I could use some help double checking my math. My 05 RSX has a compustar with a pair of dei 530T window modules and 2 amps with RMS power about 650 watts. Now I have left on the headlights 2 or 3 times and as a result the battery was completely depleted. Over the last few weeks it seems like the car will not start after 2-3 days unless I let it run. So I dosconnected the neg cable and took amperage ratings at both unarmed and armed settings.

With the alarm armed and the car sitting I'm pulling .011 with my DMM set to the 2M setting. Now I'm translating that into 110 milliamps. Is that correct or do I need to be edumacated?

Thanks for any help!

Thanks bobk, the battery does indicate it needs to be charged. Am I figuring the milliamps correctly?

I ran a little experiment in the garage here.

I set up a single relay dei, same model I used during the install. I used a 12 volt converter and measured the ampeage being used by the circuit. I set my DMM to the same as I measured the car's battery. I came up with the same thing, a .012 on my DMM, so it must be that by smoking the battery 2 or 3 times I have killed the battery CCA rating.

I have a dei 545T coming to fix the problem where I leave the lights on when exiting the car with the compustar taking over.

Thanks for the help,
