Car Alarms

[jim1933]

Hello folks, If we dont use the car for a couple of days it is very hard to start- it is fitted with a Cobra 7928 Alarm and Immobiliser; an auto electrician said you do always get a leakage or loss of charge due to the way an alarm system is functioning could anyone tell us if this is true please? many thanks Jim.

the only power an alarm uses is a flashing led.

Ideally that's true maleborn, but the alarm on my Audi developed a fault whereby it worked fine every time, but periodically drained the Battery completely within a few hours.

An alarm functioning properly shouldn't drain the Battery within a couple of days ! If it is, and you can confirm that it's the alarm, then I'd suggest replacing it. It's not going to fix itself - it'll either stay the same or get worse.
