Iv'e had the Braille battery installed for two years (40,000 miles)without any problems. My ride is an 08 LS3 with the battery relocated to the passenger side cubby hole. FYI... My battery dimensions are 7" long...6" high...4" wide. I don't remember the weight...but...17 lbs seems to ring a bell.
The Braille and Deka are the same battery, except for the stickers, and you paid more for the Braille. EastPenn makes both, and also makes them under the Big Crank label. 17.5 pounds is exactly what mine weighed so we definately have the same battery. The Braille is available with a carbon case on certain models. Other than that it is identical.
About the concern that if you leave your car for 6 weeks the battery will be dead.
My OEM battery was dead after sitting for 8 days at home and the dealer replaced it under warranty but before replacing it he told me not to leave the car sitting for over a week due to the high current draw of the electronics.
I was considering this battery with a relocation to the rear to make room for a larger supercharger coolant tank but the "old school" in me just can't get over what you give up in performance. Even the so-so factory battery is 590 CCA and 110AH. I guess you could make the arguement that newer cars with better fueling and ignitions no longer need the extra "umph" to start but this battery has 1/2 the cranking amperage of the stock battery and an even lesser fraction of reserve capacity.

That's a very conservative rating. Braille rates the same battery more optimistically.
That said I wouldn't recommend the ETX18L for a rear cubby location because of the long cabling and increased resistance, although several here have done it.
One of the reasons I chose this model is because I mounted it in the stock C6 location. I was trying to reduce weight, and by the time you add cabling for a rear cubby location and thereby increase resistance, you should probably choose a larger battery (some members here have mounted the ETX18L in the rear with no problems). You don't wind up saving much (if any) weight. Check the title of this thread.
I've had many members pm me for details about my battery install so I've made a miniature "how to" with additional information. PM me if you want a copy.
I live in Southern California. I drive my car at least once a week, but the car did sit for three weeks without being charged and started up fine. I've had this battery for over a year with no issues.

I thought that was ridiculous.
If your car sits for 6 weeks at a time I wouldn't recommend the ETX18L (or any AGM battery) unless you use an AGM-specific charger. NOT a normal or trickle charger, but an AGM-specific charger. High current draw is nonsense IMHO.
I already had a CTEK battery tender. its good for AGM. There are at least 2 dozen threads on using a battery tender for these cars. thats why i use one. Deka battery is fine going on 6 weeks. heat of houston 100+ F heat index for several weeks now.
My SC car has:
aux fuel pump
1800 watt stereo
methanol pump
these aren't powered up on start up.

FYI...You can't mount a regular size battery in an 08 rear passenger side cubby without removing some electronics. The 05,06,07 passenger side rear cubby is large enough for a larger battery but not the 08. I would love to save money and I will definetly look at the Deka batteries next time around. Braille makes a 17lb battery as well as a18lb...slightly different dimensions and cranking specs. By using a good grade marine cable (4 guage) you still save weight, but more importantly you change weight (BALANCE) transfer to the back wheels. The battery also stays cooler when removed from the engine compartment...should last longer.

There is another factor. Some batteries are made for interiors (non-gassing) and some aren't. Just pointing this out.
I understand that moving the battery to the rear can help with balance. I agree that the battery is cooler when removed from the engine compartment, that's why I wrapped my battery in heat insulation shielding. Life is a compromise.
Hate to bring back an old thread, even if I do think its super informative. But I am getting ready to buy this battery for my 08 z. Can someone give me the model number or confirm that this is the one I need
also will I need anything else terminal wise for this battery. I wont be laying it down as the OP did because mine will be in the stock z06 cubby hole location so It will be standing.

That's what I bought, and from the same vendor as well.

you will need the adapter posts so the stock Z06 OEM cables will fasten
yep correct # I have it in my C6. my cubbie is vented because of the cables coming to it... so if the stock Z06 cubbie is vented, no prob...the battery comes with vent tubes BTW
The way I have it mounted (on its back) it is 3.5" tall, 8" wide and 6.5" front to back. Stock battery was 6.75" high, 9.5" wide and 6.75" front to back.

Thanks for the write up. after so many years, this battery still seems to be the best lightweight solution unless you want to spend $300+ on a marginally better lithium unit
