Car takes a bit of cranking to start for each move up in the lanes. I run no charging system, and have older electronics that don't handle 16v so I am stuck with either a 16v with a reducer as an option or a better 12v with enough reserve to go two rounds.

I borrow one of the optima batteries with more cranking amps and put in my car and it does not spin the engine as fast. Hmmm! Regardless of how good something works when it comes time to replace it I want something bigger,better more powerful! Like you none of our cars have a charging system maybe with the input from everyone we can determine the Best battery to use for cars with no charging systems! PS Mine must have a new battery,but if we can find a better battery we will go ahead and replace all of them! Last edited by MRMOPAR622; 12/29/12 02:07 PM.

Sometimes alky injected, no alternator, hard starting with 14:1 compression. Never left me setting in the staging lanes once. Not one time. I have the first one I ever owned that was bought in the late 90s that I still use in my plow truck lol. 67 Barracuda street/bracket car 11.27-119 68 Dart 502 BB 8.70s-152 414 cid SB Dragster 7.65-174

Same with the Dedenbear box I have. I do get reasonable service out of the Optimas, but have heard some guys complain about them. As far as performance, I don't see any deterioration in performance as long as I can get the motor lit and make the pass. The reserve of the Optima is ok, but when the battery gets to about 1/2 charge the cranking voltage gets too low for comfort. 8..603 156 mph best, 2905 lbs 549, indy 572-13, alky

I use Interstate's 1,000 amp rated...as long as I kept a trickle on them, they lasted forever with plenty of start power...no bigger than the Optima's..and a lot cheaper!

Everything I've read and seen shows that they are the same thing , just relabeled. Best of all, they are less expensive! I've had an Odyssey in my race car for a few years, but I also run a 50 amp alternator and charge religiously between rounds. Shortly after getting the Odyssey I found out about the DieHard Platinums, so I got a pair for my dually.

Have you looked in to "Braille" batteries? I think they are made by Interstate batteries. Very light weight ( 6 to 21 lbs depending on size / cca output ). Think I am going that route with my next battery purchase. Prices are in the $200 - $250 range. Fastest 300

Greg, I have the exact same setup, up to and including the same battery, the only difference is because I run a small alcohol fuel primer, the car starts very easy. Here�s a few posts on how it�s setup https://board.moparts.org/ubbthreads/show...rue#Post7483175 Joe Without Data, you’re just another guy with an opinion.

There are issues like you can't jump with a 12 volt or use your buddies jump box in an emergency where you forgot to turn your charger on. But, 16 volt batteries charge slow, 25 amps, there fore they do not charge at a high voltage when on their recommended charger. 16 volt alternators can charge much higher. And this is when you burn low voltage electronics up. The 16 volt batter fully charged is on about 16.6volts. once there is a load on the battery you are looking at 16.4 or less. There is nothing on any 12 volt system that will not handle that. The benefit of a 16 volt system are when not using an alternator you have good voltage to your accessories. Where a 12volt system with alternator has 13.5-13.8. With no alternator fuel pumps, water pumps, fans turn slower due to the limited 12.5 or less voltage. You can crank with a 16 volt battery and never have less than 11.5 to the ignition where it discontinues to operate. This is why 16 volt systems are popular. You can have a practically dead battery and as long as the engine cranks the ignition will work and start the engine. But, let that 16 volt get below 14Volts and it will not turn any engine with nutz over. So that takes some understanding. I run 16 volt because I already have the charger but there is nothing wrong with a 12 volt system if you have an alternator. Many racers do just fine with 12 volt systems and no alternator just be sure you are charged up between rounds. Career best 8.02 @ 169 at 3050# and 10" tires small block power.

I guess I'm also asking which is the better battery(most powerful) to use of the 2 a 12 volt or a 16 volt? PS Greg,I will see if I can find the name of the company in SC(he used to work for MSD before branching out on his own) I sent my MSD 7 to 2 years ago when I had a Hi-Speed miss.They up graded it (made the rise time faster like on the 7 digital)and checked it out up to 12,500 RPM'S sent it back to me for a $125.00.That way yours will be at least (he claims it to be better)as good as a new 7-AL box,and you can run a 16 volt battery if you want.

