What is an acceptable battery draw?

In fact, we suggest a 25-milliamp draw is acceptable and anything that exceeds 100-milliamps indicates an electrical issue that needs to be addressed.

How many amps does a dead battery draw?

Most vehicles draw some battery current when the key is off, thanks to the clock and the internal memory of engine computers, body-control modules, and radio presets. Altogether, they draw a very small amount of current. Fifty milliamps would be a safe upper limit for this, though many vehicles will draw less.
