Hello everyone, I have been trying to isolate a current draw that surface only when my alarm is armed. With my digital Ammeter i would get .135 amps when armed and .25~.3 amps when disarmed.

I go to school elsewhere and i am not really able to drive the car everyday. So sometimes it is left for 2 weeks.

I read froom alot of places that 30-40mA is recommended.

I am wondering whats a general current draw people have with these components installed and what recommendations in regards to my case when the car can be off duty for 2+ weeks

components installed:

TurboTimer
Boost controller (may or may not have parasitic drain)
Greddy Fuel controller
Aftermarket stereo (nothing big, and only memory should be from the radio)

those above make up the .025~.035A draw

alarm system - 2 way long range (tried unplugging some sensors, LED, etc without much change)

the alarm when armed draws .1A

Thank You
Jonathan

 

IIRC, a typical battery has 50 amp hours of juice in it, give or take. If I don't remember correctly, then it's still gotta be at least 30 Ah, even for a small battery.

So with .3A on a 40Ah battery you'll last about 130 hours or 5 days.

You could always disconnect your battery if you plan on going somewhere for a while. Your alarm won't work and you'll have to set the time on your clock later, but besides that you'd be fine. You could also leave the battery connected and hope for the best. If it dies, get a friend with jumper cables to recharge it. Not good for your battery to do often, but doing it on ocassion isn't so bad.

 

You could also just leave the car connected to a trickle charger, then you wouldn't have to disconnect the battery and the car would be ready to go.

 

i don't have access to a garage (sad i know) and i use the costco generic batteries, it seemed to last a week before it dies,

but even after a week say i can start it with enough juice, is would the stock charging system be adequate?

also my brother-in-law have those things that cut your battery when the voltage drops below a certain point, and when the ignition is sensed it will engage the battery again. is that another good option?

something similar to this

Solution=Really long extension cord.
