron today. I love waffles too. It seems the iron can be used over open fire too for camping...am I right?

    1. Hi Rita,

      Nordic Ware Belgian waffle iron over a camp fire?

      If you want a waffle that is perfectly baked, it seems to me that there is very little heat control over a camp fire.

      Better to go into your RV's kitchen, and use your propane stove. Whatta ya think?

  3. Though they will cost more, but last longer then a standard Deep Cycle Battery. AGM Batteries can be safely mounted in varying positions inside the Trailer because they give off no gasses when charging. Mounting it close to the Axle would solve your Hitchweight issue.
    Be Safe and Enjoy!

    It's about time.

    1. Hi Rick and Kathy,

      Are you suggesting mounting the batteries over Scampy's axle? That would be an interesting thing to view!

      The Mighty Max battery is an AGM.

      In your comment, you wrote:
      "It's about time."

      I am wondering what that time would be?
      Love? Sex? Rock n' roll?

      Comment back and please let me know.

  4. Mismatched batteries do not work well at all. Even matched batteries that are more than a few months apart in age can be a problem.

    1. Hi Otto,

      What kind of a problem would that be?

      I guess that I will find out, because I intend to do it

    2. Read this on rvforum.net: "...you want to have batteries that are matched in size and condition, if not the stronger of the two is trying to 'charge' the weaker one which reduces the effective use of the two. In other words, you want them 'balanced' so one isn't being wasted trying to support the other."

    3. As batteries age, it takes slightly more voltage to charge them and they produce slightly less voltage when they are used.

      If you have mismatched batteries, the newer one will work harder than the older one, charging more fully and contributing more power to the load. Meanwhile the weaker battery just loans along, neversus getting fully charged and not having enough stored energy to do it's share of the work.

      It will be difficult if not impossible to get both batteries working equally.

  5. For added safety while boon docking you might consider getting a GARMIN Inreach Explorer Plus and a subscription plan for satellite connection. You'd be able sent text messages and get help even where there is no cell phone service.

    1. Hi Eric,

      I took a peek at the link you gave. Interesting idea.

      I'm a Blogger. If I cannot Blog every day, I am not a happy RVer.

  6. In answer to your question mix amperage batteries the answer is no it won't
    Now for the technical version
    There must exist a voltage level difference between batteries in parallel for current to flow between the batteries (higher voltage battery to lower voltage battery).

    If you have a battery that is 12.6v rated at 125 amp-hrs hooked in parallel with a battery that measures 12.6v rated at 60 amp-hrs, the 125 amp-hr battery will not try to charge the 60 amp-hr battery. As long as the voltages are the same there will be no current flow between batteries.

    If the 125 amp-hr battery falls below 12.6v the 60 amp-hr battery will try to charge the larger capacity battery to get the voltage back to 12.6v.

    Don't confuse battery capacity (amp-hrs) with battery potential (voltage). The reason for having batteries of the same "capacity" and "make" is so that they will decay at approximately the same rate and not become parasitic of one another.

    The converter for all intents and purposes prevents parasitic charging as its voltage is higher (13.2v to 14.6v) than the batteries (this statement assumes that one or more of the batteries is not in such bad condition that it is dragging down converter by exceeding its charging current capacity). If you are not running the converter then parasitic charging can and will occur if the batteries do not decay at the same rate thus creating a voltage difference.

    1. Hi Ed,

      What I will be doing is, connecting both batteries in parallel to the solar panel.

      I shall let you know what happens.

    2. If you're going to do it as a test
      When you hook both batteries up in parallel use your multimeter numerous times throughout the day and record what readings you have from each battery.
      an written down and you'll see the results better

  7. I think Ed is mostly correct in his thinking. I've always been told, by knowledgeable sources, not to mix batteries.

    1. Hi Thom,

      Sometimes you gotta take yourself in hand, and say:
      What the hell!

      And then not worry about anything.

    2. Careful . . . Was that attitude with Wave 3 hookup and propane detector placement. Prior research never a waste.

    3. George, Mister Ed and Barb gave you correct and good information. But it's your choice to take a "What the hell" attitude. If you don't believe it, why don't you do some research. But then again, what the hell!

    5. Ed,

      You are taking the rule about not using dis-similar batteries in a bank as if great harm will come.

      Not so!

      Tne amount of harm is negligible.
