I hve problems with my Delphi batteries, hve bought new last year in
Italy 115 ah. Hve to charge after max 25AH when batteries without load
is at 24 volt. I believe the charger is not charging high enough. My
24volt/50ah charger charge at max 28,5 amp and batteries will not be
fully charged. The instruction book for the charger in French and
difficult to understand. Now in Preveza, Greece . On my previous boats
the batteries normally lasted for 6/8 years without problems.
