Battery and Solar woes
Long read, so grab a coffee... Rockwood Mini-Lite 2306. We’ve had this generic 100W flexible solar panel which has served us well for several years now. I hate drilling holes in the roof of my RV to...

An update....
I took both T105's out of the RV this morning. One is on the Shumacher 6V 6A charger, the other on the NOCO Genius.
Shumacher showed about 4 amps of charge-rate at the beginning (about 2 hours ago) and has since fallen to below 2A.
SG reading is 1275 on all cells, so we seem to be making progress....cautiously optimistic so far.
I haven't taken any readings on the NOCO battery as it has a maximum 2A charge rate and is currently in "maintaining mode" with the green LED pulsing.
I will probably leave that one until this evening at the earliest.
As I overcome one problem, I start hypothesising about others....maybe I had "enough power" last year because the batteries were so new and we definitely had more sunny days than this year...it has been a dismal Spring and unimpressive Summer so far, in terms of hours of sunshine.
Both "chargers" you are using are toys, it will take weeks to months to fully charge those T105s and even then, I doubt they will be more than 98% charged..
Your "converter" in your RV should be capable of at a min of 35A which will speed charge your batteries compared to those pea shooters provided the converter is capable of switching to bulk charge mode of 14.4V.
You are safe to keep both T105s in series for 12V charging, there is no need to break them apart like you are doing unless the cells clearly show discrepancies in the specific gravity reading between the two batteries.
Nothing like doing things the hard way :S
