this year we cant run a alternator nor can we run any battery bigger then 12 volts. So what iam wondering is whats the best battery.
Other then charging it at the track since its such a pain in the behind what can we do ti still maintain 12 volts
Would running a amp guage be a good idea or not so i could tell how low the battery was getting???

i don't run an alternator and i only use a plain old stock 12 volt interstate battery and never had any problems. i try to charge it every week but there were a couple times i didn't and ran two weeks on it and had no problems.

You shouldn't have any problems unless you're running long races. Make sure to get a high quality battery. You tend to get what you pay for with these kind of things.

I've been thinking about running a heavy guage (maybe 10 or 12) "hot" wire from the tow truck to the battery in the stocker...wouldn't this charge up the battery in the race car nwhile on the way to the track?

I think the healthiest thing for your battery would be to put a slow trickle charger on it.

For a 12 volt battery, Optima is the best in my opinion. But we have run ordinary 12 heavy duty batteries with no trouble also.

Industrial truck battery. I charge it up a night or two before the races. Never had a problem. We've gone two weeks between charges w/no issues. Like 29 said, get a good battery.

Heck, we turned it over around Xmas time for kicks and giggles, and it fired right up after sitting cold for 3+ months in the garage w/no charging.

deak-jr is right the large truck battery is the best way to go, they are heavy and much larger than most average batts. but hold a heck of a charge. the optima is a good battery but not much better than any other quality battery, they are WAY overpriced.
but for what your wanting a good truck battery would be the best way to go.
is there a only 1 battery rule? put 3 6 volts togethere. that will be a way around the no battery larger than 12 volts.

A good battery with good reserve capacity should work well for you. Reserve capacity is how long the battery will put out 12 volts at 15 amps(i think thats right) most are around 100-120 minutes or so. So unless you do a lot of cranking and starting ea night or run races more than and hour you shouldnt have any problems. I wouldnt go buy the cheapest thing i could but your average quality name battery should work.

We run a red top Optima because it is a sealed battery and more vibration resistant so you dont have to worry about acid leaking if you roll it. They claim it wont leak even if its broke, luckily we havent tested that yet.


On the other hand if you are in a class that wont allow you add ballast, a big ole battery is an easy way to add weight to the rear of the car.

Another thing that iam wondering about is that HEI takes 13.5 to 14 volts to run at optimum voltqage so am i going to have to re jet it then since i wont have the voltage to carry more spark

I use a group 31 batteries that is commonly used in large trucks boats and use with hydraulics. It is an 800 cranking deep cycle battery that can go for weeks without charging. I do charge over night before a race, trickle. I also take the charger with me to the track just in case something goes wrong and I have to do a lot of cranking. It is a heavy battery and larger then the common one.

We never ran an alt. on our street stock and we never had a problem. We just ran a normal interstate battery and charged it every week. If you run two days in a row try to put the charger on it for a while the second day to give it a bit of a boost. You will be fine without a alt. Good luck!

Somthing I've been thinking about trying is using a jump pack at the track when starting it. Since the biggest draw is during start up, and most packs recharge via cig lighter.

go to a local automotive shop and get a behind the counter battery!

auto zone, o'reilly, advance...all thoese guys have better batteries but they are for business's sales.

if you do buy a counter battery be shure to check the dates...they are aging while sitting on the shelf!

optima red top is for use with a alternator. according to optima themselves useing it without a charging system will shorten its life and effect its ability to re charge fully.

yellows are deep cycles

I run a good, deep cycle battery, usually no alternator, trying one this year on the driveshaft yoke and one on a switch. But any good battery should do you fine.

In my brothers hobby stock we have run the same battery the last two years and it sat in the corner of the garage for for about a year and had been frozen a couple times! We picked up put on the charger for an afternoon and its ran good no problems with it just put the charger to it saturday morning and take it off about and hour before we leave for the track and never had any problems.

If you're really worried about it, take a second battery and swap them out between the heat and the feature. I've swapped out with the one in my pick-up to make the feature.

Eljojo,

That's the setup that is used on campers, a feed wire from the tow vehicle charges the camper battery while it's being towed. Just remember to put a 20 amp self resetting circuit breaker in the feed circuit to the race car. You can get 'em for a few bucks at any RV trailer dealer. When you hook up the feeds with the battery being very discharged, it would try to draw more amps than your feed wire would allow without overheating the wire (unles you run battery cable for the feed wire!!).


We have a popup camper and a travel trailer, and we use this setup on both of 'em. Have been thinking about adding a breakaway switch and small battery on the race car trailer, since it has electric brakes on it too.

We run an optima red battery on a 3/8 mile track.We average about 25 laps per night. The lowest voltage our battery seen last season was 13.43 volts after a caution filled feature. No alternator just put on trickle charge 24 hours before the race. We took voltage readings all season to be sure we didn't run low voltage in the feature without using an altenator. We had no problems with this battery.

Ran my purestock in an enduro at the end of the season with no alt. two hours of racing and two starts and it cranked over just as fast when we started it to load it on the trailer after,(never checked the voltage)
