Yes lifeline it'd the only one that says you can use a rely high rate of charge
That does not mean exactly the same thing as "charge faster"
I have four large AGM batteries in my drivers side bank
From my experience, when disconnected and charged as a separate bank, using the same 40 amp vector charger, they come to full charge faster than the equal amount of flooded batteries, there charging is more efficient
No I don't preform discharge~ recharge cycle tests
This is simply an observation from daily use, with periodic individual bank maintenance
