Scott C 03-08-2005, 11:38 PM I heard someone talking about a problem with leaking batteries. After I replaced alternator and batteries at 70k, the passenger side battery will start to leak acid within 4 months. I am on my 4th passneger side battery and this is an 02' truck. I have to take batteries to a different NAPA every time so they dont catch on and will still honor my warranty. Is there a tsb on leaky batteries? dmaxalliTech 03-09-2005, 10:23 AM make sure your cables are clean and tight, corroded cables will not get good contact and cause heat at the connection which could lead to leakage. That or try a better battery? partsguy662 03-09-2005, 10:56 AM I heard someone talking about a problem with leaking batteries.

Is there a tsb on leaky batteries?Out of curiousity, what Napa battery number are you using?? Scott C 03-09-2005, 03:06 PM Hey parts guy. If I ever get the truck back from the shop after the 8 injectors I will let you know which battery it is. I know that they are the "nascar" batteries but I'm not sure about the CCA. partsguy662 03-09-2005, 03:16 PM Hey parts guy.

I know that they are the "nascar" batteries but I'm not sure about the CCA.The nascar select batteries have been very good, except for the dual terminal units (8434/78) Those things are garbage..I think I've defected a dozen of them in a year...Actually, I don't even stock them anymore... ockgator 03-14-2005, 09:21 PM At our shop we replace a lot of delcos because of leakage problem, we use interstate and have no leaks.... so far. I put gel battery in my truck, and yes my original delco was leaking, waiting for wife's 03 to start leaking 02Duramax 03-14-2005, 09:42 PM Mine started leaking mad a real mess I had enough of that and bought the interstate Jels alittle costly but there spost to last longer and sure wont leak around 250.00 for two Scott C 03-16-2005, 11:21 AM Mine are the dual post units. That could explain the problem. Does anydody have the optimas? pepperidge 03-16-2005, 08:13 PM optima... If you need the model # let me know ... 02Duramax 03-16-2005, 11:05 PM Accually I posted wrong I have the red top Optima's WNTRYDN 04-06-2005, 04:09 PM Use Optima Batteries!!!!!!!! The Best. You Are Going To Spend About $75.00 On An Acid Battery So Why Not Spend $110.00 And Never Worry About Re-placeing Them Again.. P. S I Had Same Problem Bonesmech 04-27-2005, 09:45 PM Scott C, Are both your batteries a match set. Having two differrent batterys can cause problems. One battery can cause the alt to slightly over charge, and boil the other batt. AYR TIME 04-30-2005, 08:53 PM Thanks for the heads up on the leaking batteries. Where on the battery case are the batteries leaking? Around the posts? Thanks Richard | ||
