El Randero once tried to tell me 2 depleted group 31 plTP AGM batteries could not accept more than 75 amps, when a 100 amp model was ordered.
When the real 100 amp 'boondocker' arrived, which was physically larger to boot, surprise! They could accept over 90amps, and could for close to an hour before tapering began.
If I wanted smoke blown up my A$S I'd get a cigar and a garden hose.
Trust if you want to, but believe only after verification.
You want a Powermax, skip Randy, go right to Errin @PM, and tell him what Absorption voltage you want, if not 14.4.
Dont try and ask for a digital timer though.
