After Christmas I will most likely look at the equalization (or conditioning) charge steps in the Lifeline manual. We wanted to take it on the Christmas trip, but since that would be the maiden voyage, and there is one heck-of-a storm rolling across the plains, discretion will be the better part of valor for us. When I get back I will have a chance to put it on shorepower for several days to get the charge up first. These batteries were on the dealer's lot for a long time, so Heaven only knows what state they are in now.
CAUTION!!

Conditioning Lifelines is a very exact and tricky process that should not be done without proper equipment! Be sure to talk to Lifeline tech support for the correct method of conditioning, or you could easily ruin them from overcharging or thermal runaway!.

Thank you for the warning lewster. My caution is exactly why I haven't already jumped in and tried "conditioning". If I get to that point, after I have gone as far as I can otherwise....I will definitely be in touch with the "techs". I have read the instructions from Lifeline, but experience has taught me to get the guidance from someone with hands-on experience before moving ahead. The manuals (Magnum and Lifeline) are pretty clear, but I definitely want the tech to be on the phone with me when I push "start" on the conditioning. Frankly, I am not convinced I need to take that step just yet. I am getting some positive results with better power management and extended shorepower charges. Working on a 7 day charge right now.

I am keeping the van in our driveway, plugged into shorepower, for the next week. The trials continue, but it is looking like I am gaining ground (or at least experience) in battery capacity. I will have the batteries load tested later, but at least it isn't as urgent now.
If everything was turned off and the solar panel only kept them at 50%, then I'd suspect something in the system. I'm in the KCMO area and we had several cloudy days in a row and it stayed @ 100%.

@73shark....I do think something is wrong somewhere. I was just happy that they did not drop further in that week I was away. I have been unable to spend much time trying to figure it out.....that time of year. Now that holiday travel is over I can spend some serious time checking things out. and no I did not take the van on the trip. We went into snow country and I did not want to risk getting that "first dent" with less than 200 miles on it. When it stops raining here, I plan to attack with my ammeter first, to see if I do have an unidentified load somewhere. If not, then its off to have the batteries load tested. The journey continues.....just one step at a time.

and another observation....... I have had my 2013 Interstate EXT on shorepower for 5 days now. I have the Magnum Inverter/Charger. Unless I am mistaken, I should see "Full Charge" sometime....... I have seen only "Float" since the evening of Day 1. Did I miss something somewhere? Conditions are: temp ranging from 25 at night to uppe 30's in the day time. Minimal direct sunlight. Nothing turned on in the coach, in fact the 12v disconnect has been in "discnnect" for last 2 days. Still learning folks.....

Your batteries ARE FULL if your Magnum is reading 'float'.

Yes - it has taken me 6 months to understand the way the Magnum works and I now trust it and keep it plugged into a shore line when it's garaged at home.

Seems like in Arizona, the solar panel would keep them charged unless you have stuff turned on.

You're right - it does when parked outside. But like everyone else there's a drain that I have to contend with, and the shoreline copes with it, whereas the solar panel doesn't always.

Thanks for the clarification lewster. As I said.....still learning.

House battery for 2006 Interstate Parkway

I am looking for a recommendation for a new house battery for my 2006 Interstate Parkway. The house battery is located under the passenger seat and the battery tray and hold down is sized for a Group 49 (H8) battery. The hieght must be about 8" or less. When I mention this battery size to sales people they only have starting batteries or dual purpose batteries that will fit in that space. The "experts" say I should have a deep cycle battery but they tend to be much taller than 8". Is a dual purpose marine battery adequate?

I think Doug&Maggie will need to weigh in on this; I seem to recall they have the house battery under the passenger-side seat in theirs, and modified the seat pedestal to gain some extra height. But my memory has been known to play tricks on me, so I'm not entirely sure.

If you have to be limited to placing your house battery within a limited space….think out of the box!

If you go with a Lifeline AGM battery, you can place them in any position except terminals down. I regularly install Lifelines and place them on their side, giving you much more 'headroom'.

Depending on the size you choose, most popular sized lifelines have a width of less than 7", which when placed on their side, becomes a height of less than 7". Here is a link to Lifeline's size specifications and battery sizes: Lifeline Batteries - Marine & RV Deep Cycle Batteries
