If you had two types of battery which type would you use for your house vs chassis?
Maybe this question is dumb but I have two RV / Marine batteries and I just invested in two AGM batteries. So which location would be best to install the new AGM batteries? House or Chassis?
I think I know but I would like some opinions from you all. JR

First of all the RV/Marine batteries are most likely not true deep cycle and should really be used as a starting battery, aka chassis. You can verify this by checking how they are labeled; if they mentioned cold cranking amps it is not a deep cycle.
What type are the AGM batteries, are these true deep cycle, again check the label. Deep cycle batteries always are rated in amp-hours, not CCA.
House batteries should be deep cycle

Most AGM are best for house batteries. They generally are designed for deep cycling. Some are designed to be starting batteries in that they can withstand quick, heavy current draw as needed in starting a vehicle engine. It really depends on the type of battery you purchased. If they specify 'cold cranking amps' and the numbers match the need of your engine, use them as a chassis battery. If they specify 'RC' or reserve capacity, then they might be designed to be deep cycle, offering output for longer period of time than starting batteries.

House, but don't make the mistake and use the old ones as starter batteries if they are labeled 'deep cycle' you will be disappointed, for that you want starter batteries with high CCA (Cold Cranking Ampere) value.
Deep Cycle batteries allow for a higher discharge rate but don't have the initial 'oomph' to crank over the engine.

That was my take but I wanted a second opinion. JR

AGM batteries are also made for statring batteries.

Correct, often used in ATV/motorcycle/marine applications not to common in automotive though.

Many BMWs and other high end autos use AGM start batteries. Also used in off road use since they can be in any position. That's why in my first answer I hedged my advice as depending on what the batteries were built for.

I have an AGM starting battery in my 60 Corvette. It has been in the car for over 10 years and is still going strong. I do keep a trickle charger on it.

RV / Marine in the chassis, AGM in the house.

Here is a link to some facts about batteries that you will
find very helpful, there is a lot of misinformation floating around.
