Corroded Or Rusted Battery Terminals
A low battery level is one thing that sets your car alarm off, while corroded battery terminals are another. In this second scenario, the battery is not necessarily running low. But because of the rust forming on the terminals, the battery cannot give off enough power to different car parts. Your vehicles alarm system then interprets this as a low-battery condition and consequently sets off the alarm to give you a warning.
Apart from moisture and salt, improperly charging your car battery can lead to rusting or corrosion. When a battery is undercharged, corrosion forms on the negative battery terminal. Conversely, an overcharged battery will have rust visible on the positive battery terminal. You can clean corroded battery posts and terminals using a commercial-grade battery cleaning agent and a wire brush, as long as there is only minor corrosion. But if both battery terminals are severely rusted , I suggest replacing the entire battery.

The security system sometimes has a backup power source in case a potential thief cuts the battery cables to try to make a quiet getaway.
Basic alarms sense a big drop in voltage, like if a door is opened, an attached trailer with an electronic connection to the car is detached, etc. The computer can then react.

Different cars have different shock and movement sensor types. Older cars, for instance, normally have only two types of sensors a door and a shock sensor. Whereas more recent vehicles would have more. Older sensor types would have fixed settings, while newer ones may be adjustable.

Door sensors, shock sensors, microphone sensors, proximity sensors, glass-break sensors, and tilt sensors even if only one of these gets triggered, your car alarm will surely go off.
