They were installed on their sides with a bit of a modification to the base plate and addition of some painted sheet metal to protect the terminals that are now horizontal. Longer tie down straps too. Not cheap, but I was told that the six volt batteries will last twice as long as the 12 volt. So far so good.
Thank for the info. I will put it in my file for when I have to replace my current batteries. AGMs certainly should last a lot longer than lead acid, especially because they take the shake, rattle and role of RVs much better. I found that in my boat. The only thing that has me a little worried are the recharging parameters. AGM battery manufactures want you to have a converter/charger with am AGM mode since the charging parameters are a little different. Itís good you have all AGMs but that WFO converter is probably not doing them justice. My PD4655 says it will charge AGMs but dies not have a switch to change to an AGM mode. If I decide to switch, I will have to check with Progressive Dynamics and see if the PD4655 will charge AGMs effectively. Thanks again.
