Lithium-ion batteries are an integral part of modern working life – whether in tools, e-bikes, IT devices or machines. But what many commercial tenants underestimate is that charging these energy storage devices poses risks that can lead to liability in the event of damage.
Anyone who charges batteries in rented premises is obliged to exercise due care and take appropriate protective measures. A fire caused by incorrect storage or improper charging can endanger not only the inventory but also the building itself – and result in high claims for damages.
Why commercial tenants bear special responsibility
Unlike private users, commercial tenants are obliged to run their businesses in such a way that no danger arises for the rented property or third parties. This includes the proper handling of potentially flammable devices – in particular lithium-ion batteries.
Charging generates heat and electrical stress. If batteries are charged on flammable materials such as wooden shelves or in inadequately ventilated rooms, tenants create an avoidable source of danger. If this results in a fire, it may constitute a culpable breach of duty – with far-reaching consequences in terms of liability law.
Typical risk factors when charging lithium-ion batteries
Combustible materials: Charging on wooden, plastic or textile surfaces significantly increases the risk of fire.
Lack of supervision: Unattended charging can lead to the spread of fire in the event of overheating or a short circuit before anyone can intervene.
Multiple charging without a safety concept: Charging multiple devices in parallel in one room increases the risk, especially in combination with older or inferior batteries.
Unsuitable premises: Office spaces, workshops or storage rooms without fire protection insulation are not designed for charging high-performance batteries.
Legal classification: Liability for negligent behaviour
Commercial tenants must always treat the rented property with care and in an appropriate manner. This includes not creating additional fire hazards.
If lithium-ion batteries are charged negligently – for example, on flammable surfaces or without suitable protection – the tenant may be held liable for any damage caused.
Even if there is no explicit charging ban in the tenancy agreement, safety-related duties of care apply by law.
Landlords and insurance companies can claim damages if the fire is due to improper charging or a lack of safety precautions.
Practical recommendations for commercial tenants
In order to avoid liability risks and at the same time protect employees and property, the following measures should be implemented:
- Only charge batteries on fireproof surfaces or in containers
- Clearly demarcate charging areas – separate them from combustible materials or workstations
- Monitor temperature and charge status
- Immediately remove defective or conspicuous batteries
- Carry out charging processes under supervision
- Conduct fire safety training for employees
Professional battery containers and charging rooms with certified fire protection offer maximum safety and also meet the requirements of insurers and occupational safety authorities.
RETRON solutions for safe storage and liability prevention
RETRON offers companies and commercial tenants tried-and-tested safety solutions for handling lithium-ion batteries:
- Fireproof containers and safety containers for controlled loading
- Container systems for defective or used batteries
- Consulting and training on the legally compliant handling of lithium energy storage devices
- Hazardous goods transport solutions for waste disposal and logistics processes
By using RETRON systems, companies not only fulfil their duty of care, but also minimise their liability risk – and ensure greater safety in commercial properties.
Charging lithium-ion batteries in commercial premises is not a routine procedure, but a safety-related activity.
Anyone who acts negligently in this regard risks considerable property damage and personal liability.
RETRON's security solutions and consulting services eliminate sources of danger, minimise fire risks and prevent liability cases – for legally compliant operation and sustainable protection of people, buildings and property.
