Hi George,
Let me stir the pot a little here. If I had been with you and the store clerk had made the statement "Hospital batteries have 3 times the stored energy of a regular RV/Marine battery", I would have asked him to ˜prove it'. I have been an X-Ray repairman for 30 years and 7 years as a Radar repairman before that. Unless he has found a way around the chemistry involved in lead/acid batteries, what he said can't be. And if it is, I think 35$ would qualify it as a miracle. I'm pretty up on battery technology and I've never heard of ˜hospital take outs'. Please reply with the Make and Model of those batteries. You sure tweaked my interest!
Captain Bud, have you checked the 'float' charge voltage. To lose that much water in a battery, it sounds like it's overcharging and boiling it away. This condition will also shorten the life of your batteries. Check your battery manufacturers web site for the proper voltage, it is type and temperature dependent.

I agree with you on the Hospital take outs, I personally think it's somebodys dream. Don't think I'm pouring gallons of water into my batteries, I just keep them topped off to where they should be. I have a solar hookup plus the normal battery inverter.

I hope George gets back to us with the info on these things. Like I said, my inquisitive mind is tweaked! Can't wait to check the specs.

I don't recall the info you requested. My invoice simply stated "Hospital Take Out Batteries" (supposedly hospital equipment uses these batteries as part of a power backup system and they have to be changed out at 12 month intervals) These did not have the standard threaded terminals. These had a square flat terminal, with bolt hole. I don't know if that makes any difference or not, but it is the only characteristic that was different about the case...oh yea...they were taller too.

Hi George,
Sounds like they could be standard ˜Portable X-Ray Machine' batteries. I guess "Hospital Take Out Batteries" means they ˜Took em out' of something, ergo used. Not much different than RV/Marine except you wouldn't want to pay the ˜New' price for them. My guess is that they are of the sealed, maintenance free type. Probably cost the Hospital around $200.00 a piece new. I doubt that the hospital changes them out on an annual basis. Normally the Bio-Med department will only change them when they no longer hold enough charge to provide power for a maximum power X-Ray exposure. Anything medical is quite expensive, not because it's that good but to cover the liability insurance of the manufacturer. With lead/acid batteries, power density is related to how many plates (read surface area) are installed. More plates equals heavier batteries. Make the plates thinner to bring the weight back down and you have a starting battery that hates to be discharged or deep cycled because the plates start to fall apart. RV/Marine batteries have thicker plates and can stand to be deep cycled. AGM batteries are a compromise on thickness which is made practical by sandwiching the plates between layers of very fine fiberglass allowing the battery to deep cycle without the plates falling apart.

I think it depends of what other replacements you put in. If you put in something that is backed by the likes of Costco or Walmart, I don't think you will get any less quality. Just less $$$ to pay for the battery. Do the math and it is pretty clear that purchasing replacements from Sam's or Costco is by far a better solution.

May I recommend that buying the same batteries that were installed, is probably the best route to take. I presently have Interstate Deep Cycles, and when they need replacement, that's what will go back in. Presently my coach Batteries are about 30 months old and I am watching them closely. My MH is plugged in 24/7 and the battery water consumption dictates a 10 -14 day check and fill. Remember you get what you pay for, don't nickel and dime it on your batteries... </div></BLOCKQUOTE>

I would highly recommend that anyone having to add a lot of water on a continual basis check the condition of the batteries and the charging system. This is not normal when both the batteries are in good condition and the charging system is of good quality and working properly. My house batteries (Interstate U2200) are 3.5 years old and I have had to add some water twice. One time in Az. & once in Fl. We stay plugged in most all the time. We have occasionally boondocked. I will equalize them about once a year since I don't rely heavily on them drycamping any more than we do. I have never had to clean the terminals as there is no excesive off gassing. Do some homework on this subject and you may be quite supprised

Mike - what is the impact of overfilling the U2200 batteries? Is it terminal? I just took delivery of a new coach and it has 4 U2200's. They had been overfilled by either the factory or the dealer - into the filler neck above the plates. Clearly they were going to boil over so I removed some of the solution fromm each cell. Now, the specific gravity is low. I put it on an equilize charge last night and if the specific gravity doesn't get up to something acceptable I guess I should insist they be replaced.

Any advice would be appreciated.

Thanks

Don

Mike, I just went out to check the 4 U2200's to see how they are after the equalization run. The specific gravity for all cells is into the green zone now (around 1.275 - before they were all in the middle of the white "fair" zone at 1.24 to 1.25). Since I equalized I assume the electrolyte was mixed and the reading I got on the hydrometer was not due to stratification (I hope this is a valid assumption). I'm going to check them again tomorrow.

Don

Don, be sure that the surface charge is removed by either turning on the lights for a few minutes or wating an hour after removing the charge. Did you by chance save the fluid removed? If so hold on to it so when you do have to add you could use it. If all cells were in the 1.275 or very close range you should bee fine. If one cell is lower then that cell is weak and could fail at any time.

Thanks Mike, I thought about saving the fluid - after I had dumped it (right on the grass as I was working in the dark, and then dumped a few buckets of water on the grass).

I'm going to monitor the batteries closely for the next few days.

Thanks again

Don

Just a thought on adding water to house batteries. I use a small pump up garden sprayer that has the plastic wand. I put the distilled water in and just pump 4 or 5 times as you don't want much pressure. It makes it easy to reach that third battery and not to over fill. I just replaced my roll out battery tray because the acid from over filling ate it up.
Safe travels, Jim Bob

Hi: I have a "new"2005 Itasca in which the batteries failed within 4 months.They were Interstate..I called the dealer and was told to contact Interstate who in turn gave me a dealer who sells thier batteries.I took the batteries to this location and they were replaced free of charge. I also know of another owner who did the same this with the same make of battery. They do have warrenties and should be totally covered within the warrenty time frames.

The first time we took our 2005 Suncruiser dry camping (only 4 months after delivery)the house batteries failed to hold a charge. Had to pay $240 to replace them (they had bad cells) and have put in a claim to WB for reimbursement. However, I plan to replace them at the start of each camping season with CostCo/Sam's club at $45 each. Why put up with the hassle on the road. It costs me more to run the engine/generator for gas at $3/gallon if I run out of battery power. And I have two 75W solar panels to provide a charge to the house batteries when not plugged in.
