Auto-X Smaller Battery?
�
�
How many of you Auto-X or track guys use a smaller (lighter) battery? Any starting problems?
How quick does a battery changeover need to be to avoid re-setting the ECU?
Responses appreciated...

i think ant disconnecting of the batt will re-set the ecu, but dont quote me on that. as far as batt size, a bunch of people have been running optimas and other super small batteries. ill have to go look and see what the small one was, but no one in my regions had any issues.

I used a Hawker Odyssey battery in my D Street Prepared Integra. I think it was about 14lbs. It was a drycell so it did not need a battery box to be legally mounted in the trunk. It also came with a mounting bracket for the trunk. Nice battery.
They also have some 11lbs batteries that are little lighter on cranking amps. You might run into charge problems if you have to restart the car a couple times in a row. Though an autox run should be enough to keep it charged. A backup powersource would be recomended.

I've got a 12.5lb Hawker Odyssey PC545 in my 99RS. It doesn't start too well when it's really cold out (especially if it hasn't been started in a couple days), but otherwise starts as well as the stock battery did. (EDIT: I just noticed you are from Florida...you should have no problems with this type of battery in that climate.)
If I had to do it over again I'd go with the PC680 (about 2lbs heavier, more amps and has the option for SAE terminals (ie. battery posts)) or higher. Even two PC545s in parallel is still notably lighter than the stock battery and has tons more cranking amps... :lol: (Of course, many of the autocross classes don't allow changing the # of batteries from stock so you'd need to pull one for autocross if you went that route.)

I have a Hawker Genesis, which is about 13lb. I was intending to put the stock one back over the winter because I was concerned that the car might not start, but now it's gotten fairly cold a few times already, and I never had a problem.
I don't think the ECU resets immediately when you disconnect the battery. That's why the reset instructions normally tell you to stomp on the brake pedal for a while. In either case, there shouldn't be any harm if the ECU gets reset. It learns quickly. I have reset mine a few dozen times.

I got the same battery and I thought I might have to do the same witht he cold weather but it's down fine. The only difference is that it doesn't last as long witht he car off and the radio running.

Now that you mention it... I had the radio on while sitting in the car during the great flood on the first day at Nationals. Not for all that long, I thought. Then the radio display and everything else in the car suddenly started blinking. I tried to start the car, and nothing at all moved. Needless to say, that happened when it was about time to pull into grid. :furious: I went to look for my codriver to tell him that we were in trouble, and when we came back to the car... it started without a problem! :D
I think I got exactly the battery that Pat linked, bought from the same place. Including those battery posts. The stock tie-downs won't work directly because the battery is much smaller, and they are not threaded far enough. You'll have to find shorter ones, or you could probably add some kind of spacer. The battery is small enough to be mounted flat.

You can mount the battery flat, but you need new wires because they're too short.
I just use the stock parts to hold it vertically. Just put the battery in the center and tie it down like a regular battery. It doesn't move at all, but those damn tech people at autoX always want to tighten the nut some more for me. :furious: :disco: :furious: :disco:

OK, call me a retard... but what are the SAE battery posts for?
With the continuous warm weather out here in Hawaii I think I might go for one of these, too. Of course, I just bought a new DieHard about 3 months ago. :rolleyes:

how much weight savings are we looking at here? sounds like a good idea, but not sure if its worth being stranded.
| TheWRX | 01-03-2004 09:03 PM |
Pat O.: You attach the posts to the terminals (using an allen key), and then you can connect the stock battery cables to the posts, exactly the way you connect them to the stock battery. I'm not sure how easy it would be to connect the cables without the posts. You'd probably have to fabricate something at least, I doubt that the clamps on the stock cables would work.
loreley: I believe the stock battery is something over 30lbs. So the weight savings are about 20lbs.

You're talking about your RS? Because it doesn't for the new age WRX. I was told I need to get forester or legacy starter cables to mount it flat.

I thought a lightweight battery was a common mod in stock classes but it is not listed here [url]http://moutons.org/sccasolo/Rules/stock.html#s13[/url] which is a pretty dependable source for scca rules. And if its not listed its not legal.

I would have assumed non-stock batteries were fine in stock as well but you are right, it isn't listed thus not legal.
It IS however, legal in Street Touring/Street Prepared or higher (you can't change the voltage or the number of batteries, but the amperage, size, etc. is free).

Yeah I assummed the same thing I was surprized when I could only find a change of battery rule in st/sp classes.
| dwx | 01-05-2004 06:27 PM |
It's not legal. Dave Bruener (AS STI driver) had a lighter weight battery in his car at Nationals and had to find a stock Subaru battery from someone to put in the car.
I have a relocated battery now but it's an Optima Red Top. Those batteries weigh something like 43lbs. I'm definitely going to be using a lighter weight one for autocross this year. 30lbs is alot of weight savings from one source.

