Safety reminder regarding lithium-ion batteries aboard boats

Fire services are reporting a growing number of fast-spreading fires caused by damaged or failing lithium-ion batteries. The Boat Safety Scheme (BSS) is also receiving increasing reports of boat-related incidents, from near misses to onboard fires and serious losses, linked to lithium-ion powered devices.

Lithium-ion batteries power a wide range of equipment, from mobile phones, laptops and e-bikes to DIY tools, mobility scooters and portable appliances. On boats, they’re often used for electric propulsion, to power domestic appliances and provide storage for renewable energy sources like solar panels. As these batteries become more common on board, it’s vital to understand and manage the risks.

Simple precautions make a difference

The BSS urges boaters to take the following safety measures:

• Never leave devices unattended while they are charging
• Charge larger batteries off the vessel where possible
• Charge items on stable surfaces, such as worktops, rather than on combustible materials such as bedding or cushions
• Don't overload electrical sockets
• Use only manufacturer-recommended chargers and cables
• Watch for warning signs such as heat, smell or unusual noise coming from the battery
• If you suspect an issue, or the battery is no longer holding charge, ensure you dispose of it properly and safely
• Install smoke detectors, test them regularly and ensure good ventilation onboard

Even small battery-powered devices can ignite fires if they fail, especially in confined spaces.

To help reduce risks, the BSS has created clear advice covering the three main sources of lithium-ion batteries found aboard vessels.
