Odyssey PC925 install
The PC925 is another mini-battery option, and as the name suggests, it has more cranking and reserve capacity than the 680 mini-battery options. I've been wanting a short route UICP for a while, but didn't like the 680 mini-battery because I have a car alarm that sucks a lot of amps. I'm hoping the 925 will have enough reserve capacity to last as much as 7 days with the car off.
Anyhow, I've only got one picture to show thus far, but the install is pretty simple. This install is written with the intent of making room for a short-route UICP.
**Note: I have my doubts that this battery will work with the ETS short route UICP because of how close the intercooler piping comes to a PC680 battery setup.
Install steps:
1) Remove factory battery.
2) If you're planning to do a short route UICP, cut down the tray, and then reinstall the tray.
3) Disconnect the wiring looms from the metal brace that was attached to the battery tray. Removing the brace frees up the looms to make it easier to position the positive terminal on the battery. Use a screw driver to pry the tabs to allow the looms to slide off the brace.
4) The battery ground cable isn't long enough to reach the negative terminal of the PC925. I didn't see any obvious way to relocate the ground cable while still keeping it attached to the body, so I snipped the cable right where it attaches to the body and built a new ground with multiple ground locations. I used 8 gauge power cable, ring terminals, and a battery terminal from my local car stereo store. I think it added up to $55 in parts. Can probably get everything for $40 online.
5) Cut the battery hold-down brace slightly to keep it from being too close to the positive terminal.
6) Install the 925.
7) After I got the 925 installed, I ziptied the two large wire looms together to help support each other.
The PC925 is more expensive than the 680 battery, and a new ground cable is needed, but being able to use the stock tray saves some money. Overall, I'd say its about the same cost as a 680 option when using a brand name 680 batttery. The advantage is hopefully that the 925 going to last longer than the 680 option. If not, I suppose, I'll be moving onto a Miata battery...
Not the best install picture. I'll try to get some better pictures today.

I have been holding off on installing my mini battery for the same reasons. From the pic, it looks like you would have more room to slide it back with a different mount. would that give you a bit more room or is it just a illusion from the pic?
Looks great tho, I like it.

What about rotating it 180 so the terminals are on the other side. Seems like it would give it more room for the piping. I have a PC 680 and it sucks. I just leave it on a trickle charger. I've been thinking about trying the 925 so i can't wait to hear about it.

Yeah you might need to extend the wires a little. I have them reversed on my 680 and the wiring is tight. I just wouldn't like my uicp ring by the power clamps. I think you'll be hitting them with the short route or really close.

Its funny this topic came up because recently i was working on a friends build and i wanted to use a bigger little battery...I ended up with the 925 but i put together a tray to give me extra room for charge piping....the way i did it i was also able to use the stock battery cables with zero modification of them..
