A float voltag of less than 13.8V seems to boil off fewer batteries. I usually run about 13.5. If the charger bulk charges to 13.8 and then switches to a lower float voltage I wouldn't worry. Give it a bulk charge before use.
There's a chance that one or more of the blue resistors set the voltage, they are high precision. R7 and R10 appear to have been running a bit hot. It may be worth checking their values.

I'd guess they are 222Ξ© and 182Ξ© but I'm not entirely confident of that. If they are just ballast resistors for the LEDs you can ignore them, unless the charger is using one or more of the LEDs as voltage references.
