Can Lithium Batteries Get Wet? How to Avoid?

Lithium batteries, including those designed for marine applications, have become a cornerstone of modern life. From powering trolling motors to providing reliable energy for RVs and boats, their versatility is unmatched. However, a common concern arises: Can lithium batteries get wet? This article explores what happens if lithium batteries encounter water, how to avoid getting batteries wet, and steps to ensure their safety and longevity.

Can Lithium Batteries Get Wet?

It depends on the battery manufacturer’s design. Some smaller manufacturers may produce lithium batteries without waterproof capabilities, while advanced manufactures and brands like Redodo lithium batteries make them highly resistant to water damage. Key considerations include:

IP Ratings: The IP rating (Ingress Protection rating) in batteries indicate their level of protection against dust and water ingress. High-quality lithium batteries feature IP65 ratings. This means they are completely dust-tight and can withstand water jets from any direction, but is not suitable for immersion in water.

Redodo lithium batteries are fully sealed and IP65/IP67 rated, making them water resistant and splash-proof, making them ideal for marine use. However, it’s necessary that avoiding prolonged exposure to a high-moisture environment or immerse in water for more than 30 minutes, which may cause water to penetrate the battery and cause irreversible damage.

Freshwater vs. Saltwater: Freshwater has a lower conductivity level compared to saltwater, while saltwater poses a greater threat due to its conductivity and corrosive nature. Some advanced marine batteries from Redodo are built with enhanced protection against moisture and salt spray to combat such conditions.

What Happens If Lithium Batteries Get Wet?

When lithium batteries get wet, the outcome largely depends on the type of battery and the extent of water exposure. For lithium batteries, water ingress can lead to several issues:

• Short-Circuiting: Water can create a conductive bridge between the positive and negative terminals, leading to a short circuit. This could damage the battery permanently and even pose a fire risk.
• Corrosion: Water, especially saltwater, can cause corrosion of the battery’s internal and external components, reducing its efficiency and lifespan.
• Battery Damage: Moisture can interfere with the inside of the battery and damage the cells, ultimately leading to the battery failure. 

How to Avoid Getting Batteries Wet?

Protecting your lithium batteries from water exposure is crucial. Here’s protective measures to avoid batteries getting wet:

1. Choose Water-Resistant Batteries

Select batteries with an IP65 or higher rating. Redodo’s lithium batteries are built with IP65 ratings, ensuring protection against water and dust. The marine cranking batteries are designed for a higher IP67-rated casings, making them ideal for boating and other water-based activities.

2. Proper Installation

Even with water-resistant designs, installing batteries in dry, well-ventilated compartments is essential to minimize direct exposure to water.

3. Use Battery Boxes

If possible, consider using a waterproof battery box or enclosures for added protection in marine environments. These enclosures provide an extra layer of protection against battery getting wet.

4. Regular Maintenance

Inspect the battery and its connections regularly for signs of corrosion or water damage. Clean and dry any moisture-prone areas to prevent long-term issues.

Steps to Take If Your Lithium Battery Gets Wet

If your lithium battery gets wet or in water, follow these steps to handle:

1. Disconnect Safely: Turn off and disconnect the battery from all devices.
2. Dry Thoroughly: Wipe with a dry cloth and air-dry in a warm, ventilated area. Avoid heat sources like hairdryers.
3. Inspect for Damage: Check the battery for corrosion, swelling, or leaks.
4. Dispose Responsibly: If damaged, contact the battery manufacture for safe disposal. 

Upgrade Redodo Smart Lithium Batteries for Marine Use

Redodo’s LiFePO4 batteries are engineered for reliability and safety in marine and outdoor environments. Here’s why they excel:

• High IP Ratings: The IP65/IP67 rated casings resist water and dust, ensuring the batteries are resilient against moisture ingress. It makes them ideal for marine environments where exposure to water is common.
• Salt-Spray Resistance: With salt-spray resistance, Redodo batteries are more durable and able to withstand the corrosive effects of saltwater, ensuring reliable performance even in harsh marine conditions.
• Low-Temperature Protection: The advanced low-temperature cutoff protection feature enhances safety during charging by preventing battery damage that can occur in cold weather conditions.
• Long Lifespan: With 4,000+ cycles at 100% DOD and 15,000+ cycle at 60% DOD, Redodo batteries offer up to 10-year lifespan for long-term cost savings, while lead-acid AGM batteries last only 2 to 3 years.
• Smart Monitoring: Some of Redodo lithium batteries come with advanced Bluetooth-enabled systems, allowing for real-time monitoring the battery health status. Additionally, the Bluetooth can support remote power management.
