Just replaced my battery in a dark Wal mart parking lot.


How the hell does the back of the battery tie down attach? Is there a piece that I am missing? I didn't see anything listed in the OEM parts, and also didn't take anything off other than the front nut.

 

There is nothing going across the battery like a bar?

 

There are two j hooks. The front one is long. Back one is short. You hook them at the bottom. Theres a blk bar that connects the two. Then you place the nut on top of each j bar. Tighten down.

 

^whs, you should do it in a lighted area so that you can get the J hook into the proper hole

This picture shows nothing in the rear. So there is another hook that is missing?

 

Meh, link doesn't work. You have to click on electrical, then battery to see what I'm referencing. I'd post a pic if I wasn't on a tablet.

 

Guess I should elaborate. It's early. I don't have a rear j hook, but makes sense that I should.

You can see the J-hook in the pictures provided in step number 5.

 

Am i the only one that does not use the tie down bar?

I don't track my sedan or coupe, so the bar is useless

 

I think the point of the bar is to keep it from bouncing around when you hit a large pothole or something...it's not necessarily there for tracking a sedan or coupe. I'm sure you also go through speed bumps and the battery tie-down is there for a reason. If it wasn't needed, Infiniti wouldn't put it there. Plus, our OEM braking system isn't meant for tracking anyways, so there is a different reason for it being there. It's even on there for all cars, including non sporty ones like Toyota Corolla.

Battery contains sulfuric acid, and you don't want it to be oriented the wrong way and have it spill acid or something, especially when it's near the air vents for the passenger cabin. You also don't want it to cause a dent in your hood when it bounces. It's a simple preventative tool to keep battery still.

Plus, the battery tray is actually larger than the OEM Group 35 battery, so there is some free play that the battery can move around on the tray which makes the tie down bar even more important. Also, you don't want to stress the wires that are connected to the battery as it's moving around. I know the positive terminal cable is pretty firm in terms of free play.

 

dont hate on corolla's man! na just joking man! All that bar does is possibly prevent the battery from bouncing around and causing damage. mathnerd88 is correct

 

With a loose battery, if you ever have to slam on your brakes in a full panic mode, or if you do actually have a low-speed fender bender in the front, you will most likely be looking at repairing some damage in and around the battery compartment from what is essentially a large lead weight (pendulum) that's floating around in there. Additionally, when the battery slams into the sheet metal, it is very likely to fracture its plastic case and leak acid all over the surrounding area. That is corrosive and will cause rust in places you likely can't or don't want to try and get to. EVERY automobile on the road came with a battery hold down. It's there for a reason; USE IT!

 

No leaking here

 

Alright, you guys make very good points. i put the tie down bars back on both G's.
