New batteries for 98 cummins?
my batteries are on the way out, going to replace them with something just not sure what. the current ones i have in there now are Road Runners from Mills Fleet Farm. they seemed to work just fine but lately they havnt been starting very well in these colder temps. I was kind of looking at the optima red tops.
also if i remember right when i bought the truck back in 01, the original batteries were in it then could they possibly be deep cycle batts? my other concern is when i turn the key for the wait to start light my voltage drops to anywhere from 8-9 volts, and once the truck starts my check gauges light is on for about a minute, while my volts are low then volts go to 14 and the check gauges light shuts off.. what do you guys think?? |
Dont be led into thinking that you need some amazing battery to work in these trucks and they're not deep cells either. You just want a couple that have at least 750 CCA. I like to look for 1000 CCA batteries. Although, if you tend to run accessories or lights with the truck off then you may want a marine type battery since those are partially deep cell and will give you some reserve time while retaining most of the CCA's. You can find batteries cheap but the rule of thumb does apply some that you do get what you pay for. But.....if the place you buy them from has a great warranty and you can simply replace them every time they get weak then that has to be your choice. The one main fact though is, if you're replacing batteries then you must replace both of them at the same time with exactly the same battery. No mixing and matching with type or age.:tu:

Optimal red tops are nice...and not much more than the competition. Get what you pay for...

Since I don't sale batteries I guess its ok for me to recommend Interstate Batteries.
Used them for years. Luke |

interstate seem to do good for the company well i work for with well over 200 semi trucks and a dozen roto mills with 3412 v12 cats they have to do alot of work to crank that much motor especially since they run 20-50 oil. ik they are bigger batteries but still same brand

I've ran exide performance and dekka both lasted longer than the 5 yr warranties on them. Do not do not buy the walmart or rural king brand, bot that I have used are junk. I currently want a optima yellow top with 1200 cca if they make one that big

I work at advance auto, so i know about battery warrentys! I was just curious if a guy needed a deepcycle for the wait to start part.

I bought Duralast Gold Batteries from autozone a couple years ago for my truck. At the time they were one of the top rated batteries you could buy, and I think they still are. They've worked great.

the wait to start is just due to the amount of power the grid heater draws. the reason your voltage and check engine light are on is because the grid heater still cycles till your temp gets up there enough. I don't remember where the temp is pulled or what temp is used. I currently run 2 yellow tops and they work great. I ran Dekka's but they vent so bad it made a huge mess. NHRDA had a coupon in their membership package and I got both batteries for $204 shipped to me so if you know anyone that joined but didn't buy batteries now is a good time to ask.

My batteries died in my truck on my pops last week on a cold morning in VA and he was able to jump it at get down to the local interstate battery dealer 2 batteries taxes and all out the door 130 for 2 new batteries... That beats just about every parts store in town from what pop says by around 50 bucks... Just a heads up sorry I don't have any more details about the batteries but I'm deployed and thats all the info I have from pop... Hope this helps you save some money...

The reason you want batteries in top condition in the Cummins is because when the grids do cycle before startup, they draw a tremendous amount of energy. If both girds are running, they can pull up to 180 amps, and over a couple thousand watts. And also, after the engine does start, the grids will continue to cycle pulling more energy than the alternator can sustain so the batteries will be further depleted until the grids stop or you go faster than 17-20 mph. Matter of fact, the colder the outside temps, the longer the grid heater will cycle pre-startup. So one thing to be careful of is if you live in an area that gets around 0* or less then its advised to let the engine run for a decent period after starting so that the charging system has a chance to recoup the battery level otherwise if you do to many engine on/off short trips then the battery level will not have a chance to build back up and eventually fatigue the batteries.:tu: |
grid heater drains my batteries?

I didn't see anyone answer your question about your voltage fluctuation. It is perfectly normal, the fluctuation is caused by the heater grid cycling on and off in cold weather. It draws a good bit of juice from the batteries.

I just bought two new batteries myself yesterday I bought 850 cca ac delco batteries because I'm a gm mechanic and it was just easy to get them from work they have a 4 year warranty on them they were reasonably priced I paid 100 a piece for them optimas don't have a great warranty on them and are also with my discount trough work were 170 bucks a pop and the voltage deal I agree with bowling its normal and if your batteries are weak your gonna notice a higher drop in cold weather
