12V racing battery recommendations
 

I'm sure it's been covered before but looking for a lightweight 12V battery recommendation over my current Optima red top battery that weighs 38 lbs

Re: 12V racing battery recommendations
 

How much do you want to spend?

Re: 12V racing battery recommendations
 

Keeping it reasonable like $300 or under
It is only a battery after all

Re: 12V racing battery recommendations
 

I actually just posted about this topic on my FB page. I replaced my Optima with a Big Crank ETX30L AGM this season. Weight is 24 lbs and is half the price of a Braille B3121.

I received an email for 8% off if you enter "8offaug" this month.

Check out AntiGravity's line of batteries.
I found out about them from some off road friends and they are really rugged and dependable.
And they are extremely light weight.
A couple of my customers have switched to them with great results. https://shop.antigravitybatteries.co...extreme-power/

Re: 12V racing battery recommendations
 

If it's feasible, I'd suggest being able to swap back (quickly) from whatever you get to your tow vehicle battery. The battery gods and Murphy get together and take their life usually a few rounds in. :-)

Re: 12V racing battery recommendations
 

This is a subject on which I have experience and thoughts. With my super stocker and my bracket builds, 16 volts has been my choice for a few years.

However, I am softening with that stance and now think a conventional, lead-acid, or AGM 12 volt deep cycle is an overall excellent choice.

In my opinion, the latest, high tech batteries are not yet completely developed to be 100% dependable in the later rounds that come close together when charging time has been little to none..

The Camaro I am building today will have a 27 series, lead-acid, deep cycle battery. It will cost about $110.00, run the car all day, but carries the penalty of weighing 50 pounds. It is trunk mounted and in this situation, the weight is an advantage.

Lifeline Batteries. Their race batteries are made in the USA and built to MIL-SPEC since the company also builds aircraft commercial and military batteries.

Been running odessey for the last 8 years never had any problem and they are not expensive

Re: 12V racing battery recommendations
 

I have used two 11.5 lbs Braille battery's for years in the six pack car with zero let downs. Once the starter acted a little slow, battery was ok just a loose cable. My alternator works. I have tested and could go three rounds without charging in between rounds. I did cool car with sprayer until temp was reached then turn off fan. I change them out every three years.

Re: 12V racing battery recommendations
 

I used to run the optima batteries because they would last forever but they weigh a ton! Recently switched to the Odyssey batteries and have been really happy so far.

Re: 12V racing battery recommendations
 

I ordered the Antigravity! Thank you Tom!

Re: 12V racing battery recommendations
 

Which one did you go with?

Hi Glen. The xtreme power 10 cell.

Re: 12V racing battery recommendations
 

Interesting. This is the battery I use in my PWC. Does it have enough power to run the fan and water pump for a decent amount of time?

Re: 12V racing battery recommendations
 

I think you will be happy with it .
Just be sure to follow the charging instructions.
Like any battery ,proper charging rate and voltages are key to longevity.

Re: 12V racing battery recommendations
 

Sounds like you and I have exactly the same battery experience, Larry. This is the 4th season on my two 11.5 lb Braille batteries. I even completely killed them once last year by leaving the water pump on for 5 hours...discovered this fact when they called us up for first round. Charged them for 15 minutes or so, the car started, and I still beat a few people to the lanes.

Re: 12V racing battery recommendations
 

A few years ago my car wouldn't start for the semi finals at a race and I decided that this was not going to happen again.
Now between rounds I run the fan and water pump from the (2) deep cycle batteries in the trailer normally for the winch and jack. I run 4 ga cables to a switch box and then 4 way cable to a 4 pole plug. The 4 way socket in the car is wired in parallel to the normal wires.

Re: 12V racing battery recommendations
 

Made 13 passes Saturday with a single Group 31 in the trunk, 105amp GM alternator supplying the juice, never had my charger out. Doubt there are many cars using as much power as mine:

Dual stock GM F-Body fans, over 20 amps each.
Mezier electric water pump.
Weldon EFI fuel pump.
8 injectors, though they take very little.
4 coil packs (DIS waste fire setup, like a GN).
The last two hours ran the electric fan on the 2nd trans cooler, not sure what it draws.

