With Christmas just around the corner, many of us are facing that familiar December dilemma: “What on earth am I buying everyone this year?” And while socks will always have their place, the reality is that more and more gifts these days are electronic. From the latest smartphone or gaming headset to e-bikes, e-scooters, kids’ toys and tools – our festive season is becoming increasingly powered by lithium-ion batteries.
And for good reason. Lithium-ion batteries have transformed modern technology. They’re lightweight, hold their charge for longer, recharge quickly, and can go through thousands of charge cycles without showing much wear. But as brilliant as they are, they come with a serious safety consideration we can’t afford to ignore.
The Hidden Risk: What Is Thermal Runaway?
Most people don’t realise that lithium-ion batteries can become dangerous if they’re damaged, poorly made, overheated, or charged incorrectly. When things go wrong, they can enter a state called thermal runaway – a chain reaction where the battery overheats faster than it can cool down.
This can cause the battery to:
- Vent toxic and highly flammable gases
- Catch fire
- Explode
- Spread heat to nearby batteries and cause further failure
This isn’t a theoretical threat either. Thermal runaway is incredibly difficult to extinguish, and the fumes released are hazardous.
Why the Rise in Battery-Related Fires?
Although still uncommon, lithium-ion battery fires in homes are increasing at a worrying rate. Combine this with the bare minimum fire alarm standards in many Irish homes – just one alarm per storey – and it’s easy to see how quickly danger can escalate.
If our homes and lifestyles have evolved, our fire protection standards should too.
According to WEEE Ireland, Ireland’s battery‑recycling results are still far from perfect. Their data shows that only about 51% of batteries sold in Ireland were returned for recycling in 2024 – meaning more than half never make it back into the circular‑economy system.
WEEE Ireland is now strongly recommending F‑500 fire extinguishers for battery-related fires. This came up repeatedly in their recent seminars and guidance. Unlike regular extinguishers, F‑500 is specifically designed to safely suppress lithium‑ion battery fires, reducing heat and toxic gas release, and preventing fire spread.
How to Stay Safe: Practical Battery Safety Tips
Lithium-ion batteries aren’t going anywhere – and neither are our gadgets. The good news is that with the right habits, they’re safe to use.
Here are simple steps that make a big difference:
Charging and everyday use
- Use manufacturer-approved chargers
Cheap or counterfeit chargers often lack essential safety features. - Charge devices on a hard, non-flammable surface
No sofas, beds, or piles of clothes. - Avoid overcharging
Modern devices help prevent this – but it’s still good practice to unplug once full. - Watch the temperature
Batteries dislike extreme heat and cold. Keep them within a safe, moderate range. - Replace anything damaged
Frayed cables or swollen batteries are a fire hazard. Stop using them immediately. - Unplug chargers when not in use
It prevents faults and reduces fire risk. - Use surge protectors
Especially for high-value electronics.
For e-bikes and e-scooters
- Never charge them in escape routes such as hallways or near front doors
If a fire starts, you could block your only way out.
For the whole household
- Teach family members to charge safely
Especially children and teens. - Follow manufacturer instructions
Every device has its own do’s and don’ts.
Lithium Batteries at Work: An Employer’s Responsibility
It’s not only households feeling the pressure. Workplaces now rely heavily on lithium-powered tools, machinery, and equipment – and employers have a legal duty to assess related risks and put proper measures in place.
This includes safe storage, regular inspections, proper charging stations, and ensuring products meet the standards required for commercial use.
Safe Handling of Batteries: When handling waste batteries, use personal protective equipment (PPE) such as gloves to protect your hands. Batteries may leak acid or electrolyte that is corrosive.
Practice proper manual handling technique when carrying larger batteries which may
be heavy or awkward to lift. Specifically avoid short-circuiting batteries by connecting
battery terminals. Never pierce, crush, throw or drop batteries from heights due to the
associated fire risk.
Safe Storage of Batteries: Any type / chemistry of battery, if still holding a charge, can short circuit and result in a fire. Batteries should be stored in a cool, dry weatherproof and supervised location
away from direct sunlight, heat or any other combustible material. Batteries should
always be stored out of reach of children or animals. Large quantities of batteries
should not be stored for extended periods of time.
Batteries should only be stored in approved boxes and containers supplied by KMK. Where you have
lithium-type batteries stored together, KMK advise that the terminals of these batteries be taped to
avoid short circuit and/or fire. Batteries should not be wrapped in conductive materials like aluminium
foil or stored in metallic containers. Never mix other wastes with waste batteries
Emergencies: Emergencies relating to waste batteries are extremely rare and are mostly associated with lithium-type batteries. Damaged batteries are identifiable where they expand in volume, produce a hissing sound, visibly smoke or get excessively hot. In the unlikely event that you become concerned about the condition of a waste battery you should: 1. Call Emergency Services immediately and seek advice. 2. Notify your designated workplace Health and Safety Officer immediately. 3. Contact WEEE Ireland or KMK with feedback following the event.
