(2010 Infiniti G37 convertible)
Since last year, If I leave my car in the garage for more than week.. or 10 days, I come back to a dead battery. I have noticed, that every time this happens, there has been some initialization to the convertible top in the back where something has gone up or down without me trying to initiate the top motion.
My guess is something in the back moves, that drains the battery but I am not sure. Anyone got any suggestions as to what it might be? And how to resolve the issue?
Thanks guys.

Pick up a battery hydrometer and test the specific gravity of the individual cells



Any cell not accepting a full charge, replace the battery.

^^ exactly what he said

With the age of the car and assuming it's the OEM battery I'd just replace it at this point anyway.

I have the same problem, but an 08 G37. The dealer said that since I only drive very short distances anymore the evap valve test mode never gets a chance to cycle through. And when I shut it down and leave the valve is still trying the finish the test cycle, hence the constant dead battery when I leave it parked for 6 or 7 days
. Had me scratchin my head

From my experience, the battery on G37 last about 3 years.
I have 2 G37 (sedan and convertible) and after about 3 years, the battery must be replaced because don't hold the charge, especially in the winter.

I am the original owner and just replaced the OEM battery in my 2009 G Vert last week (after just under 7 trouble-free years)

Before I bought mine, a service tech said to start and run your car every couple of days if you don't plan on driving it a lot. Something happens with the top. It's not good anyways for a car to sit without being started or driven.
