car amps

I have an amp in a car. I thight it may be sucking too much current in off mode.
its pulling 40 ma. in off. Anyone know typical current draws of typical amps?
My car often sits for long periods of time. Even months. Thats 1 AHr in 24 hours. Too much.

By being in off mode, do you mean that no voltage is going to the remote
turn on? Or when the car is off?

My first knee-jerk response is...if you can put together this much
information on the sitation itself...why do you need help with the
solution?

Try hooking it up to a charger. Much higher current than a paltry 40
mA.

You are not taking care of your car properly. Car batteries are designed to

basis. Otherwise you need to put the car on a trickle charger.

40mA is in reality virtually nothing. Most modern car computers draw 50ma
give or take when the car is off, add the car stereo/clock and easily you
have 100ma.

You are looking at a car battery with more than 1000 AMPS available current.
Granted 500 amps or so is required to start the car. The cars battery will
slowly have as much or more internal leakage current than total standby
draw of what is in your car. 40mA is well within tolerance for a device.

If it really sits for months at a time, you have bigger concerns than the
battery, like dry seals, sitting dirty oil, dry rot in the tires, etc.
Suggest you check into the proper preparations for keeping a car in storage
or non-driven condition, Or get out to the car, start it up once a week, and
drive it at least 30 minutes continously to get everything al the way hot,
charged up, and lubricated.
After owning my Datsun 280Z for 26 years, I think I know what to do, how to do
it, and when I want or need to do it.

I had a Ford once that had a leaky brake light switch that of only 100 ma.
could discharge a less than perfect battery fairly fast. After I fixed the switch, it worked fine.

Does anyone know how much a typical power amp draws, because
I need to know if I need to order a new one.

Thank you

I measured a small older Alpine amp that was here
and it reads no current draw at all with the remote
lead open.
This is what I would expect.
