8D Battery Longivity

Yahoo Message Number: 109816
Hi Folks,

With 18 years of acid flooded cell battery maintenance on my motorhome and tasked by the Air force to provide them with their maintenance at Airforce bases and depot overhaul, I share with you an approach for battery longevity.
Do not use the motorhome onboard inverter/battery charger during storage. That means over two days.
Instead, use a charger that can be set for 13.4 vdc. That way the 8D house battery bank will not be overcharged and the start battery will be also have a maintained charge. I recommend using distilled water with 1/2 inch minimum and 1 inch maximum level maintained.

I am totally ignorant on what you are saying about battery storage. The electrical system on my unit must be having issues as I must use the Boost switch each time I crank the C12 engine. Suggestions are appreciated.

Fred,

Good morning!

I have a few questions for you . Please call me as I am on my way now to the storage facility to store my coach for months.

Fred - Do you qualify that recommendation based upon the inverter/charger type and age?

The MS2812 we installed along with the Smart Battery Combiner, has worked flawlessly for us for over three years now.

We have Lifeline AGM's for the house, and a CAT 8D Maintenance Free for the chassis. Magnum charger set to the Lifeline setting, vs the rest of the AGM manufacture's settings. (I called Lifeline, and talked with them quite a bit about this, as I also had an option to set custom levels for Bulk/Absorb/Float. The tech at Lifeline said that with my X's 4 L16 bank, I probably could have safely sent more juice then the standard Lifeline setting. He said that Magnum consulted with Lifeline extensively on the values.)

I do have the temperature sender in the mix too, which I feel also helps protect the batteries.

Never any sings of cooking of the Chassis Battery.

I will also note, that we have a MidNite Classic 150 Controller in the mix, fed by 1200W of 48V solar.

The MidNite Classic 150 and Magnum MS2812 have played very well together. The Magnum Smart Batter Combiner does not care where the power is coming from to the House, once it detects all is well on the House side, it diverts power to the Chassis.

I will agree that in my Bounder, and even with the first charger/inverter we had in the CC - that I would see evidence of the House and Chassis battery outgassing.

My main reason for posting, is to validate if your caution was more for these older inverter/chargers?

TIA, and best,

Smitty

Leak in Storage Bay Compartment

Looking for a little help with a leak. I have an 07 Allure 40' Hood River, that is currently in outdoor storage (with the slides in), we have had an unusual amount of snow and rain for about the last 8 weeks. I recently found the leak in my rear storage bay on the driver's side, there is no sign what so ever of the leak showing up in the slide, walls, floor or ceiling directly above the storage bay. The gray carpet on the ceiling in the bay is extremely wet especially on the driver's side right next to the outer metal channel rail on the ceiling of the bay, the moisture is being wicked inward on the ceiling carpet and also down the vertical walls of the bay. My propane bay is immediately forward of the wet bay and my plumbing bay is rearward, both bays on either side of the wet bay have no signs of water entry. At this point I have not started to pull the bay apart as the weather isn't co-operating too much. I don't have access to power in the storage lot so I'm hoping to get a dryer and fan in there in the next day or so by using the generator.

Any suggestions or thoughts from those that may have had the same or similar issue would be much appreciated.

Thanks
