I searched this and decided to change my profile to the higher settings:
14.8V Charging and 13.6 Float.
This is up from :
14.7 and 13.4.

I have not been using water, and multiple posts mentioned that flooded lead acid batteries would benefit from the higher profile.

That said, this is my first multistep charger: ProMariner 1250P.
(which replace my old two-step Promariner that finally died).

Your opinion appreciated.

1. What does the maker say is optimum for your specific batteries?
2. Is your charger temperature compensated, so it won't exceed maxes?
3. With a calibrated voltmeter, are you getting the same voltage at the batteries that you have programmed?

1. 6 volt wet cells from Costco. Good question. Nigel Calder, as I understand his book, says between 13.2-13.6. I decided to raise to the upper end based on no usage of water. It is the primary profile from Promariner, the 13.4 is the secondary.
2. Yes
3. Great question! I will definitely check it.
Thanks.

Thanks Rain Dog.
I have some reading and checking to do. Thanks for the source.
After checking and veryifying the charger voltage at the battery (thanks hellosailor) I am going to consider a custom profile based on the chart you provided.
For now, I am going to change back to the lower float profile.
