Lifeline batteries for RV and Marine are the kind that you can really shove the current to them if you have the proper charger.
My 100ah lifeline is over 7 years old and it sees 60 amps when discharged down to 60%soc. and stays over 45amps for well over 45 min... I have used a Progressive Dynamics 9260 for about 10 years now... I do have 200watts of solar to charge when on the road.
I am running a total AH using my trimetric... Currently over 5000ah cycled since my lifeline was installed.
UPG, Universal AGM 100 ah batteries state right on the battery not to exceed 35 amps..
I tested one in real world testing and it died in less than 2 mos.. I was told that disregard the 35 amp thing, use your 60 amp charger and have at it.

Charge Method (Constant Voltage) Cycle Use (Repeating Use)
??????????????
Initial Current 33 A or smaller
Control Voltage 14.6 - 14.8 VFloat Use 13.6 - 13.8 VControl Voltage
Terminals
So I think buyer beware...
Everyone I know that has lifelines are happy campers...
