This is a light weight battery that I hear has been used for street cars. Just curious, looking to relocate my battery to behind the passenger seat with a AGM type battery.

 

For a race car I wouldnt use them on a DD

 

You don't want any part of one of these batteries for anything that sees frequent use.

 

Thanks for the input.

 

Most don't even use them on a race car. Too much trouble. Yeah, they're light, but when your car won't start it matters not.

 

why do blind people need a car battery?

This has to be some liberal silly $hit to put labels on batteries so blind folks can tell what size the battery is in their car.....sounds like gov work to me..

 

I don't have any experience with Braille... but I have been using a 25lb Odyssey 925 in my ZR-1 for years, works great. I have mine mounted to the rear cross-member in a custom made aluminum box-mount.

 

Very impressive, My biggest concern is my car may sit for two weeks or more. I would likely use a battery disconnect however which would help. I want to relocate to rear passenger side compartment. I just sold an Odyssey that I ordered, weighed 43 lbs and had top posts, it didn't show top posts so I returned it.

 

I was pretty quick to say "you don't want any part of" BUT they're like any other product you "maybe" get what you pay for. The only units I guess I can say I was actually exposed to were very "light" compact units and I think there are maybe 6 - 7 choices in the product line. You weren't specific and I believe if you're actually interested you determine which model will fit where you want to place it and ask questions then about the specific product and the cable lengths, cut offs etc that you intend to use for the battery location.

Yours was maybe a very general question that got just "general" responses. I wouldn't have one but I've never considered one either.

 

Interesting mount Locobob. I moved my battery to the cubby behind the passenger seat. I used a piece of plywood to fit in the bottom and universal battery hold-down. I did have a Optima but after six years it had one too many complete discharges

I just bought a Sears Advanced Gold AGM Group 34 (cheaper than their Platinum series) for $148

Originally I was going to go the easy route and put the Odyssey in the behind the seat cubby hole too... but I race the car on occasion and NHRA rules require relocated batteries to be firmly mounted to the frame, they also require a kill switch which you can see in the first pic. It's a push/pull disconnect and it hides well just behind the bumper for normal use, for track I have to add a bit of rod length so it protrudes out the rear and a "push off" decal.

 

 

If you do decide to go the Braille route, they can be found under Dekka who is the actual manufacturer and can be bought for a lot less. A number of C6Z06 guys run this thing. I have the hunkin' Odyssey battery you just returned. Mine is located where the original gas tank was so it's good for drag racing.

 

I wish the website gave more info regarding dimensions and weight....

 

The Deka dimensions and weights are all here:

Braille is all right here:

The conversion from Braille to Deka "might" be these:

I know you mentioned an AGM type battery, but another option is lithium. I have a lithionics battery with a carbon fiber case. It only weighs 9 LBS, has never die technology, and can be shut off by pressing a button. Great for performing repairs. Unfortunately a separate lithium charger is necessary, but the battery can be charged in like four hours. However, if cost is a concern stick with an AGM.

 

Yes, very nice battery but 1000+ bucks? wow, it better last forever. I still haven't decided.

 

Personal experience: I have run the B3121 AGM battery in my wife's minivan for a couple years without a problem (daily driver) and I have several friends that have run the same battery in their C6 Vettes for nearly 3 years without a problem. Was even at a car show in Orlando a couple months ago and a guy there also had the same battery in his 2013 Viper and is the the battery he took out of his previous Gen Viper that he ran for a couple years. Another friend has an Ultima GTR with LS1 and he has run the B3121 in it for a few years, as well.

If you are looking for a lightweight, longer lasting battery, I recommend their GU1R lithium battery. It is 6.6 pounds and has V8 starting power. I replaced the 55 pound Group 49 lead battery in my BMW 540i 6-speed (daily driver) with this battery at the beginning of summer here in hot Florida, so I've got 6 months on it already. It started the car more quickly and runs better, which is one of the benefits of lithium since it runs a higher, cleaner voltage. I have had the car sit for 2 weeks while out of town (has security system) and had no problem starting when I got back. Now, being lower capacity (which any lightweight battery will have), if it was going to sit for more than 2 weeks, I'd put the 2 amp lithium charger on the car. (combo for battery & charger) I recently talked to a factory race team who had a Braille lithium battery, new in box, that was their "spare" battery and was sitting in their parts cabinet for 2 years. They checked the voltage and was still at 13.5 volts! So, it can be an added benefit if you plan to store the car & don't want to put a charger on it (or can't), you can either disconnect the battery at the positive terminal or install a power disconnect switch, remove any drain from the battery, come back a year later, flip the switch and fire it up. http://www.braillebattery.com/index....ies/gu1r_combo

My buddy, Dan Binks (crew chief at Corvette Racing in the ALMS series), is a big advocate for Braille lithium. He told me he used to go through over a dozen AGM/lead batteries in the team cars each season and just finished their 3rd season with the same Braille lithium batteries. They were recently tested and were still within spec of what they were brand new nearly 3 years ago. It is also in the new C7R, then again, they do use the ML30C battery at $2k each, but have never had a failure in 3 years of racing in those cars.

So, there are some "real world" experiences that I hope help. While there are plenty of options and depending on what you are looking to do with the car and budget, it may or may not be the best option.

 

I opted for the Odyssey PC925. The cost was reasonable and still a very good option regarding weight reduction. I am relocating behind passenger seat. Maybe the cost of the lithium batteries will drop as they become more popular with everyday drivers. I also got one for my 72 along with the aluminum hold-down brackets.

 

It's interesting in how they "dimension" that 925 battery. Dimensions are with the battery "on it's side"! That I'd say is a reasonable buy. I might have guessed maybe a little more warranty but the specs certainly show well.
