Deep Cycle.

A deep cycle battery is meant to be charged and discharged repeatedly. A 'normal' battery will degrade over time and charge cycles. If you can afford it, a 16V battery would be best.

a 16 volt is not a drop in deal, and its expensive. a good optima or hi cranking amp battery will suffice in most cases to run street stocks. It can be charged as necessary or weekly and not have any real
effect on its performance. A lot of the guys even use the cheapies at the auto discount parts places and warranty them out each year. I don't particularly thinks thats ethical but to each his own.(and please lets don't get that discussion going again). I'm sure there are many exceptions to this advise but in 8 years of racing our batteries have never failed because of charging problems but rather lack of being charged during the week

I've noticed that deep cycle batt. are always lower cranking amps. Just wondered if they're enough to start the car several times during the night. Have always run a 900 cca batt. with no problems. Have even run 3 nights without charging before.

the best battery on the market is a

optima group 31a
deep cycle
1125 cranking amps
155 minute reserve
weighs 60#

summit sells it for 189.98
part number ult 9051-160
It started my 14-1 406 all night long with no charger and never went below 12.5 volts.
Im not worried about no alternator any more.

I have run the Optima battery the past couple years with great success. I do not run an alternator and have never had a problem with voltage. I just throw the trickle charger on it every week and she's good as new. I ran a 16 volt deal a couple races before we were told to take it out and really didn't notice a whole lot of difference.

one thought if your looking to add some weight look into a truck battery would take 2-3 nights of racing to run it down. talking 18 wheeler their huge.

i just run a cheap deep cycle battery from wal-mart has never falled me and after racing all night with it i can take it out and put it in my sons go-kart and he will run all week with it then i charge all day sat and ready for another round. yes i did convert my sons battery opperated go-kart to take a car battery. it is better than riding it for an hour and having to wait 3 to ride

Well if you guys are looking to save weight order you a Total Power batt. They are out of cali. and Jim Sharpenstein is the owner 1-806-935-2448 They carry two types i know of one weighs 31lbs and the one we ordered weighs 24 lbs. We have been running an interstate 24 serious with no problem but have heard alot of good things on this batt. and they run 169.00 for the light one. So if you need to save weight its the way to go. Tell him Steve and Will from New Mexico gave you a tip

Red top Optima. Look on ebay, that's where I bought mine new, shipped to my door for $80. Checked out at 12.5 volts out of the box, 12.5 volts 10 months later when I finally got it in the car. Fired up a brand new 383 like it wuz a Honda!

i appreciate the help, but my question was why to run a regular battery over a deep cycle (running without an alternator) or vice versa?

There is really no need for a deep cycle batt. because we dont run or pull out that many amps out of the batt. In a boat for a trolling lotor yes you would want a deep cycle because you will be taking out a bunch and need to charge everytime you use them. If you use a 10 amp charger on a regular batt it will work fine probally as long as a deep cycle because a deep cycle likes to be used alot and then charged. All batt. develop a memory especially deep cycle ones.

the reason for regular over deep cycle is that many deep cycles are not starting batteries,they don't have the cranking amps needed.basically they will put out a smaller amount for a longer time than an automotive battery.They have fewer plates but the plates are larger,the more plates the more instant amperage it can deliver but the less time it can deliver it for.

I run a deep cycle without an alternator. It will save you if you have problems early in the night and donít have a charger on hand. As to them not having starting power you can get over a 1 thousand cranking amps. So that would be plenty of power to start with and they can take some serious abuse. I have one that is five years old that I used with hydraulics and is still going strong (have not charged all winter). I believe a standard battery would have died a long time ago with the hydraulics that we use. Oh and by the way I picked my battery as a bald they call it for $35 bucks. Itís an older battery they sell for cheaper because its been on the self so long.

i have to agree with u there the deep cycle will take a sh*t load of abuse and i had 1 sit in my truck all winter buried under snow and it fired the truck right up with no boost or charge not thats 1 good batterey and that 1 is about 6 years old or so
