The Following are important considerations for battery installations
*Batteries should be mounted higher than normal bilge water levels in a battery tray or box that is impervious to battery acid.
*Ventilation for battery compartments should be at the top of the compartment and separate from engine ventilation.
*All batteries should share a common ground connection with cable gauge equal to the largest power supply wire or starter cable. This excludes batteries that are isolated from primary systems.
*No battery in the boat should be used to supply power for dockside equipment (ie boat lifts).
*No more than 4 ring terminal should be stacked on a stud. Accessory studs should be used as needed.
*Never use a wing nut to secure terminals. A recommended method is to use a stainless steel star washer below the ring terminal with a stainless steel nut on top.
