There is a larger size that will fit, it has even more capacity than the one I have now. I will find the size and post it for you.That is cool to see you have a larger battery than stock size. Based on what you said here, is there another larger battery that can fit here? Is the battery more heavy duty than this one you have installed?
Now that I have these auxiliary lights installed on my QX and they all work directly from my battery, I figure I need to start looking for a more heavy duty battery before I drain my current oem battery that was installed brand new 3 years ago. It may be coming to the end of its life soon, though I cannot tell yet as it seems to be performing flawlessly so far. But I am sure I will need to upgrade soon and I would like to make the sacrifice to buy the most powerful heavy duty one that can fit in the battery tray on our cars.
Do you know of any battery that is more powerful than this that you just installed that would fit on our QX? I may be interested in looking into maybe buying one some day down the road.
I plan to buy it in the future and move this current battery to be the secondary battery behind the driver seat. I won't do that though until I start building the cabinet/drawer system.
