Nice find bro!!! I know that alot of people use the honda 51R battery and love it, but that one seems even better. I just wonder what the CCA are on it? But either way, very nice find.

Zach

 

hoping you guys would like that. id get one but i ahve a perfect honda battery in the garage since i have honda **** all over with my mazda crap

Would you happen to know which of those batteries that you showed would be the one to use for our FD's?

 

Do a seach on 51R batteries. 10lbs lighter than stock. I've got bolt-in SS trays that fits FDs like a glove.

Jeff

 

Jeff,

Jon (SCRX7) linked me up with your new tray batch that you are making and I'm planning on picking one up. I wasn't sure of the availability of them though. Wanna clue me in??

Zach

 

this one is claiming to be 50 lighter than a stocker battery for the 51's and it will have more power. just have to use my free on first

I think Oddysey PC680 is good enough.
That is what I got, made my own alluminum tray. To fit like n-tech kit...gotta start the car every two weeks though to keep it alife...

If the 680 seems a little punky to you (you basically get one start) try the PC 925. You still save about 20 lbs over stock, and it is alot smaller. won't quite fit w/ an M2 large IC, but you'll save alot, and can fit in a trimmed-down stock battery tray. Can be had for about $100.

 

That's a nice battery. Would it work w/ the FD?
Anyone trid those Dynabat batteries. They're pretty small. I've seen one on an FD before...

 

I wouldn't bother with the Dynabatt. It's essentially a rebadged Hawker Genesis battery for twice the price. The Genesis (G16EP)can be found for around $70.

I'm working on getting a group buy started in the group buy section.

Keep your eyes open for it.

Thanks,
Jeff

 

what small batteries can fit in the rear bin (without cutting) besides the odyssey pc925???
its dimensions are approx w7 h5 L6

 

Just wanted to say Jeff's trays rule!!! Can finally pass inspection now at Autox with the new battery all tied down.... Fit perfectly and built well...

 

This is same size as the #680 used in the N-Tech kit. (nick was going to use the popular #925 26ah type, but I got him onto the lighter 680).

It's rated at only 280 cca's and 28 min RC. The 51R is about 500 cca's, and 80 min RC.

The #680 type batteries should have an internal metal jacket, for higher temperature rating for under hood use. Also convenient to get with sae posts, about $12 extra in this link.

http://www.batterymart.com/battery.mv?p=ODY-PC680MJ

this type of battery often does not come with metal jacket or sae posts.

 

I am using the 680MJ and tried to buy the replacement kit from N-Tech but he wouldn't sell it to me, since I didn't buy the battery from him.

I almost bought the the 925 ("link") but it looked even shallower than the 680 and I wanted it tied down. Well I had to use a hockey puck to tie down the 680 but it still comes loose with sprited driving and I don't have it tied down at all now.

TurboJeff: How bout making a tie down kit for the 925 and a relocation kit for the Honda 51R battery to the rear bin?

 

I don't know if the market is big enough to warrant making a 925 tray.

The 51R is a standard lead-acid battery, not really a good idea to have that inside the car.

Jeff

 

i am curently using the PC680, and i am going to be changin to the 925.

 

I bought the 680 instead cause I thought I could hold it down, else I woulda bought the 925.

Lead acid? Yikes, no way am I using that then but what about the sealed Miata battery for your kit? http://www.batteryweb.com/miata.cfm

 

In the bin or in the engine compartment? I've heard some guys are actually using it in the engine compartment with my tray. So it does fit from what I've heard.

Jeff

 

Just in case anyone's interested, I made a few battery trays for my PC925 before I moved it into the storage bin... they fit the 925 perfectly when it's mounted on its side, and allow you to use the stock tie-downs.. If they'd be of interest to anyone, I'll give them away for the price of shipping. You can see pics HERE . PM me for more info.

 

what are the benefits of the SAE terminals?

I plan on relocating the battery...should I go through the trouble for the metal jacket? if i don't get SAE terminals (someone explain these...are these the ones i'm used to seeing on all batteries)

how do I use the screw on type?

 

what's cca and min rc? what #'s are good for the fd?

 

FYI, Beware when you switch to a small battery, you might run into problems. I use the odessy 680. When i let the car sit for 5-6 days, I have to jump or re-charge my battery just to start the car. I think it's due to the factory alarm's drain on the battery. Although, I could be wrong and have some other battery drain elsewhere.

 

how come you have problems, but hondas don't have any starting problems and they come w/ small batteries stock? does this have to do w/ cca whatever that is?
