My Endurant deep cycle battery has, in addition to the standard type connectors, two smaller threaded vertical posts with hex nuts on them.
Is there any reason that I should not connect my 3 stage battery charger to these posts? (The spring clips fit them more easily)
The reason I ask is that the chrger is still showing "boost" stage, 6 hours after first being connected. I would have expected it to have moved to "charge" by now

Mark, if the threaded posts are physically on the same posts as the main terminals then no problems.

The 6 hrs on boost sounds like something is amiss.

I had a similar thing happen and just turning the charger off then on , sorted it . But you had some other issue with the batteries earlier didnt you? Maybe a trip to the batt shop for a load test is in order.

I'll try "resetting" now and have another look in the morning. Battery should still be fine: it has been hardly used since the last test and has been kept pretty well charged (see - I am learning )
