PD4655 Charging Graph
I have been reading quite a bit about different converters and charge rates, specifically some claims that PD's seem to drop off earlier than other brands. That is not what I have noticed on my setup,...

Nothing in life is "free".
Absorbed glass mat has specific characteristics. They have been discussed above.
There are just too many permutations to try and round this down to a single sentence.

An individual wishes to pay two to three hundred percent more for absorbed glass mat, they should have a list of ideas why they wish to do that.
For instance the VRB would be a clear leader in powering high amplitude short duration loads like a microwave. But the VRB would conversely be a clear loser in the weight versus ampere hour category.
How do you determine that you are taking care of an AGM correctly, before it fails? Not every RV is a science lab. Most RV owners do not have the ability to log kWh transactions. "They lasted 8 years" is meaningless when it comes to a different individual.
I am not criticizing AGM, merely trying to establish some perspective here. For crying out loud, the subject of how to equalize a flooded battery has only been recently augmented on this forum. Top charging seldom mentioned. Folks are basing a lot of opinions and conclusions on batteries that have been mistreated, or worse yet, on inferior battery brands.
For a different twist, let's compare the TOTAL performance and lifespan of a Lifeline battery versus a Rolls or Crown battery.
I've got news for some of you. Maintaining a VRB to achieve max amp hour capacity is a hell of a lot harder than it is with a flooded battery. Do some 20 hour tests on 5 year old AGM batteries the average RV owner has maintained and see where you are.
You find a 2 year old absorbed glass mat battery with 82% of the capacity of a new unit. What do you do? Explain it to me...
