A loud bang, acrid smell, and smoke – an exploding battery is not just annoying, but can also have dangerous consequences. But who is actually liable when a battery goes off and causes damage?

Causes of Exploding Batteries
To clarify liability in the event of a battery explosion, it’s important to understand the possible causes. A battery can fundamentally explode for various reasons:
- Overcharging: Charging the battery for too long or with too high voltage can lead to overheating and ultimately an explosion.
- Deep Discharge: Excessive discharge can also damage the battery and increase the risk of an explosion.
- Mechanical Damage: Impacts, falls, or cracks in the casing can damage the battery’s internal structure, posing a safety risk.
- Production Defects: In rare cases, manufacturing defects can also be the cause of a battery explosion.
Who is Liable for Damage?
The answer to the question of liability depends on various factors, especially the cause of the explosion and the parties involved:
1. Manufacturer’s Liability
If a production defect is the cause of the explosion, the manufacturer of the battery is generally liable. This applies even if the battery is older. It is important that the injured party can prove the manufacturing defect.
2. Seller’s Liability
If the manufacturer could not detect the production defect (e.g., due to a faulty batch), the seller of the battery may also be held liable.
3. User’s Liability
If the user mishandled the battery and caused the explosion, they are liable for the resulting damage themselves. This could be the case, for example, if they charged the battery improperly or mechanically damaged it.
4. Third-Party Liability
In some cases, a third party may also be liable for the damage. This is the case, for example, if a workshop installed the battery incorrectly, leading to the explosion.

What to Do in Case of Damage?
- Safety First: If possible, move away from the exploded battery and ensure ventilation.
- Document the Damage: Take photos and note down all important details.
- Contact Your Insurance: Depending on your insurance coverage and the cause of the damage, it may cover the costs.
- Consult a Lawyer: Especially for significant damages, it is advisable to seek legal assistance.
Prevention is the Best Protection
While not every battery explosion can be prevented, there are some measures that minimize the risk:
- Buy batteries from reputable manufacturers.
- Follow the instructions in the user manual.
- Use only appropriate chargers.
- Protect the battery from heat, cold, and moisture.
- Immediately replace damaged batteries.
