2001 LXi Battery Failure

[Urnie-Medie]

Hopefully some one can help. My engine batteries are bad after less than two years. They said they are burnt up - hot and smell like rotten eggs. I talked with the battery company and the batteries had a 18 month warranty and they failed in a little less than two years. They asked if I keep the motorhome plugged in all the time and I told them yes. Several on this forum have told me that this is the best way to get the maximum use out of the batteries. They said this is a common mistake and when not in use the batteries should only be plugged in about one week out of four months of storage. I was also tole to keep the switch on that ties the coach and engine batteries tied together.

Please let me know if I am doing something wrong. I am open to any suggestions.

Thanks
