Marine Battery and Boat Battery FAQs

At Battery Giant, we want our customers to be happy with their marine battery purchase. We achieve this by providing our customers with all the information they need regarding marine batteries and marine batteries. Below are basic marine battery and boat battery FAQs to help answer any of your general questions.

Q: How does a marine battery or boat battery work?
A: A marine battery or boat battery works similar to other common batteries. Marine batteries store energy in a chemical form that can be released on demand as electricity. Each marine battery or boat battery cell consists of positive plates, negative plates and an electrolyte solution. Marine batteries produce electricity because of the chemical reaction between these elements.

Q: What should I consider when purchasing a replacement marine battery or replacement boat battery?
A: There are three important factors to consider when buying replacement marine batteries. While shopping for a replacement marine battery, it is critical to consider size, power and warranty. Although it is recommended to consult the watercraft manufacturer's recommendations in attaining the correct replacement marine battery, below are some general factors to consider while selecting a replacement marine battery.

Make sure the replacement boat battery or replacement marine battery will fit and work correctly. Check the specifications of the existing marine battery, as well as the physical dimensions of marine battery. The marine battery specs will provide the information you need to target applicable boat batteries. Two critical specs you need when shopping for a replacement boat battery or replacement marine battery is voltage (or power) and size dimensions. This will allow you match the correct marine battery with that of your boat. Next, you need to consider the boat battery or marine battery warranty period. We recommend choosing replacement marine batteries with a warranty period that best fits your needs.

Q: What causes replacement marine batteries for boats to fail?
A: There are several factors that contribute to the failure of replacement marine batteries for boats. Excessive heat causes corrosion, which can dry out the replacement marine battery cell. Extreme cold weather can sometimes put a heavier drain on replacement boat batteries. This is sometimes a common contributor to replacement marine battery and boat battery failure.

Also, if a marine battery is not securely held down, vibrations can shed the active material from the marine battery plate grids. This will cause depreciation in a typical boat battery application. Overcharging a marine battery may cause overheating. Although typically a prolonged process, overcharging boat batteries can eventually cause a boat battery or a marine battery to depreciate. Other possible factors that can cause a marine battery or boat battery to fail include corroded terminals, sulfation due to inactivity, or electrical shorts in the marine battery itself. These are just some of the common causes of marine battery failure. Marine batteries can vary in composition, which can influence how a replacement marine battery depreciates.

Q: What is the best way to store a replacement marine battery or replacement boat battery during the off season?
A: Before storing a replacement marine battery or replacement boat battery, make sure it is fully charged. Remember that fully charged marine batteries will usually not freeze, but a discharged replacement marine battery or boat battery can freeze. Test your replacement marine battery and charge it if necessary. It also might be wise to purchase a marine battery maintainer. After a full charge and test, now you are ready for replacement marine battery storage. It is important to store a replacement marine battery in a cool, dry and well ventilated area out of the reach of children or pets. Check the charge level of a replacement marine battery every 30-45 days. A trickle charge using a marine battery maintainer or low amperage charge overnight might be necessary for some replacement boat batteries depending on their age and composition. Also a good replacement boat battery storage precaution is to check the fluid level inside the boat battery. If the fluid level is low inside the replacement marine battery or replacement boat battery, add distilled water.

Q: How do you properly charge a marine battery?
A: Proper charging of a marine battery or boat battery is important. While the marine battery charger or marine battery maintainer is still unplugged, connect the leads to the proper (+)(-) terminals. Wiggle the marine battery connectors to ensure a good connection. Adjust the settings on the boat battery charger for correct voltage and amperage. Now you can plug in the boat battery charger and turn it on. While charging marine batteries in a well-ventilated area, periodically check on the marine battery for any obvious signs of charging malfunctions. Make sure that while charging marine batteries or boat batteries that there are no signs of overheating. If the replacement marine battery is too hot to touch or if the replacement marine battery is gassing profusely, turn the boat battery charger off immediately. Once the marine battery is fully charged, turn the boat battery charger off, unplug it from the wall and unhook the boat battery charging cables. Always use caution when charging marine batteries and boat batteries.
