Does a motorcycle alarm consume a lot of power?
1 Answers
Motorcycle alarms generally consume very little current, typically around 20mA, which usually has no significant impact on the battery. However, if it is a low-quality alarm, the current consumption will be higher. Low power consumption scenario: When selecting an alarm, check the manual for the static current value, which indicates the power consumption when the alarm is not activated. If you want to turn it on only when in use and off otherwise, you can cut the positive power wire of the alarm (the one connected to the battery's positive terminal) and connect it in series with a switch for control. High power consumption scenario: If the alarm consumes 200mA and the motorcycle is not ridden for three days, the power consumption would be 24x3x0.2=14.4A.h. For a 7A.h battery, this would definitely lead to battery drain.
