I’m not exactly sure what the specific issue is ... just that is the connection requirements specified in the manual.

What is the problem with the pro sport charging 2 batteries on a single bank? I always try to keep identical batteries of the same age on the house bank. I know there is a phenomenon where 2 batteries on the same bank will only charge until the first battery is fully charged, but usually keeping the batteries of the same age and model will minimize this.

And if you start looking at AGM batteries,while the standard AGM and flooded battery charging profiles are the same, ‘premium’ AGMs can’t be mixed with ‘standard’ AGMs or flooded. Charging profiles can’t vary between banks with the Pro-Sport. Another oddity .... if you have a 2-bank Pro-Sport then max. of 2 batteries total (1 house, 1 start). If you have a 3-bank Pro-Sport then max. of 3 batteries (2 house, 1 start). In other words, each battery must be connected by a leg of the charger. Finally if you have a battery combiner, disable it when you are on shorepower (many, such as the Blue Sea, can be turned off via a switch or relay mounted in the ground wire ... but many can’t be disabled!). Disabling the combiner is a best practice due to the distributed charging scheme programmed into the Pro-Sport.

I think i will get the surettes load tested and decide whether or not to replace after that and replace the starter battery with a group 24 (if it fits). We are also hoping to do more cruising and spending time on the hook, so we are looking at get set up with solar as well.

I was thinking they were near their end of life but a battery equalization last year seems to have given them a new lease on life. We replaced a Rolls starting battery after 11 years.

My first instinct is to replace the deep cycles with Interstates and upgrade the 22NF to a Group 25 Marine Starter Battery in proper battery boxes (I have seen first hand how quickly a dropped wrench landing on exposed 12v battery terminals can go very bad). The charger is a relatively new looking Professional Mariner ProSport 20 Heavy-Duty Marine Battery Charger. Both banks are monitored by a cruising equipment company e-meter. My questions are 1. Does anyone have 2 G27s and a G25? Is there room? 2. Someone told me the Surette are very good batteries with longer than average life and I shouldn't be in a hurry to replace them. Experience ? Thoughts? 3. Anything else from your experience I should be thinking about?
