ptomacbass Posted February 2, 2009 Posted February 2, 2009 What type of charger do I need to charge two 12 volt deep cycle trolling motor batteries at once? Quote
Super User Wayne P. Posted February 2, 2009 Super User Posted February 2, 2009 Well, I charge three 12V batteries at once with a 3 bank Dual Pro Charger. I also charge three other 12V batteries at the same time with three separate 12V portable chargers. If you have your two batteries connected in parallel as several on this site have advised against, then any single 12V charger will charge them both eventually with the highest capacity charger taking the shortest time. If you use them separately or as a 24V series hookup, then you can do it like I do my 3 battery setups. You can charge them with a 24V charger if they are connected in series also. Quote
jim payne Posted February 2, 2009 Posted February 2, 2009 How often do you fish and how are the batteries hooked up? Quote
Calcutta Posted February 2, 2009 Posted February 2, 2009 When Im done fishin I connect my crankin battery and my trolling battery with a homemade set of wires and alligator clips.{sorta like mini jumper cables} I then use a plain ole battery charger on trickle charge overnight. Ive done this for several years with no problem. Quote
jim payne Posted February 2, 2009 Posted February 2, 2009 I have been doing that for ten years with a single charger or off the truck too. Single charger will work fine if it is a good charger. Quote
stormrider Posted February 3, 2009 Posted February 3, 2009 I do mine seperately with Battery Tenders Quote
