Why battery safety is so important
Lithium-ion batteries have become indispensable - whether in smartphones, tools, laptops, e-bikes or even electric cars. Their high energy density and compact design make them powerful, but also fragile. Incorrect handling, improper storage or hidden damage can lead to risks that should not be underestimated.
Hazards can be significantly reduced with a clear battery safety checklist.
1. visual inspection before each use
Before using or charging a battery, you should carry out a visual inspection:
- Are there any visible cracks, dents or swelling on the housing?
- Does the battery smell chemical or unusual?
- Does it generate heat even though it is not in use?
- Do the contacts show corrosion or discoloration?
Important: Do not continue to use batteries that are conspicuous or damaged. Store them in a fireproof bag and have them disposed of properly.
2. observe safe charging
Charging is a critical moment. Therefore, follow these rules:
- Only use the original charger.
- Load on a non-flammable surface.
- Do not leave the battery unattended - especially not overnight.
- Ensure good ventilation.
- Keep the surrounding area free of flammable materials.
Additional safety is provided by the use of fire blanketswhich contain flames and smoke in an emergency.
3. store correctly when the battery is not in use
Batteries should be stored correctly when not in use for long periods:
- Store partially charged (30-60%) to extend the service life.
- Temperatures between 10 and 25 °C are ideal.
- No direct sunlight or moisture.
- Store in fire-retardant battery-safe shelves or bags.
This ensures that there is no unnecessary risk, even in idle mode.
4. recognize warning signs during operation
Malfunctions may occur during use:
- Sudden drop in performance or rapid discharge.
- Unexpected heat development at low load.
- Charging problems or frequent interruptions.
- Irregular switch-off of the appliance.
If you ignore such signs, you run the risk of dangerous battery damage.
5. replace defective and old batteries
A lithium-ion battery is not a product for life. Performance decreases after 300-500 charging cycles. Replace batteries in good time if:
- the range decreases significantly,
- the battery becomes excessively warm,
- or visible damage is recognizable.
Old or defective batteries should not be disposed of with household waste, but should be taken to a municipal collection point or a specialist retailer.
6. fire protection and emergency preparedness
Despite all caution, a battery fire can occur. It therefore makes sense to be prepared:
- Hold a fire blanket handy.
- Use suitable fire extinguishers (e.g. CO₂ or extinguishing granules).
- Do not use water for battery fires.
- If smoke or flames develop, call the fire department immediately.
Note: It is particularly important in workshops and companies to train employees in handling batteries and fire protection measures.
7. private vs. commercial use
While only a few batteries are usually used in private households, dozens or hundreds can quickly add up in businesses. Additional safety measures are essential here:
- Private household: fire protection bags and small fire blankets.
- Workshops: Battery-safe shelves and temperature monitoring.
- Companies with e-mobility: quarantine areas and special fire blankets for vehicles.
Conclusion: caution protects against damage
Lithium-ion batteries are safe when handled correctly. However, regular testing, correct charging behavior and proper storage make all the difference. With this battery safety checklist, you can ensure that risks are identified and minimized.
