Let’s look at the crucial question — can lithium batteries get wet?

It’s common knowledge that water and electricity don’t mix, but what does that mean for your marine batteries? Like most electronics, lithium batteries should NEVER be submerged in water. While most consumers would never choose this scenario, many are curious about how much their batteries can resist water. Most top-of-the-line lithium batteries can endure moist conditions. So, let’s look at the crucial question — can lithium batteries get wet?

What to Know About Lithium Batteries

Lithium batteries work similarly to lead-acid batteries. They both have a cathode, an anode, and an electrolyte solution. When energy is drawn from lithium batteries, the ions move through the electrolyte solution to the cathode, giving up their electrons to produce electricity. 

However, unlike lead-acid batteries, lithium batteries are entirely sealed. This allows the electrolyte solution to remain balanced throughout the battery’s life without needing maintenance or regular inspections. The sealed design keeps internal elements safely inside the battery and prevents anything from getting in, protecting the batteries and making them inherently safer than lead-acid ones.

Can Lithium Batteries Get Wet?

The short answer is sometimes. This will depend on the quality of the battery and the manufacturer’s design. However, prolonged exposure to moisture may cause water to penetrate the battery and cause irreversible damage.

When considering lithium-ion batteries, it’s essential to learn the manufacturer’s specifications regarding their water exposure. As previously noted, most lithium batteries are sealed cells, meaning they have some inherent protection from water. However, not all seals are created equal. Depending on the design, the amount and duration of water exposure can drastically impact battery health. Generally, most lithium batteries can withstand some rain or accidental splashing. Still, depending on the recommendations of your battery’s manufacturer, taking further precautions against water exposure may be beneficial.

Although different types of lithium batteries offer varying degrees of water resistance, they should never be submerged in water. Submerging any battery in water will significantly damage it. Water infiltrating lithium batteries can reduce performance or render the battery inoperable. Therefore, although it’s always important to protect your batteries from excessive water exposure

Protecting Lithium Batteries from Water Damage

While some water won’t harm your batteries, taking basic precautions to keep them dry will minimize the risk of water damage. If possible, install your battery in a covered location away from water. Garages, storage bays, and other enclosed spaces are great options for battery placement. 

It may sound simple, but being aware of excess water exposure when using your vessel during heavy rain or other extreme precipitation can go a long way in keeping your batteries safe.