I figured out you dont need "hardware" for these smaller batteries... Just use a few extra larger nuts or a holowed metal tube depending on the type of battery to lower the point that the stock brackets hold the battery in. And back it up with some double sided sticky tape. I did that with my 13lbs battery and its in there really nice :D

Is the Braille a gel cell battery? The #'s posted in the pdf look good, but wondering what the other companies would say on valid comparo's.
BTW I got my Odyssey 680 w/ metal jacket for $86 shipped w/ the posts from odyssey world on ebay- got in three days.
I think I'm going to mount mine on it's side and fab up a little heat shield for it.

Very nice. Came with everything I needed. I can send you a link where you can get them for $125 with everything you need shipped to your door.
Install was a snap. I already put one in the STI and another is going in the SRT-4.

Is the braille actually that much better than the competition? It is certainly more expensive. Are any of these batteries going to be able to start my car in below zero Maine weather?

Can't comment on the Braille, but these smaller batteries are definitely "summer" batteries- unless you happen to live where "summer" is a near year around event.
Mine will come out in the fall (our racing season wraps up early Oct) and in w/ a new Optima (the stocker is three years old). We routinely see a couple weeks where we never break 0-even w/ the car plugged in, it takes a pretty good battery.

[B]Is the braille actually that much better than the competition? It is certainly more expensive. Are any of these batteries going to be able to start my car in below zero Maine weather? [/B][/QUOTE]
Can't comment on the Braille, but these smaller batteries are definitely "summer" batteries- unless you happen to live where "summer" is a near year around event.

[B] It's not legal. Dave Bruener (AS STI driver) had a lighter weight battery in his car at Nationals and had to find a stock Subaru battery from someone to put in the car.
I have a relocated battery now but it's an Optima Red Top. Those batteries weigh something like 43lbs. I'm definitely going to be using a lighter weight one for autocross this year. 30lbs is alot of weight savings from one source. [/B][/QUOTE]
Hey Phil- so I take it a smaller/lighter battery is SM legal? Hmm, with the motor out, wonder if I should go ahead and reloacte the battery. What is involved and what do I need to buy ad where to get that hooked up man. And yes, I'll search for battery relocate too ;)

Battery changes (and battery relocation) are explicitly allowed in both Street Touring and Street Prepared (and Street Mod inherits both rulesets). Note that you cannot change the voltage or number of batteries however.

Has anyone actually weighed the components used in a battery relocation? It seems that with these incredibly light Braille & Optima batteries, relocating your battery to the trunk would result in only marginal performance benefits. You lose about 20 pounds (or more) by switching the stocker for a lightweight. I can't imagine that proper gauge cables would weigh any less than 5-10 pounds (what does a good set of jumper cables weigh?).
If you already have a car corner-balanced & prepped to the limit and now you're relocating "ballast" for optimum weight distribution I could see doing this.

The relocation isnt about optimum weight loss its about best weight distribution. You get anonother 11 pounds off your front end and add a little bit accross the car and 11lbs in the trunk.

Can anybody recommend a good battery relocation kit?

Here's the one I just got:
[url]http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&category=46098&item=2469845746[/url]
It worked pretty good. The bracket setup didn't seem to be part of the kit, but it would work. I just used the factory bracket setup.

60$ shipped.
Anybody know how much relocating a lightweight battery to the trunk or cabin will affect the starting of the vehicle and charging of the battery?

Has anybody started a group buy with gotbatteries.com to get the price of the Hawker Odyssey to $59.95? I would think that getting 10 interested people would be pretty easy...especially if the price goes down $10.
| ChrisDP | 03-29-2004 08:26 PM |
I got a Hawker Genesis, didn't get the SAE terminals with it. I disassembled the Pos terminal from the stock cables, screwed the cables that lead into the terminal directly to the battery. For the negative terminal, I disassembled and used a pair of tin snips to trim the stock. The stock terminal tightening bolt was removed, I just cut the terminal so the hole for the tightening bolt is now used to clamp to the terminal. Seems to work great so far.

No reason that shouldnt work. I just like the post better. Ive had some bad experiances with batteries without post.

afpdl - So I assume you are rating weight distribution over absolute weight loss? You're still gaining back 5-10 pounds of distribution cables by relocating. Just curious.:)

My battery is still in the front Im not rating anything over anything. Just stating on why they move the battery. I dont know which is better to have(less weight or better distribution)

Like I said -- just curious. Trying to figure out the best compromises.
