12v batteries reading 14.18v
Yep, it's me, back with another question :-). I double checked the voltage with a second voltmeter, and checked the first voltmeter on another battery. It seems that the 14.18v is reasonably accura...

A 12v battery reading 14.18v open circuit, rested, 18 hours removed from the charging source @ 50 degrees F, is not right.
I've no experience with Gel batteries but I expect I would have read something about their incredible surface charge retention, if it is actually true, in the 2 decades I've been reading about lead acid batteries and experimenting and collecting data on their performance.
What one mostly reads on gel batteries is their incredible cycle life when charged properly, and their premature death when not charged within their well published parameters.
Don't praise your charger yet, see how the batteries perform the next time.
As I said every time I noticed well above normal surface charge retention with my flooded battery, some of the cell's plates were exposed, and once refilled properly That voltage retention ability was erased along with some portion of the battery capacity, never to return. I imagine voids in gelled electrolyte could do something similar as low electrolyte levels on a flooded marine battery.
Get a clamp on ammeter. Guessing sucks and actual numbers/data rule.
