Which is permissible drain on a car battery?
Since besides the permissible car battery drain, current consumers such as alarm system and immobilizer (20-25 mA), audio system (3 mA), central lock unit and ECU controller (5 mA) can consume current even at solid state, static current is much higher.
Why does the Green immobilizer light not go off?
My 04 MDX sat for maybe 2 months and the battery drained. When connected to a jump starter it cranks but won’t start. I notice that the green immobilizer key light on the dash blinks and doesn’t go off (both during cranking and the II position).
What causes a car battery to drain while standing?
Excessive drain current in a car leads to the battery discharge when standing. The causes and check of the drain should be considered separately.
How much can a car battery drain per day?
Self-discharge of the battery in an open circuit is allowed by no more than 1% per day. But given that it is constantly connected to the vehicle network, this value can reach up to 4 percent. Thus, the permissible battery drain is equal to the capacity multiplied by a factor of 0.4.
How to get rid of negative battery drain?
Remove the negative battery cable from the negative battery terminal. Find the negative cable, which will be marked with a minus sign (-) and may have a black cover over it. Remove the cover, if applicable, and use a wrench to unbolt the negative cable from the terminal.
How to find the cause of parasitic battery drain?
Luckily, you can usually find the cause of a parasitic draw yourself. Start by connecting a digital multimeter to the negative battery terminal of your vehicle. Then, remove the fuses one at a time while watching for changes in the multimeter’s reading.

Why does my immobilizer light keep flashing?
😉 The fact that the immobilizer key light flashes continuously does suggest that the system DOES see the key, but that it’s not a recognized key, so either the key transponder died, or the immobilizer system lost its memory with the battery out (most likely).
