G35 coupe auto battery drain ?
Hi everyone, need some help guys please ,
skyline 350gt auto, i live in the uk and owned the car for 10 years, it is totally standard
if i leave the car for like 3 days the battery is flat
if I jump start it with leads it drives and charges, then after a few miles it has charge and starts again
so over the years I’ve just kept it charged and maintained and driven and just lived with it
i upgraded the small Nissan battery to a normal size one
the only aftermarket kit is an immobiliser and a tracker
after another breakdown yesterday because I left lights on for like 10 mins it’s finally time to get it fixed
ive always thought it was the tracker that is draining the battery, car is perfect, no faults or electrical gremlins, no extra equipment like stereos etc
so before I call someone out I thought I’d ask you guys if there is anything I should look at first
had battery checked yesterday, it’s gone, fitted a new one today, alternator is fine
any help is greatly appreciated
cheers

What was the CCA rating of your original battery and did you upgrade the replacement battery with a higher CCA rating?
By using a lead acid battery with vent caps as opposed to a sealed battery it is quite easy to determine the charge level in each battery cell by using a battery hydrometer.
If you are still worried about current draw use a multi-meter to measure current draw by putting the meter in series with your battery cable.
Your problem most likely was a weak or dead cell in your old battery and consider yourself lucky if it lasted ten years. I never keep a battery longer than four or five years and monitor the cells carefully after four years as we have very cold winter temperatures here in New Jersey.

Many folks have reported that the OEM cd changer can cause HUGE parasitic current draw when it starts to go out. If you have one equipped on your vehicle I would start there, it can be disassembled and the changer part unplugged from the rest of the unit.
Factory amp is also a source of power draw when the car's off. Do the basic test and disconnect the negative power cable after you park the car. If it starts fine after a couple days after re-connecting it, you've got draw problems.
The tougher part is narrowing down where that draw is.

Thanks for the replies guys!!
ive got an auto electrician coming this week, but at least I can give him some pointers where to look!

hope he can find the issue!
