Just wondering what battery and size will help lose a little weight and will fit in the stock tray?

I am not trying to lose performance and worry about having to constantly trickle charge it.

Deka is down the road from my house too.

I'd suggest draining your washer fluid. Easier to do and free.

Run a quality battery and don't fret the weight.

If you must. Look into Optimum.

TT>GT2>GT3 in terms or capacity which should equal weight, I'm sure there's a weight compare somewhere...but I'd try a GT3 battery if weight is concern but so is reliable charging...note that if you are running a big fuel system you might want to keep the biggest battery possible...

I ran a 12 lb unit in my 993 for yrs. The only down side is you must connect a trickle charger if the car is not driven for a few days & its cold out.

12lb battery only good in 45+ weather in most cases and if you leave your door open its donzo. Also if you have a built motor with big fuel pump and etc you might want to leave a good battery in there. Deka makes some in the 25lb range as does Brailie which is still half the original weight. Don't over think it bro, built motor, big turbos, who cares about 20lbs of weight.

The Braille battery at $225 is a Deka battery at $99 delivered, from Amazon, both are made by East Penn.
Some modification to the existing 996 Turbo battery tray is needed for the smaller battery costing about $12.00. Search will show it.
I have been using the small battery for quite some time and find no down side.

Battery is a 22 lbs Deka ETX 30L. They do make a smaller one [70L I think] which i know a member is using.

pretty sure pwdrhound posted a comprehensive review/install procedure that included the deka/braille connection. if you can locate that thread, you're in business.

personally i can't justify the loss of cca's for the savings of the few lbs. for the street anyway..i've seen too much electrical demand outa these. trickle charger and all.

With the Braille 21 my car can sit for two weeks and still start just fine.

amazing. i would never even test that. i trickle charge out of habit every cpl weeks but drive every day. that's the best way to keep it charged

Yes, I have to thank powdrhound for the inspiration, I wrote :-

Excellent write up and pix - thanks. It inspired me to look into doing the same - particularly as my Bosch battery let me down last Tuesday.
However, looking for deals I did some shopping around and found that the Braille battery [now $229.99 from Amazon] is the same as the Deka EXT30L, Big Crank and Magna Power batteries selling for $99.95 - all, including the Braille, made by East Penn.
Also, a similar mount kit to the Braille at $23.66 can be had from Pep Boys for about 1/3rd the price.

You mentioned that the existing -ve battery cable was just long enough and i see that you moved the Braille battery towards the cable end for this reason. I wasn't happy using the short OE cable and installed one about 4 inches longer, this allows the small battery to be in the center of the battery tray with no stress on either +ve or -ve battery cables. I see you secured the tee nuts with JB Weld, i used epoxy as i didn't have JB Weld, seems to be holding up well.

Thanks again.

You're welcome. I mounted the battery slightly off center in the tray which allowed me to use the OEM battery cables. When mounted off center both cables have just enough reach with a bit of slack left over. As far as the bracket goes, I had a Oddysey battery bracket that was made by another member here. I would not work for the Braile but I used the top bracket from it. If I were to do it again, I'd just buy some 1/4" x 1" aluminum stock, cut it to size and use that as the top bracket. Together with the bolts and T-nuts, your investment would be about $10.

Looks like the Deka is an AGM...... they are very sensitive to the top charge voltage so the Lead setting might be a bit to high. They usually last a much shorter time if even slightly overcharged.

I am running a big fuel system, honestly that completely dropped out of my mind for some reason lol......
