Batteries - simple question

So, in reality, you WILL pay MORE for AGM and GET LESS capacity for the SAME BATTERY SIZE and will not get any longer service life.

I myself have never understood why some one would buy an AGM for a normal RV setup. up here they are more like 50% more expensive and as long as you have a vented battery compartment why spend the extra?

Other than

1) Less self discharge
2) Never add water
3) Lower internal impedance which makes them better at driving higher current loads like inverters with lower voltage drop.
4) Because of the lower internal impedance, they also charge faster than an FLA battery

I use them in both my boats mainly because of the self discharge characteristics.