The last 6 passes were made 15 minutes between each, only got to the trailer for fuel.

So....... Why mess with these little batteries you have to worry about charging when there are massive batteries out there that will never give you an issue?

Re: 12V racing battery recommendations
 

I run one or two Walmart budget batteries (either 26 or 56 as I recall)
that weigh 26 Lbs. I have been for 25 years. Easy to exchange on the
road if needed. They have recently gone up to $49.95.
I do charge them in the latter rounds.

Re: 12V racing battery recommendations
 

Because in Stock, we have to keep the battery in the stock location...a group 31 on the nose of the car wouldn't be too smart.

Re: 12V racing battery recommendations
 

I understand that. I have wired Stockers and kept a small battery up front to meet the rule, and put a real battery in the back that I never had to worry about. You're right, I can't imagine a Group 31 under the hood of anything but a truck! :)

Re: 12V racing battery recommendations
 

Stock the batteries MUST be exactly the same size. NOT just same brand and similar model. I got bounced for less than 1 Inch difference in length and same width in the same brand and model. This was in St. Louis
at Divisional last year in my Demon.

Re: 12V racing battery recommendations
 

Was the smaller one in the front of the car or the back?

I haven't seen the deep cycle batteries last much more than 1 year. Maybe I get the wrong ones. :confused:

Re: 12V racing battery recommendations

Re: 12V racing battery recommendations
 

Amazing! With all the other stuff going-on in Stock Eliminator they are worried about a battery.......... Guess it is easy to measure and check, unlike a lot of other "stuff"...........

Re: 12V racing battery recommendations
 

That is splitting hairs. Seems a bit picky on that. I could see if it was a big difference. Looks like they were hunting something to bounce you which is surprising as many racers as you have helped over the years.

Re: 12V racing battery recommendations
 

I work on electric forklifts and other small electric powered equipment and deal with deep cycle batteries daily. In a race car if you can handle the weight run a AGM 12 volt deep cycle and forget about them for 5 years or more. I have had good luck with deka brand group 24 AGM batteries. Weigh 45# each. I had a pair of them in the car for over 5 years and then moved them to the trailer and they are still powering the winch, lights etc. Plus you can leave them for months and still hold a decent charge.
Years ago had good luck with optima brand but at some time there manufacturing was moved out of the country. After that they did not last as long, not sure where they are made now or if that problem has been corrected.

Re: 12V racing battery recommendations
 

Well, there is that tree in Pomona...right John?

Battery size is one of those areas that racers seem to receive some latitude on....but I’m all for letting sleeping dogs lie.

Re: 12V racing battery recommendations
 

St Louis was one of very last divisional races of the year....We had to go back to fix some damages to our average (Thanks to other folk's performance). I had not been back East racing for many many years.....I got the impression from the extended time spent going over my old car (Raced since early 90's) that I was not getting thru Tech unblemished. It was easy enough to go to Walmart and buy two batteries!
Perhaps the Tech guy was a tree hugger and mad at me for the tree destruction like Jim said ( Only God can make a Tree but any Fool can knock the darn thing down ).

Re: 12V racing battery recommendations
 

These look good and definitely weight savings. How long is the charge time on these? Are they ok with alternators due to the fact that they require lithium ion chargers? Also, has anyone else heard of fires stemming from lithium ion batteries? I know a pro stock team had one a few years back.

Re: 12V racing battery recommendations
 

Bobby ,No problems with running with the alternator according to the manufacturer ,and I have seen none on the cars that I know are running them.
They should be charged between runs with the correct charger.
I have not heard of anyone having problems with these particular batteries, however ,I recommend that they be completely disconnected for storage and transportation between races.

Re: 12V racing battery recommendations
 

Paul do u have to use their charger?

Re: 12V racing battery recommendations
 

Nope. I use an el-cheapo Schumacher.
