It’s a no Brainer, Always Use the Right Battery

For the umpteenth time, your marine should always run on a dedicated battery. The absence of such is a recipe for unwanted situations deep in the middle of the lake. Having the right battery will keep your boat running for 4-5 years.

Temperature & Humidity

By now, you should know that your boat’s battery should not be exposed to conditions that are too hot or too cold. Such conditions often provide a conducive environment for the battery’s plates to shed or flake, especially during charging cycles.


When not in use, the battery will discharge over time. How you store your marine battery will have a bearing on the rate of discharge. If the storage conditions are unfavorable, this might be reason enough to affect the battery’s life expectancy.

Proper Charging

A battery’s life expectancy can be shortened if it is either undercharged or overcharged. Just so you know, an undercharged battery is a catalyst for sulfate hardening. Overcharging deprives the cells of the much needed electrolytes and this leads to overheating.

Poor Maintenance

If your marine’s battery is poorly maintained, it will hardly live up to its full potential. There is no room for shortcuts on matters of maintenance whereby you might opt to overlook the essence of distilled water. Also, not cleaning your battery as often will reduce its lifespan. 

 Your marine’s battery life is a culmination of several factors. By keeping note of these pointers, you will save yourself the agony of purchasing a new battery. Do not fall short of giving your battery some tender, loving care because it will definitely love you back.

 Nonetheless, the only possible way of expressing love for your battery is through some maintenance routines:

  • Storing the battery in a cool, clean and dry place
  • Testing your battery as often
  • Always being on the lookout for any signs of corrosion

 Long story short, how long your marine battery will last will boil down to how well you understand this critical component. A little bit of diligence and due care will always ensure that your boat is roaring to go again. All said and done, you can only prolong your marine’s battery life if you keep yourself apprised with some simple rules and guidelines.
