Car Forum / Driving, Maintenance, Tuning / RVs / September 2005U2200 battery box
I have just replaced 2 12 deep cycle type 24 batteries with a couple of U2200 6v batteries. Of course, the exisiting (type 24) battery boxes are not deep enough for these batteries. I assumed that it would be no problem to find boxes to fit. After a couple of hours poking around on the Internet, I think may have been overly optimistic. Anyone have any idea about where I can find boxes to fit u2200 batteries? These seem to be difficult to obtain. I made my own using and old cooler and PVC pip and fittings for venting. (I have them in my house connected to a solar array). It works out nicely as the plastic cooler is insulated and provides protection from acid spills. Also saves the environment from one more old cooler into the dump. Ed >I have just replaced 2 12 deep cycle type 24 batteries with a couple of >U2200 6v batteries.

A bit off topic but how long can GC batteries sustain a 50 amp drain without damaging the battery? I ask as I'm trying to set up an emergency power system to run O2 concentrator for a neighbor. > how long can GC batteries sustain a 50 amp drain > without damaging the battery? That depends on the capacity of the battery. It would take many cells to withstand such a load for much time, for sure. > I ask as I'm trying to set up an emergency power > system to run O2 concentrator for a neighbor. In that case, the battery wouldn't last nearly as long as a couple or three cylinders of oxygen. Besides offering general mobility, isn't a power outage one of the prime reasons for an O2 user to have a few cylinders on hand? A small generator (not necessarily of the camping/quiet variety) would cost less than the battery and associated inverter system required to operate the average concentrator for more than an hour or two. JR An "E" cylinder (about the size of a small fire extinguisher) will last 140 minutes @ a rate of 2L/min. I agree with your generator statement except it should be a quiet one/camping variety.

(Read Honda). One concern with gen sets is the difficulty of the target populace to manage to start/fuel one safely. I'm making an assumption that your neighbor is elderly 70+ yrs. This is why a solar powered system would be better (quiet, no physical exertion to refill/start but more expensive). I planned on adding a solar back up as a priority back in 1999, I paid $1000 for the 4X45W panels and scrimped on the inverter ($28 400W) and batteries (one used ((free)) and on I bought a HAM feast. Amateur radio) for $30 and the cables from Wal-Mart (49" black lawnmower battery cables 6GA with lugs. $2.22 each and some yellow electrical tape to ID it as positive and an old cooler (failed thermoelectric cooler project) to hold the batteries. If you want pictures LMK and I will email them to you BTW: I live in a large city so my panels are fixed flat at the sunniest/most convenient and safest from theft place I could find. All trade offs on efficiency.

All trade offs on efficiency. Right you are on the neighbor's age. Interesting man, once worked in the space program and did a ton of the design work on the explosive separation systems for space craft. My son, my wife and I are active in hospice and other service groups that put us in contact with a lot of folk with very interesting life stories to tell. If only half the *war stores* are true they sure making interesting listening regardless. I've sent you an email back channel on the assumption your addy is functional. I'm talking with one of the local volunteer equipment providers about their being the contact point so that as the need for the equipment is passed the family can donate to the NP/NGO so that others can benefit. Most O2 concentrators consume 400-500W (4-5A@110V) but require 3-4X the power at startup. I calculated 33.4A for an 4.0A invacare model, I know it is still high demand. I would think that you would want at least a 24-36 hr supply/run time. So 35A(inverter inefficiency) X 24 = 840Ah One set of golf cart batts proved ~220Ah, so I would go with 5 sets of 2 or 10 golfcart batteries @ about $50-60 each you are looking at $500-600 in batteries not including cables to tie together and the cost of an inverter capable of handling the load at least 1000W probably 1500W also, some cheaper inverters (MSW) have difficulty with capacitive loads, this can be solved by running a inductive load concurrently (i.e a low wattage light bulb). All said and done I would estimate total cost not including instillation about $750 including a 120V battery charger, no solar or gen. I use a CPAP and it draws about 1.5A @ 120V or 180W 8-9hrs/day = 15A X9hrs= 135Ah. I have 180W in solar and 180Ah of battery bank.

If the U2200 is the typical 'golf cart' battery, take a look at http://www.bluesea.com - they have a battery box designed for golf cart batteries.

Alan Take a look at http://www.quickcable.com/57.html for single golf battery box. >I have just replaced 2 12 deep cycle type 24 batteries with a couple of >U2200 6v batteries.
