Does Car Alarm Drain Battery. Many auto alarms have to stay in an on mode whenever the car is stationary and turned off. Hooking up one of these types of systems to a car with an old battery will almost assuredly lead to a dead battery.
Hi there - yes a securityalarm system that continues to beephonkwhatever is draining your battery just like a light that is left on. Hooking up one of these types of systems to a car with an old battery will almost assuredly lead to a dead battery. The older a battery gets the less effective it is at holding a charge.
What Drains A New Car Battery.
An alarm is a load and hence drains the battery just as any batterys self-leakage does but that does not necessarily mean a high or unacceptable drain. If you have an aftermarket car alarm then this is one of the first things to check when you have a draining car battery. I always thought that its because I just didnt drive it and forgot to put it on a battery tender when I wasnt driving it months at a time but testing it out over the last couple of weeks - when. Some car battery charges will not charge a completely dead battery.
