Battery Recomendations
 

Ok guys batteries died in car last race of the year, looking to replace in spring. Any recommendations of brand, type? Dual batteries here front/back

Re: Battery Recomendations
 

If you want something fairly lightweight, I've used Braille B3121 batteries (21 lbs.) with good luck. I try to swap batteries every 3-4 yrs.

Re: Battery Recomendations
 

I've used the oddesy batteries with never an issue. Finally replaced it this year only because it was 5 years old. Never let me down.

Re: Battery Recomendations
 

I also have had good luck with the Odyssey batteries. We use two of the 925's.

Optima yellow top any good for drag racing ? I saw one in the Fletch's stocker wagon @ Indy.

Re: Battery Recomendations
 

Optima yellow tops work great since they are a deep cycle battery. However, you also need a charger made for this type of battery. Sears makes one and I think Optima also has one.

Re: Battery Recomendations
 

Optima Red tops is what I use - never let me down.

Re: Battery Recomendations
 

I've run an Optima yellow top for years. One of the best batteries I've tried, albeit somewhat heavy. It may have been wrong, but I always used a standard charger on it. Never had a problem.

Chuck, You have a PM...........

Re: Battery Recomendations
 

Likely referring to a slow charge on 2 amp or similar ?

Re: Battery Recomendations
 

What's the proper way to charge an Optima if not with a standard charger?

Re: Battery Recomendations
 

The key with an Optima battery is the voltage. You don't want the volt. during a charge to exceed 14.5V. You could put 1000 amps thru it and not hurt it, but to high a voltage will. I work for the company that owns Optima. The Optima charger or a Battery tender. I have always used yellow tops in my race car and trailer. I used a Battery Tender 5amp charger. If you charge it over night you will be good to go. If you have an alternator you can race a whole nat. or div. race without touching it. If you use a big sears charger just watch the voltage.

Re: Battery Recomendations
 

Is any charger that is rated for AGM good to use on Optima batteries?

Re: Battery Recomendations
 

I usually slow charged the week before I went to the track. I don't run an alternator, so there was more than one time between rounds when I'd put the thing on kill until I had a fully charged battery. :eek:

Re: Battery Recomendations
 

With the higher end "S" brand charger I've noticed a voltage creep going beyond the normal 13.2-14V up to and over 16V at times with 2 different chargers. If I catch it, unplug the charger and plug it back in it'll stay at less than 14V from then on. I mentioned this situation to a couple of other racers and they found they had same creeping problem. This also happened on lead acid batteries that I was charging over night and the acid was boiling by morning. Now I won't leave a charger running, only a battery tender. Please stay aware!

Re: Battery Recomendations
 

I bought an Optima red top for my gremlin about 6-7 years ago.If I wasn't racing for a few weeks or more I hooked it to a Battery Tender.In the winter it stayed in the car in my trailer hooked to the BT.Eric M.still has it in the car.Keep it trickle charged Eric,it will go for a few more years.

Re: Battery Recomendations
 

Chuck........keep the Honda battery in the front and the regular battery in the rear like it is....better measure those battery boxes before you jump on some of these suggestions.............get the Optima Red Top and forget it.

Re: Battery Recomendations
 

I must be a rare exception, I have had great luck with plain old wet batteries, my favorite being a DieHard., although the Interstate in my Mustang has been working great for 5 years. I just put the battery on a 2 amp charge the night before leaving home, and I`m good for the weekend. Both my cars do have functioning alternators. Ans speaking of DieHards, I installed a new 27 series DieHard under the hood on my F350 in May 1999, and the damn things still in there. Even after being parked outside all winter, in the spring it has always started the engine without a charge, although I can`t imagine it can last too much longer.

BATTERIES
Must remain in stock location and be of sufficient capacity to start
car at any time. Second battery permitted if securely mounted in
trunk. Must be automotive type. Both batteries must be same type,
size, and weight. See General Regulations 8:1.

Re: Battery Recomendations
 

I tried deep cycle marine Die Hard batteries. They would last a year or so. Again this is with no alternator. However when used with an alternator they're hard to beat. All four of my street cars have one. I've had a couple last over 5 years!

Re: Battery Recomendations
 

Thanks everyone for the responses I will have some home work over the winter. See you all in the spring
