Batteries, AMP ratings

[Pete & Cynthia]

I have a 2002 34' FDDS and am getting ready to replace the house batteries. I can not find the original ratings for those batteries. The batteries in there are the Interstate Workhorse 6V, but I can't find the AMP rating...any help would be appreciated.

Most likely they are the standard 6 volt golf cart batteries, which would have a amp-hr rating of around 220. I had Interstate Workhorse batteries in my '04. I don't remember the model number right off, but they were 220 amp-hr.

Thanks Jim, that helps.

Pete, my 2004 came with 4 0f the Interstate 6 volt "WORKAHOLIC" deep cycle part # U2200 batteries.

They are BCI GROUP GC-2, 232 Amp Hours each.

Go to the bottom of this link's page to see the specs on them:

Pete, I replaced the 6 that the 2005 have with Interstate U2200's. I believe the next step was U2400's but I believe size was somewhat of an issue and so was price. I still have this habit of changing batteries every three years.

For some reason the math isnt adding up here. Since we are operating at 12v Vs 6v, do you have to divide the amp/hrs by two for a 6v bat being used in series to support a 12v system? I recall setting my Xantrex inverter/charger at 630 amp/hrs based on six U2200s @ 105 amp/hrs each....I guess if you stay in 6v ratings, you get an "apples to apples" comparison... Also think Interstate offered a U2400 that provided 120 amp/hrs--this bat was lightly taller in dimension. The U2400 isnt on the Interstate table in above posting.

When you add batteries in series, like you would do with two 6 volt batteries to get 12 volts, the amp-hours does not change. When you add in parallel, then they add. If you connect the 6 batteries as in our coaches, you will get 660 amp-hours. Three parallel sets of two 6 volt batteries, 220 amp-hours each set of two, for a total of 660 amp-hours.

If you connected six 12 volt batteries in parallel, then you would get the 105 x 6, or 630 amp-hours.

And if you add 6 Lifeline AGM batteries, you will get 660 amp hours -- 110 amp-hours per battery.
