  • charging batteries

    Ok I have connected by 2 12v batts in parallel (pos to pos and neg to neg) to give me a little longer running time for my 12 v trolling motor. my question is: When charging can I connect my charger pos clamp to one batt pos post and the neg clamp to the 2nd batt neg post to charge both batteries at the same time? Or do I need to charge each battery seperatley? i hope that made sense....

    seperatly......

    BTW
    I have only seen two 12vlts wired to a 24vlt ..... did'nt know you could wire it your way, as I was told to never touch positive to postive. ....

        You can charge both batteries at the same time, will not hurt a thing unless you have one battery go bad like on a diesel truck,they run dual batteries & both get charged at the same time. If you have one go bad, it will draw the other one down,thats about it. You can hook charger to one battery & it will charge both.

          You can do it just as Dawg says but it will take twice as long.

            You can run 2 batts in parallel for 12v safer / easier to disconnect one then the other via perko switch

              Been doing this for over 20 years. Not a problem. It's best if both batteries are the same age and have had the same use. Don't want one dragging down the other. I've got 4 connected in parallel for super-long run time.

                  Yep-can charge both thru one. Parallel is fine-Dawg and Coe are 100% on.
