Battery Safety
There’s no doubt that batteries are an essential part of modern life. From smartphones and laptops to children’s toys, micro-mobility devices, and even cars, lithium batteries power countless devices. While they bring incredible convenience, they also come with potential risks. As a chemical-based energy storage system, any leakage or malfunction can pose a serious hazard.
By understanding how to use lithium batteries safely, recognising early warning signs of failure, and knowing how to respond, you can prevent accidents and protect yourself and your loved ones. Here are PKNERGY’s key recommendations for battery safety.
How to Choose a Lithium Battery?
Choose batteries that have been tested by certified national laboratories or have recognised safety certifications. These batteries undergo rigorous testing for common faults such as leakage, overheating, and combustion to ensure they remain safe under most conditions.
Avoid using old batteries. All lithium batteries rely on chemical reactions to store energy, and over time, by-products form that reduce capacity and efficiency. Old batteries are more prone to overcharging, increasing the risk of failure.
Follow the manufacturer’s recommendations when selecting a replacement battery. Using a battery with a higher voltage or capacity than specified can be dangerous. PKNERGY provides high-quality batteries that meet safety regulations and offers expert guidance on custom battery solutions.
How to Inspect a Lithium Battery?
Checking the external condition of a lithium battery is a quick and effective way to assess its safety. Avoid using any battery that is damaged, swollen, or dented, and handle it carefully.
For batteries that have been stored for a long time, use a multimeter to check the voltage and ensure it meets its rated level:
- Lithium polymer (LiPo) batteries: 3.7V
- Lithium-ion batteries: 3.2V
- LiFePO4 batteries: 3.7V
Stay alert to warning signs such as excessive heat, unusual noises, or discolouration when using lithium batteries.
Why Are Lithium Battery Fires So Dangerous?
When a lithium battery catches fire, it releases an intense amount of heat, smoke, and toxic gases, with the potential for explosion. These fires spread rapidly and pose an immediate threat to human safety.
How to Use Lithium Batteries Safely?
- Do not puncture, crush, or impact batteries, as exposure to air can trigger chemical reactions that may lead to combustion.
- Always follow the manufacturer’s instructions to ensure the battery is being used correctly and matches the required voltage.
- Install batteries properly, ensuring the positive and negative terminals are correctly aligned and that there are no obstructions or signs of rust at the connection points.
- Ensure compatibility—different battery packs may use different battery management systems (BMS), and mismatched components can lead to malfunctions.
- Avoid overcharging—remove the battery from the charger once it is fully charged.
- Monitor temperature—keep batteries within their recommended temperature range and watch out for any signs of overheating.
How to Store Lithium Batteries?
Battery hazards don’t only occur during use—improper storage can also lead to fire risks. Follow these safety tips:
- Keep batteries in a cool, dry place away from direct sunlight.
- Avoid storing large quantities of batteries near flammable materials.
- Regularly inspect stored batteries for signs of leaks or swelling.
- Label batteries with their shelf life to keep track of usage.
Signs of a Failing Lithium Battery
Before a lithium battery becomes dangerous, it may show warning signs such as:
- Leakage
- Punctures
- Swelling
- Unusual heat buildup
- Hissing sounds or smoke while charging
If you notice any of these, stop using the battery immediately and handle it with care.
What to Do If a Lithium Battery Catches Fire?
If a lithium battery starts burning:
- Disconnect it from the power source if it’s plugged in.
- Call emergency services immediately.
- If it’s safe, move the battery to an open area to prevent further fire spread.
- Use a fire extinguisher or water to put out the flames if safe to do so.
- If the fire becomes uncontrollable, evacuate the area immediately.
How to Dispose of Old Lithium Batteries?
Do not throw old batteries, chargers, or battery-powered devices in household waste. Instead, take them to a designated battery recycling centre to ensure safe disposal and environmental protection.
By following these battery safety tips, you can reduce risks and ensure a safer, more reliable experience when using lithium batteries.
