By definition, the batteries you describe serve a dual purpose which serves well for some dual functions, but in the context of the discussion; it is stated the Pure AGM Deep Cycle batteries will not only outperform in House Battery applications, but last 3 times as longer as it maximizes lifetime and cycles.

If you think about it, a battery designed to serve the needs of starting an engine and maximize the AH capability to deep cycle tend to have different objectives. i.e. my batteries don't have the automotive posts because they are NOT designed for cranking engines. Sure they could in an emergency situation with the Coach's switch.

To further hammer that point, I replaced 2 perfectly good Dual Purpose NAPA RV/Marine FLA batteries to not only get maintenance free, but for 125ahs each, and 3 times the normal life or cycles. I paid around $500 and I insist it is the best thing I have done since buying the RV. There are several brands that make the same thing; so I will not advocate the ones I bought, but simply say, if you can get Pure AGM Deep Cycles anywhere close to 125ah each for about $250/battery you are doing good. Note: This is NOT to say that other batteries are bad, because someone could take the batteries you suggest and do just fine. I am just trying to relay the difference between the Pure Deep Cycle and what was meant by other poster.

Hope this helps.