This looks like a 20# weight loss vs adding 25# more weight and juggling 65# to the rear.

I want to change it out (even though its worked fine so far), and I am probably going to go with a Dekka intimidator as they are priced right, work well, and they can be had for cheaper under other brand names. I have heard ALOT of bad about optima's new product quality, and after having mine do what it did (thank goodness it was in a box or my trunk would have been a mess) I will never buy on for any application again just my

Everything I ever do to this thing - only adds weight to it. I need to LOSE weight. I think in my case - a lightweight battery would be a better compromise - as long as it retains the same functionality and starting ability. I'm paying attention because the Optimas in both of my trucks are only retaining a 12.0 v charge and I know I'll be replacing them. Again.

If you run two batteries in parallel they will have the same voltage and double the reserve capacity. If you run them in series you get the same reserve at double the voltage. I run a single yellow top on my street/strip car. I have electric water pump, fan, and fuel pump with a GM CS130 alternator(110amps I think). It works great, I don't ever sweat the car starting or not even with using the fan and pump when the car is shut down. I did drag week 1500miles in the heat and never had a problem starting with the timing locked at 34 degrees as well. I am happy with the yellow top. The big downside I see with the 16V stuff is availability if you have a problem. I manage an Interstate Batteries distributor. It doesn't happen often but we sometimes get calls from racers panicked and trying to find a 16V battery and short of selling them two 8 volt golf car batteries there is nothing I have that can make 16V. That phone call is usually followed by about 3 or 4 others from our dealers that are getting phone calls from the same guy haha. If I were to ever run a 16V battery I would make sure I could go back to 12v easy enough to do it between rounds if thats even possible. I would also make sure the tray was a common size so you could take a battery out of your truck or go to wal-mart or whatever to stay in action. Just my .02 68 Barracuda Formula S 340

After talking to the guys in the battery Lab at Chrysler CTG I learned this. The majority of spiral wound gel battery failures are charging related. Being charged over 14.5 volts or not being charged long enough. They told me when following Optima's charging procedure that they were able to "bring back" 90% of the Optima's that were sent to them in a failed state. Also every door car I have ever scaled was either light on right rear or heavy on the left front, think driver weight. weight in the right rear has to help balance the car before adding preload.

PS I am going to have to go back to their site when I have a little more time,they have some good tech articles. Last edited by MRMOPAR622; 12/30/12 09:33 PM.

At least try it for a weekend and have your extra battery with you. Monitor the voltage and see how it acts, if it gets questionable swap the batteries or add it back in. Easy free weight loss right there. 68 Barracuda Formula S 340

Odyssey er40 $310, better, but has 87 min reserve at 28 lb Braille B3121 $179 at Summit 75 min reserve, 21 lbs. This is the way I am going to go. A 25 amp charger is supposed to bring this battery back to full charge in 30 minutes. For what I do, it SHOULD work. If it doesn't, then it goes in my daily driver. 8..603 156 mph best, 2905 lbs 549, indy 572-13, alky

It has no where near 475 cca's. You are better off getting one from a Deka Battery dealer and buying the adapters.

I guess I'll see how well this battery does. I'm cautiously optimistic. Good choice IMO. In your situation, RC and cranking amps ( 641 )are much more important than CCA ( unless you are racing in Alaska) . EMT ( enhanced mat technology ) is the way to go. Fastest 300

I have yet to see an AGM battery in that size with that kind of cold cranking amps. Cold cranking amps is a 0 degree rating, the hotter it gets the better the battery will perform. Hopefully the battery does what you need it to do.

They refuse to let us race anywhere around here if the track temps get below 65�. It will never ever be used to try and crank anything at any temp below 45� to 50� anyway. I just hope it works fine at a heat soaked 200�.
