How much converter/charger is really needed?
I have a pair of NAPA 9824M Marine/RV batteries with a 20 hr rating of 79AH each, wired in parallel. Is there, really, any advantage in going from a 45 amp (PD4645V) converter/charger to a 55 amp (...

I will add.. Even if you upgrade the batteries (Which I'd do on a replacement basis by the way. No need to pull good batteries out) UPGRADING the converter (and the wires to/from the batteires and the fuse or circuit breaker) only makes sense if you boondock and re-charge off Generator a lot. and then only if the Genny has the OOMPH..
Now earlier I quoted Xantrex
This is from Trojan (Battery folks) they suggest a 10% C/20 rate for longest battery life.
SO where as my OEM Interstates lasted 9 years.. Had I had a smaller converter they may have gone 10 or 11.. I'd not upgrade less you need it.
ALternative.. The original setup here I had and 80 anp converter (bit big for a pair of GC-2) and a 100 amp inverter/charger (2000 watts A/C or 100 amps DC) I upgraded the bank and when on shore power I used the converter ... Still do. but when boondocking used the 100 amp charger in the inverter for less Generator time. (I have over 500 amp hours of battery).
Worked great.. Till the inverter crapped at about 13 years of age. Now I have an 80 anp inverter/charger.
