I installed my mini-battery a few months ago, and it's been very reliable. The car sat for two weeks, and started up just fine.


I'll try to take exact weight measurements later, but the stock battery weighs at least 35 lbs. The shipping slip for the PC680MJT (with optional metal jacket and standard SAE automotive terminals) was 17 lbs.



Here are a couple photos to show how much space is gained, in an otherwise stock engine bay. The tray is made of wood, I'd like to replace it with a fiberglass or carbon fiber version if I can get ahold of the materials for cheap, but this works for now.






Here's a photo from the rear. It was nice to finally see the radiator!



If anyone has photos of their mini-battery setups, please post them here as well.

I just measured mine (with metal tray) and it came out to be around 14-15 lbs.

 

Where did you get it from, Home Depot?

You know that Rotary Extreme sells a polished battery tray, right?

 

Ack, seal off the battery tray feed..you are losing air to your IC and intake.

Man, I almost forget sometimes what a stock engine bay looks like.

 

SpeedKing, I don't like the idea of using metal for the battery tray. I've yet to find an OEM battery tray that isn't made of plastic, so I think it must be important to use a material that doesn't conduct electricity. The first tray I made used an aluminum strap to hold the battery down. After only a month of use, there was a significant amount of rust where the aluminum had been touching the frame. Besides, that RotaryExtreme tray is a bit too blingin' for my engine bay. I'd like to see more photos of that tray though, preferably a shot from above to see the orientation compared to the P/S and radiator.



Rynberg, thanks for pointing that out. I just bought a dremel, so I'll trim and seal that duct soon.

Ditto, I forgot it even existed.

 

It's not so much that they use non-metal trays in OEM battery applications for the conductivity reasons; it's mostly for the corrosion resistance. The plastics or FRP they use doesn't corrode when battery acid or any pole corrosion drips down onto it, so it won't fail and collapse under the stock battery's weight.

 

I have a Odyssey lying around my room and still havent installed it. Im too lazy to build my own box and dont want to pay rotory extreme $110 for a tray.

 

while we are on the subject about this battery....could you run two of these at one time. Like run them in series or something, or would that not work since the car is a 12v system?

 

You could run them in parallel, but why wouldn't you just get a larger battery?

 

Chuck's is a nice piece, but you can always use Jeff's battery tray he made for use with the Optima red top battery. It has the bolt down brace like stock which by the way, does anyone use Chuck's box on the track and pass tech inspection since the battery isn't supposed to come out, fly around etc?

I second the comment that OEM trays are plastic to resist corrosion. By the way Carbon Fiber is a better conductor than steel.

 

I've had this battery for a year and a half with no problems at all. I had to charge it back after my car was down for 6 months for a rebuild but after that it's worked every time. I've left my car for weeks at a time with no problem.

I ran wires from the battery down to the opening in the bumper and used a gm alt plug so that I could hook up a little 1/2 amp trickle charger but I've only hooked it up once.

Here's a nice pic of my engine bay:

 

The reason why I don't run a larger battery is because that's the only batery that will fit up front. So I was thinking about adding an extra battery(in one of the rear bins) so that I will have more power....just in case.

 

is it possible to run a monster vmount with a 51r battery?
just curious, it seems like it wouldnt work..but who knows

 

any of you guys running the pc680 running aftermarket ecu's or aftermarket alarms? My car would barely stay charged with that battery, a haltech and a clifford alarm system.

it gets pretty cold here sometimes and it wont start at all.

(installed optima red top last week )

 

I have a power fc the whole time with no issues.

 

I have several pc680 batteries i leave for long periods of time in cars without driving them. I was having trouble charging them back up with a trickle charge. I called the online battery place i bought them from demanding new replacment batteries thinking they where bad. the advice i received was to use at least a 6amp charger. He was correct, switching to a 6amp charger solved my problem.Hope this helps someone avoid what happened to me.

 

I have one for sale...pm me and make me an offer...I'm sick of looking at it...Kevin
