Can a car alarm light wear down the battery?
light on the dash will be blinking for six weeks and could wear down the battery—or is the battery drain from an LED so weak that I have nothing to worry about. The LED is nothing but the alarm itself plus other parasitic loads may indeed drain the battery…
Why does my car alarm keep going off at night?

How can I tell how long a light will run off a battery?
These types of batteries will run down much faster than a Deep Cycle Battery and your light will not burn as bright or as long as it should. A Simple Formula to find out how long a light will run off of your particular battery is to take the batteries “amp-hour rating” and divide it by the average load in amps.
