Learn About the Different Types of Marine Batteries

Did you know...
Deep cycle batteries come in both AGM and lithium chemistries.

Deep cycle marine batteries feature a heavy charge and discharge cycle, making them perfect for long-lasting power on fishing boats, kayaks, and any other watercraft using a trolling motor or electric motor.

If you're operating a live well pump, depth finder or fish locator, a deep cycle marine battery generates the reliable, durable energy you need.

Deep cycle, or deep cell batteries are designed with fewer, but thicker plates, which means they can be discharged at a consistent rate for a longer time, at a higher depth of discharge.

It also means they can withstand high temperatures while providing high electrical currents. Deep cycle boat batteries can be drained and recharged many times; starting batteries can't. That's why they're typically used to power electric motors, and other applications, too.

Marine Battery Care & Maintenance

It won't work if it's not cared for properly, especially in the off-season.

5 Simple Steps to Prolong the Life of Your Marine Battery

  1. Keep track of your battery status. Monitor its state of charge/discharge and never let the charge fall below 50%. Letting batteries fall lower than a 50% charge regularly will dramatically reduce the life of your battery. If you have an X2Power Lithium Bluetooth boat battery, you can monitor it on your phone.
  2. Choose an adequate battery size for your needs. Using a battery that is too small will force the battery to use more power than necessary and reduce the usable life of the battery.
  3. Minimize your power demands. Arguably the most inexpensive way to increase life expectancy of your battery is to turn off unnecessary electronics when not in use, like fish finders, lights (when not necessary), etc.
  4. Add an alternative energy source like solar panels or a wind turbine to help keep the batteries charged to optimal levels.
  5. Equip a smart charging regulator to create the ideal charging environment to charge the battery with the boar’s alternator.

Tips For Maintaining Your Boat Battery

  1. Get your current battery tested - Have your battery tested for free at Batteries Plus, especially if you've had your boat in storage for a season or more.
  2. Get yourself a battery box - Use a battery box to minimize the impact of vibration and also to keep your battery secure. (Note that sometimes they're required by law.) An unsecured battery can cause damage to both the battery and your boat.
  3. Keep connection points clean and electrolyte levels up - If you notice corrosion on your battery terminals, clean it up with a mixture of baking soda and water. If your boat carries a flooded battery, monitor the electrolyte levels before charging or operating your boat.
  4. Waterproof chargers for the win - Waterproof chargers are perfect for your time on lakes, rivers or other waterways; you'll never find yourself on the water with a dead battery.

Note: Choose a charger with a high enough amperage for your battery. The Duracell Ultra Automatic and Ultra Marine chargers are good options.
