MES is currently scheduling projects for 2023. Winter is a great time to upgrade to lithium batteries, update those outdated electronics or complete that project you have been putting off.

4 Signs Your Marine Battery Needs Replacing

4 Signs Your Marine Battery Needs Replacing marine electric systems

Should your battery need charging more than usual, or your boat is not running as efficiently as possible, consider getting a new battery.

Lithium technology has improved drastically over the years and is much safer today than before. As a result, there are fewer emergencies involving lithium-ion batteries. However, there are times when things could go wrong when using these batteries. Should your battery need charging more than usual, or your boat is not running as efficiently as possible, consider getting a new battery. Here are some signs your lithium battery needs replacing.

Corrosion

There are often physical signs when a lithium battery is severely declining, or something is wrong with it. Sometimes, you can tell your battery needs to be replaced by looking at it.

Corrosion is fatal for marine batteries, so removing the battery and cleaning it with a baking soda and water solution frequently can prolong its lifespan. Unusable lithium batteries can contain corroded terminals, be warm to the touch, and even swell in size when used. You may even notice a bad smell coming from the battery. If your marine lithium battery exhibits any or all of these signs, it should be replaced.

Reduced Capacity

Anyone familiar with a lithium marine battery 12V knows this battery is famous for its power storage capacity compared to a lead-acid battery. But even lithium batteries don’t last forever, and reduced power storage capacity is typically the first sign of performance decline. If you notice you aren’t getting the same kind of longevity and power storage in your battery as you used to, it may be because your battery is on the decline.

Higher Self-Discharge Rate

As with its power storage, lithium marine batteries are known for their incredibly low self-discharge rate—giving boaters more battery power for longer. But, like with the storage capacity, a lithium battery can’t retain its fantastic self-discharge rate forever.

After some time, a lithium battery may exhibit a higher discharge rate, slowly at first, but it can increase to an unusable level. If your lithium battery won’t hold a charge anymore, and the charger seems to be functioning properly, that’s a sure sign to start looking for a new battery.

Overheating

Overheating is an obvious sign of a malfunctioning battery. Be sure to check the battery specs and identify the normal operating temperature. If the temperature is too high, it should be considered a cause for alarm. Overheating can damage your device and even lead to an electrical fire.
