I don't have the answer, but being a cynic I am thinking as follows:

A lot of manufacturers used to build "stuff" that would last forever. This is not necessarily good for business so most don't do this any more.

How many battery manufacturers would think this: "Let's make batteries that will last twice as long as they do now" I don't think this proposal will get the vote of the Sales Director.

Just a thought

In addition to using Mineral Oil in my eight battery bank, I learned to not allow total fluid level to actually touch the full battery ring when filling. Or, in other words, the water level is just slightly lower than where most people fill to. This allows the gassing (bubbles) to not be confined to that one area, but dispersed.

Can you tell me what model Magnum inverter/charger you have and what settings the manufacturer told you to use? We have a 2005 HR Endeavor which has had water pooling on the top of the house batteries following an equalization process and are trying to assess the problem. Thanks.

On the Interstate U-2200's we have there is a slot running vertically from the ring, even if filled to the bottom of the ring gasses can still escape with no trouble.

We had some friends with a similar coach and their battery bay was always bone dry. Two years ago I replaced my four Trojan 6 volt batteries with new Trojan batteries.

I called Magnum, the maker of my Inverter/Charger, to make sure I had the charger set correctly. They told me I was overcharging the batteries and gave me the correct settings. After that, my batteires quit off gassing.

I also added a batteyr watering system. They're pricey, but worth every penny. I now check my batteries about once every four months. I give the bulb a squeeze or two and the batteries are full. The BEST part, my battery bay is now dusty dry.

Not everyone has a battery charger that can be fine tuned for perfect charging, but I think the watering system is better than the oil or caps. It keeps the battery system sealed.

Don,
I'm with you on the magnum settings. I done the same thing a few years ago about calling magnum and they walked me through the settings for the inverter charger. I now have dry compartment and hardly ever have to add water to the batteries. They are set for only charging at 80% now instead of 100%. I think that is the readings anyway.

Bob,just look up the phone # for magnum on the internet and call them. They will walk you through the settings for your coach. One thing you don't need to do is equalize either. Just give them a call. They will help you.

There are a couple of ways to maintain a battery charge. Let's take Trojan battery's for instance. The maker advises, for the best health of the battery's, to charge to 14.8, and hold there for two to four hours before allowing to go to float charge.

They do mention on their Web Site, that there are those that prefer to only bring them up to around 14.4, and for a shorter period of time, and that that is fine, but may create the need for an equalization charge every once in a while. This method is also sometimes called the 80% method, and produces much less gassing, but with lower performance from them, not necessarily a bad thing depending upon need.

I find following Trojan's recommendation, but using Mineral Oil, fits my needs, longevity upwards of ten years, and absence of excessive corrosion. My batteries, however, are open to the outside through some screening, not enclosed.

nuckels11....As Bill2 stated, just give Magnum a call. They're REALLY helpful. Make sure you write down what batteries you have and what amp hours they are so you can give this info to Magnum. I don't, but I certainly could store stuff in my battery compartment because it's soooo dry and acid free. My batteries rarely take water and are always putting out max power.

As a question: So the motorhome vibration is such or so little that the oil and battery acid (distilled water) don't mix? That would be my concern but I don't think anyone has mentioned this as a possibility. Thoughts ???

My understanding has been that the oil will never mix with the water and remains floating on top... which is where the benefit comes from.

Thanks, OK I can agree water & oil in theory don't mix. If I remember correctly years ago a head gasket leak let water into the crankcase of one of my vehicles and it sure looked mixed to me. Granted it will separate once the water/oil have sit a bit. Apparently the coach road vibration is not enough to be a concern.

Oil and water won't mix in a mixing bowl either, unless you add a blender, which is exactly what happens when a head gasket leaks/blows.
