Many independent smoke manufacturers in the ship, will be for the independent smoke equipped with a battery, and promoting the battery life of 5-10 years, but home users do not really need so long to replace the battery. Because the service life of the battery is easily affected by external factors, such as temperature, humidity, so that the general battery duration will be shorter than the nominal time. This is why we recommend that users regularly tested on battery power, specific test methods is pressed under the independent smoke test button on the detector, then the independent smoke will send out alarm sound, according to the changes in the size of the alarm sound, easy to determine the residual battery condition.
