When installing a wired GPS tracker, we sometimes find a "remote fuel cut-off" function. However, this is often followed by the text "This function is to be used in conjunction with a relay". So what is a relay? What does it do and how is it wired? This article will give you the answer.
A. The role of automotive relays.
The remote oil/electricity cut-off relay described in this article is a control relay. It is the equivalent of a switch that draws the armature into the circuit by means of a magnetic field, thus driving the contacts to break the normally closed contacts. In this way, it plays the role of changing the control circuit. It is the key to controlling the circuit on and off.

Does GPS have the same life span as cell phones?
What is the reason for the sudden offline display? Next, great-Will GPS trackers takes you to understand these problems.
No matter what kind of product has a life span, you will take that into account when buying appliances such as mobile phones. When buying GPS trackers, I'm sure many of my friends have asked the same question: How long will GPS trackers last? Or how often does the locator need to be replaced?
Perhaps what most consumers are hearing is that regular locators last five to six years. So, does it really take 5-6 years for an electronic product to be continuously updated?
For some wired GPS trackers, as long as they are well maintained and installed, the locator can be used continuously. If you want to use them for 5-6 years, this is no problem. Some of the more advanced manufacturers may try to use better, more durable chips, such as power protection. The GPS trackers will naturally last longer.
As for wireless GPS track...

1, Not what battery can do a super long standby GPS Tracker
For GPS Tracker with long standby times, battery capacity and characteristics determine the length of standby time. As we all know, standby time is directly proportional to battery capacity, and the larger the capacity, the longer the battery life. So battery capacity can be a rough indicator.
However, not all high-capacity batteries are suitable for this kind of positioning. There are many kinds of batteries, and they can also self-discharge during normal use. That is to say, they consume their own power. If the self-discharge of the battery itself is very high, even if the large capacity also holds the concept of super long standby.
One type of battery that...
