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.

 

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.

I agree. Interstate batteries are very good.

 

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've been wondering the same thing now that its cold. I've always ran deep cycles and never had any issues, this summer I switch to stand 850 ccas and now anytime that wait to start light comes on, it just drains both batteires very quickly

 

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.
