I have a 2007 tour with a three batteries bank each 120 amps hours the problem is the first battery needs water added all the time and gets hot the other two don't I have check charger and connections. this is my second set of batteries in a year any suggestion

Show us a diagram of your connections.

We also need to know what you are charging these batteries with. If it is a CONVERTER/CHARGER we need to know the model number...I also don't know what a 2007 TOUR is as well...Roy Ken

These 3 batteries.......all of them are 12V (not two 6v and one 12V?Are batteries all the same age/size/amp hour?Are positive and negative cables coming off of that first battery?Better load balance/charging is for positive off one battery and negative off of other battery at end of bankRoyB wrote:I also don't know what a 2007 TOUR is as well...Winnebago Class A

What Old-B is trying to say is if both the + & - leads come off on the same battery, not like his diagram you will have the problem you posted.

the batteries are all the same size 29HM 225 mins @23amps all neg are tied together and pos tied together with one pos tied to first battery and neg tied to third battery the charger is a inverter/charger three stage there is another set of cable that are connected just opposite of the first I'm thinking this is for connecting the coach batteries to house 2007 winnebago tourThank

Need to remove, separate the batteries to be charged and tested.
I think you have one bad battery.

Second set in a year? Something is really wrong. Could be just a defective battery. Just have it replaced under warranty.

I don't know why Winnebago does this.....put in three 12 volt batteries on their DP coaches. If you end up with a bad battery, you'll need to replace all three as mentioned above. This would be a great time to take measurements and install four six volt batteries. You'll be better served. I know that on my sister's Winnebago (Itasca Meridian). there was room for four six volts where the three twelve volts were located.

If you put in 4- 6 volt batteries and just one has a defect later on, you STILL REPLACE ALL 4 BATTERIES. Having 2-3-4-5-6-7-8 batteries does not change this. Interstate Battery, replaces ALL batteries in a bank if just one has a defect under warranty. Doug
