If your battery needs charging more than usual or your boat is not running efficiently, you may need a new battery.
Marine lithium batteries are known for their outstanding longevity compared to standard lead-acid batteries. But even lithium batteries don’t last forever; sooner or later, they display signs of decline. However, the issue with a bad marine battery is that if it goes wrong, you could find yourself stranded on the water. If your battery needs charging more than usual or your boat is not running as efficiently as it should, you may need to consider getting a new battery. Here are a few signs that you need a new marine battery.
The Battery Charges Slowly
Have you noticed your battery is charging slower than it once did? This may be cause for concern. A slow-charging battery is generally regarded as a battery near the end of its lifespan. That said, other problems can lead to this. For instance, the charger itself could be damaged. Or, you might not be maintaining your battery properly. It is best to have a professional marine electrician inspect your battery. They’ll decide whether it’s worth repairing or whether it’s time to replace the battery entirely.
Reduced Power Storage Capacity
Deficiencies in the marine battery’s performance can also signal a decline. A lithium marine battery 12V is famous for its power storage capability compared to traditional batteries. But this remarkable performance doesn’t last forever, and when it starts declining, the power storage capacity is typically the first indication. If you aren’t getting the same kind of longevity and power storage that you used to, it may be because your battery is on its last legs.
Signs of Corrosion
There are usually physical signs when a lithium marine battery is declining. You may be able to tell your battery needs to be replaced simply by looking at it. Corrosion is fatal for marine batteries, so cleaning the battery with baking soda and water can prolong your battery’s lifespan.
Unusable lithium batteries can have corroded terminals, be hot to the touch, and even expand in size when used. Upon inspection, some owners notice a rotten smell coming from their boat and realize it’s coming from the battery. If your marine battery shows any or all of these signs, it must be replaced.
The Battery Casing is Cracked
Battery casings crack for a variety of reasons. Sometimes, it’s due to direct physical trauma; other times, they crack due to ultra-tight terminals or expanding chemicals within the battery itself. Regardless, this issue will generally trigger a replacement. In the most severe cases, a cracked battery is also at risk of overheating and exploding.
