Keeping a marine battery healthy requires a lot of knowledge, maintenance and care. Here are some of the best practices that will help you make sure that your battery stays healthy and strong.
Cleaning away corrosion
Cleaning away corrosion is one of the simplest ways to keep your marine batteries in good condition. Usually, corrosion is the result of a chemical reaction between the battery acid and metal terminals. Keeping your batteries and equipment in good condition helps avoid inoperabilities.
Battery corrosion can damage electronics and other equipment. It is a common problem, but it’s not hard to prevent. A simple terminal protector will help protect your battery against corrosion.
Keeping your batteries clean will also allow you to charge your batteries properly. Some of the best ways to do this include storing them in a cool, dry environment, and removing corrosion on a regular basis.
The easiest way to remove Corrosion is by using plain soap and water. However, you can also use a more specialized cleaner.
Preventing water from entering the battery
If you own a boat, you know that the battery is a crucial part of the operation. Batteries that are improperly maintained or filled can lead to serious problems, like corrosion and overflow. To make sure your battery is in good working condition, here are some tips for you.
First, you’ll need to fill the battery to the manufacturer’s recommended level. It’s best to use distilled water. You can get it at most stores.
Next, check the electrolyte level. The normal solution should be one cm above the lead plates. Diluted chemicals can cause skin irritation and even burns. Besides, you don’t want the electrolyte in contact with your eyes.
If your batteries are older, they should never be filled to their maximum capacity. This could aggravate the buildup of lead sulfate deposits and shorten the life of your batteries.
Performing routine voltage and specific gravity checks
The battery is the heart of your DC electrical system. In order to keep it in tip top condition, you should perform routine voltage and specific gravity checks. It’s also a good idea to get a load tester.
First, you’ll need a good hydrometer. These little jewels can be found for a few bucks at most auto parts stores. They’re a great way to test your battery’s water level without a drop of a drop. You’ll also want to test the electrolyte’s alkalinity by soaking a small sample in a glass of vinegar.
Aside from water level checks, you’ll want to perform other routine maintenance like checking your crankcase oil and making sure your battery jack is in tip top shape. Performing a quick check every few days will ensure your boat’s DC electrical system remains in tiptop shape.
Proper watering
It is important to properly water your boat battery to keep it healthy. The best way to go about it is to follow the manufacturer’s directions. For instance, you might want to use distilled water, rather than tap water. If you’re able to, you might even consider buying a watering system that fills the batteries for you.
Batteries are a sizable investment. They can last for years with proper care and maintenance. However, they are not meant to withstand extreme temperature swings. That means you may need to remove them from the boat when it’s cold outside.
You should also take the time to learn more about your marine battery. Some of the most powerful batteries are made of lead, so you’ll need to follow some safety guidelines when you’re working with them. Make sure you wear protective gear and use the appropriate safety tools.
Li-ion batteries
Lithium-ion batteries are ideal for use in marine applications. They provide consistent voltage for the majority of the discharge cycle, and are lighter than lead-acid batteries.
The lithium-ion battery market is expected to continue expanding at a significant rate during the forecast period. Growth will come from a variety of sources, including investment in ship electrification and the restructuring of marine industry firms.
For many years, lead-acid batteries have been the dominant marine battery type. But new manufacturing breakthroughs have led to longer-lasting, more energy-efficient batteries. A new research effort is focusing on the health of marine batteries. Better data will allow for better understanding of how the batteries are performing, and will help predict battery replacement needs. This information will be essential to build confidence in hybrid systems.
