Batteries need proper care and maintenance to function properly. That’s especially true of marine batteries, which are subject to certain stresses and operating conditions that can make them wear out and develop problems such as corrosion if they are not properly cared for. Whether you’re planning to store your boat before winter or you are just taking your boat out in the spring, Northeast Battery has top advice for making sure your marine battery stays corrosion-free.
Maintain a Proper Temperature
Marine batteries are durable by nature, but they will get damaged and corroded if they are subjected to temperatures outside of their optimal operating range. A general rule of thumb is that marine batteries should be kept in a mild climate. That might require removing the battery from your boat if it will sit for some time before its next use and storing it in a temperature-controlled environment. Batteries should also be stored in places that are free of high humidity and moisture levels, as both elements can lead to faster rates of corrosion.
Fill With Water
Many marine batteries need to be full of distilled water to function correctly. If the water level isn’t maintained, the battery may have a shortened lifespan. The level of distilled water should be checked periodically and replenished when necessary according to the battery manufacturer’s instructions.
Cleaning
One of the best ways to keep your boat’s marine battery free of corrosion is to make sure it is cleaned frequently and thoroughly. A thorough battery cleaning should involve cleaning the battery terminals, which you can do by disconnecting the terminals and cleaning with a solution made out of water and baking soda. Before you start cleaning the terminals, mix the water and baking soda together until they form a paste-like consistency. The mixture can be easily applied to the terminals using a toothbrush, which prevents corrosion from building up and will also remove any existing corrosion.
If your marine battery already shows signs of corrosion, you can clean it with a wire brush. Doing so will remove any debris, which can cause corrosion, along with the corrosion itself. Be sure to check the cable clamps and battery terminals for corrosion.
Preventing Corrosion
Once you’ve removed any existing corrosion from marine batteries, you’ll want to take steps to prevent corrosion from forming again in the future. This can be easily accomplished by putting a layer of petroleum jelly on the battery terminals prior to reconnecting them.
