Installation And Maintenance

Exide batteries should always be installed in a ventilated area. Batteries release explosive gasses during the charging phase and should not be exposed to spark or flame. When installing a battery in your boat, it is important to use either a box or a tie-down system to keep the battery stationary once underway. This will reduce unnecessary vibration. Make sure all connections to the battery terminals are tight. Additionally, it is important to coat the terminals and connections with a corrosion inhibitor. The corrosion inhibitor should be reapplied every several months. Failure to do this will result in poor connections and wire corrosion, especially in salt water environments. Corrosion increases the resistance in the wires, requiring more amps to be drawn to run electrical equipment. When installing a new battery, be sure to remove any plastic battery terminal protectors before attaching wires.


All Exide marine batteries, except AGM types, have removable vent caps so that electrolyte levels can be checked regularly. You should check the electrolyte level every month. When storing a battery for the winter, check and fill with distilled water as needed, recharge the battery fully, and store in a cool place. When preparing the battery after winter storage, recharge the battery to its full charge state.

Selecting The Proper Exide Battery

Exide manufactures a complete line of batteries for all marine applications. From personal watercraft to mega yachts, Exide has a battery for your needs.

Marine Starting Batteries
Marine starting batteries have been designed to deliver high bursts of power for short periods of time, to start marine engines. The power level you need depends on the cranking requirements of your engine. Marine starting batteries are not designed to provide trolling or deep cycle power, which requires plates built to different specifications.

Dual Purpose Batteries
Exide manufactures a line of dual purpose batteries which combine deep cycle capability with starting power. They deliver enough power to start a 350-hp engine and provide at least 7 hours of continuous 10 amp 12-volt draw.

Deep Cycle Batteries
Deep cycle batteries incorporate thicker grids, denser active material on the plates and alloys specifically designed to provide many cycles. These batteries are designed to provide continuous operating time to run trolling motors, live wells, inverters, 12-volt lighting, depth finders, etc. They can be charged and recharged many times without damaging the internal components of the battery. These batteries have a lower MCA rating and higher reserve capacity/amp hour rating than dual purpose or starting types.
It’s Time To Replace Your Battery When.

• You had to jump start your battery.

• The battery can barely turn the starter over.

• Lighting and electronics dim or go out when starting.

• The battery will not hold a charge.

• The battery becomes submerged.

• The battery discharges frequently between use.

• You buy a used boat.
