You will have to change the battery in almost every smoke detector at some point. In this article, we have summarized how such a device indicates that a battery change is necessary and what you need to look out for
Changing the battery in a smoke detector – what you should look out for
Smoke detectors are mandatory in most federal states in Germany.
- Smoke detectors approved in Germany must meet certain criteria in accordance with a specific DIN standard. For example, a device must give an audible signal at least 30 days before the battery runs out.
- The smoke detector then beeps every 30 seconds, alerting you to the upcoming battery change. The signal only stops when you have changed the battery
- Some models also provide information via a flashing LED. However, there are also many devices where a flashing LED indicates that the smoke detector is ready for operation. A look at the operating instructions provides information about the LED signal
- Tip: A functioning smoke detector is important for your safety. Therefore, do not rely solely on the device’s signals. Ideally, you should check the smoke alarm once a week to make sure it is working properly. All you need to do is briefly press the test button on the smoke detector. You should then hear a signal tone
- Some smoke detectors do not allow battery replacement. These are so-called 10-year smoke detectors. These devices are now quite inexpensive, but must be disposed of and replaced as soon as the battery performance decreases.
- If you need to replace the battery, follow the manufacturer’s instructions in the operating manual. Incidentally, the standard for smoke detectors also stipulates that the devices cannot be closed without a battery. Therefore, if you remove the old battery, you must also insert a new one
- It is advisable for the consumer world to use the same type of battery again. If you do not want to change the batteries for a long time, you can use high-quality 9-volt lithium batteries. These last up to ten years.
