My 315s on the CCWs (I have C16s - [got a deal, long story] and Alex has Classics, so I have about a 1-2 pound per wheel advantage) weighed 47 pounds. At least I will beat him on SOMETHING!!!!

As for the alternator, it isn't much bigger than a softball. If was any small, it would be an idler pulley !!!!!!!!!!!!!!!!!!

Anyway - next are pics.

I lost 20 lbs in each seat with NRG fixed back seat from *bay. Another 20 lbs replacing the Walmart battery with a Braile 15 pounder.

Have you lifted a wiring harness in a modern day car? They are really heavy.

They must have weighed 5-7 pounds each. Seriously, with the tracks removed my seats weighed right at 28-30 pounds. The 14115 I installed weighs 11.5 pounds and replaced the OEM 36.5 pound battery.

07 Sky seats with no power weighed 35 lbs on the digital bathroom scale.

Well, the Braille is installed. And it was almost dead.

Jumped it just to get things going, shut it down, and put a light charge on it - per instructions.

Here is all the stuff. The adjustable hold-down and L-screws came from O'Reilly's for $12.

Installed. Note the bit of thin foam as an anti-skid piece.

This shot shows a screw I installed to keep the pieces from slipping.

The supplied terminals are a bit more tapered than the OEM terminals. This meant that I had to really get the clamps snugged down well before tightening the terminals. Then the terminals were not quite tight enough, so I held my breath and snugged the supplied Allen screws a bit tighter. The wing nuts will be replaced with higher quality nuts and washers. But it is all tight !!!!

Maybe two months (that's how long it's been since I weighed them) cost me 5 pounds. In any event, Kirkeys weigh a minimum of 12 pounds plus a couple pounds for the cover. Then there is the weight of brackets.

I'm surprised you installed it up and down. Better CG on it's side.

Actually, the cables will not stretch that far. And it DOES sit very low in the car, doesn't it ?!?!?!

NormSky · « **Reply #32 on:** July 08, 2010, 09:20:06 PM »

They'll stretch. That is how how I installed mine. Just have to take up some slack to make it. I take a pic tomorrow and post.

snaponbob · « **Reply #33 on:** July 08, 2010, 09:25:45 PM »

Did it to get where they are now.

NormSky · « **Reply #34 on:** July 09, 2010, 11:51:12 AM »

My Braile B2015 mounted on side with cables stretched.

snaponbob · « **Reply #35 on:** July 09, 2010, 12:24:43 PM »

If mine doesn't stay put (I expect it will be okay), I'll look into laying it down.

you use your kappa for everyday use?
i m looking forward to getting my one Braille but i am concerned if this battery is actually for daily driving and if all parts will work perfectly with it.
pls let me know of your experience

NormSky · « **Reply #37 on:** July 09, 2010, 02:11:53 PM »

SKY888 uses the same battery as I do and uses his car year around with no problems. I used mine for most of the year.

Arabas · « **Reply #38 on:** July 09, 2010, 02:20:45 PM »

i see Normsky! so you tottaly suggest this product?
the metal piece that locks the battery in place, does it come with the battery or is it optional?

NormSky · « **Reply #39 on:** July 09, 2010, 02:32:13 PM »

You buy just the battery, mounting bracket is extra where I made mine, Bob bought his at an auto parts store.

Arabas · « **Reply #40 on:** July 09, 2010, 02:53:38 PM »

thanx Norm!
one last question, why choose B2015 that according to Braille in temperatures below 50F is reccomended only for racing, instead of B2317 (only 2 pounds heavier) that is reccomended by Braille for daily driving too at temps below 50F?

NormSky · « **Reply #41 on:** July 09, 2010, 03:11:19 PM »

Not sure where your getting the 50F stuff but Sky888 lives in one of the colder climates in the US. Besides mine overnight in the garage. Those Lithium batteries look nice for $1900.

Cranking Amps 30 sec @ 32F: 574
Cold Cranking Amps 30 sec @ 0F: 425

Norm, if you click on the tab "applications" on the page you sent me, it shows the information on the 50F i was talking about.
i like this battery and i m getting all the feedback i can get form you guys that have used it.

NormSky · « **Reply #43 on:** July 10, 2010, 08:20:24 AM »

I see how your computing the 59F for recommended for racing only.
