Q:I have an '09 Seadoo 255 and use a battery tender on my Skidoo and Harley and a vehicle or two, but was told to not use a tender at all on a jetski. I did put one on last year when I first got my Skidoo not knowing that I shouldn't have and when I checked after a day of having the battery tender on the wires were hot. The service manager explained that since the body of the jetski was not metal that it could not use the body as a ground therefore causing an overload on the sensitive circuits, ie. damage. I was lucky, so I am confused as to whether or not you all are suggesting that it is ok to connect the tender with the battery in place or is it understood that the battery should be removed each time before attaching the tender? Mine is in the garage now on a tender, but that is because it has been a long winter and the battery was removed before attaching the tender. What is the story with your particular product for proper use on a jetski? Thank you, JoshuaAsked on 4/28/2011 by Joshua

Q:can this unit be used to charge more than one battery at the same time?Asked on 1/31/2010 by new boat owner from el paso texas
A:Not to my knowledge, it is a low amp trickle charger that can be ordered with either clips or ring connectors.
During the winter, I remove batteries from boats, and bring them indoors. I rotate them to trickle charge with a unit like this while they are dormant to keep them conditioned.
Pro-mariner does make larger 3 phase units that can charge 1,2 or 3 batteries at the same time and these larger units start with a high amp charge, then desulfite phase, then trickle charge. They are great as on-board chargers for the regular season. It is best if you have multiple batteries to have them all the same type (ie: cranking, deep cycle, dual purpose.) the larger pro-mariner units can be used with wet cells, AGM batteries as well as gel cells, they just all have to be the same type. You set the charger accordingly.
Hope this info helps you out.Answered on 2/9/2010 by Capt. CJ from Connecticut
Q:The battery manufacturer (Deka) recommends "never" leaving a trickle charger on the battery over 48 hours. The specs on the product above state it can be left on batteries indefinitely. Which is correct?
Thanks!Asked on 12/1/2009 by duck from bowling green, ky
A:Well the thing about pro mariner chargers and maintainers is one you get into the larger size units, they actually switch themselves off or maintain mode and are technically not charging the unit. I would not "always" have my battery actually charging either. I would want something that flipped off or into maintain mode.Answered on 12/4/2009 by Bryant from Tech
