What is the typical parasitic load on a car battery?
A normal amount of parasitic draw for newer cars is between 50-milliamp to 85-milliamp current draw. A normal amount of parasitic draw for older cars is a reading less than 50-milliamp. Anything past these amounts indicates an electrical issue and should be addressed by a mechanic.
How long does it take for Honda Accord battery to drain?
It drains the battery in about 3-4 days. So if a park the car on Friday and don’t drive it again until Monday, it’s really slow to crank. If I disconnect the battery for the same time frame all is fine. Oh – this is my third battery – so it’s not the battery. iPod adaptor completely removed > NO CHANGE.
What’s the current draw on a Honda Accord back up?
1) Hooked up the meter in series to the negative battery cable. Meter reads 7.18 (20mA/10A scale) current draw. 2) UNDERHOOD – If I pull the: #15 40amp fuse labeled “ Back up, ACC” > the current draw drops to 0.48mA (seems acceptable from what I’ve read). a. I have pulled all the other fuses and relays underhood and no change.
Why does my Honda Accord lock up when I turn the key?
But after the car got cold it would lock up and not crank. When i would turn the key all the lights would dim, because of the massive current draw to a bad starter. The current draw to the fuse was actually the computer which takes a while to shut down after you take the key out.
Is the Honda Accord battery subject to parasitic drains?

What to do if Honda Accord battery is dead?
The VSA modulator will continue to draw 350mA of power after the vehicle is shut off. More than enough to drain the battery after a day or two. Honda recommends technicians install a software update to the VSA modulator-control unit and perform a VSA sensor neutral position memorization procedure.
Why is my Honda Accord battery not charging?
Both service bulletins describe an issue in the powertrain control module (PCM) where the proper charge mode for the battery is not selected when the vehicle is turned off. The system’s computers need a software update with a functional battery present. When the engine is running, the alternator charges the battery.
Why does my Honda CRV have a dead battery?
However, those fixes aren’t always effective and have been limited to the 2012 and 2017 model years. The batteries are contending with a parasitic drain, which happens when an electrical component continues to draw power from the battery even after the vehicle is turned off.
