The Latest Hot Spots

Does installing a wired GPS locator affect battery life?

At present, car GPS locators are mainly divided into wired and wireless types. Wired GPS locators need to be powered by batteries, so some friends have asked: Will this affect the battery life?We first need to understand that the GPS circuit may appear to be connected to other onboard devices based on different wiring positions, but in reality, it can be simply understood as being powered directly by the battery.By using the fuse of the GPS locator produced by Chongqing Changjian Technology Company, we ensure that the equipment and circuits will not cause bigger problems due to car circuit failures. However, it cannot be ruled out that the shortened battery life may be caused by the following two issues: 1. Improper installationWhen installing a car GPS locator, if the user did not follow the wiring steps for installing the locator or wired it incorrectly at the beginning, it may damage our car battery. If our locator is directly connected to the car's live wire, it will accelerate the battery power loss of the car, causing the battery to feed and burn out our vehicle's battery.2. Improper useIf the user installs a wired GPS locator but does not drive for a long time, the locator will also affect the battery life. If a general user does not drive for more than a week, the locator will directly cause a significant loss of battery power, directly affecting the battery life.Therefore, Chongqing Changjian Technology reminds you that when installing, you need to find a legitimate store for installation and develop good driving habits. This is the only way to put your car in better working condition.
