I am about to change out my six house batteries, the original ones are Interstate wet cell, I am replacing them with the Blue Optima AGM. Since I have owned the Rig, about a year and a half, I have looked at but not messed with the Magnum Controller, it has a dial, inverter on off, a few other buttons, and a LED read out that usually says FLOAT CHARGING. My Question, after changing the batteries do I need to adjust anything on this contraption? I have read somewhere about level settings for different batteries, thanks, G

When we changed from wet cells to AGM, the dealer did change the charging profile. Can't add anything else. I would contact the battery company or the charger manufacturer. Good luck,

Yes, the charger needs to be told that you have AGM. It knows what to do after that. We install Magnum inverter/chargers in our yatchs and have to program them. If you have the manual its fairly easy.

Yes you need to program the inverter or the AGMs will not be used to their full potential and will not last as long. Dealers being incompetent on these issues does not surprise me since when dealer replaced my inverter some years ago they left it on factory defaults, 200AMP-hours of Gel batteries, which would have killed my batteries quickly.
Why Optima instead of Lifeline? I would check the specs against the equivalent Lifeline and compare prices. Lifeline's have been well proven in RV situations. I have used them since 2003 in two RVs and am a very happy customer.

Thanks, I looked in the manual and it looks pretty simple to reprogram for AGM, as far as Optima, I read some good reviews on them and new someone who had accesss to them and passed on a nice savings to me. G
