Our house-batteries get a pretty decent workout, because most of our camping is boondocking. Over the past several trips, however, our Trimetric has indicated a lower SOC in the morning than what I normally see (65-70% vs. 75-80% SOC) despite fairly common consumption. I'm pretty sure they were also taking longer to fully charge, but I never actually measured that - I'm just real familiar with their behavior.
We have eight 12 volt AGM house-batteries, six of which are a little more than seven years old. I added two additional AGMs to the house bank about a year and a half ago, and I'm pretty confident that those two are still in good shape, but it's time to replace the six original house-batteries.
Man I really wanted to go lithium. I read more battery reviews, studied more battery specs and read more opinion papers than you could shake a stick at, but in the end, I stayed with AGMs. It just came down to the initial cost - plain and simple - $1800.00 for six new AGMs (for a total of 840 AH with my two good batteries) or $7500.00 for six LI batteries (for a total of 600 AH.)
I had some other minor concerns, but had the price been more palatable, I'd have made the leap. There are a lot of benefits to LI batteries - especially for boondockers with solar. If we still own this RV in seven years, I'm quite sure the price of LI will be significantly lower, or maybe they'll have RV fusion reactors figured out by then.
