Kauka I got the Duralast yellow top today. Put it in and of course starts just fine which I figured it would, it did last time this happened and I put in a different battery. Now that time the battery was not new, a friend of mine gave took it out of the truck that his son was "grounded foever" from driving That was six months ago. Is the cycle starting again" and six months from now is it going to happen again?

How do I check my system for something grounding out? How do you check for a bad ground if everything is working? I HATE ELECTRICAL PROBLEMS!!! you can end up running around the jeep trying to get that perverbial wire out of your back pocket!

speepdaedeesi hey they best way to check it.. this worked for me

turn on your headlights

if your battery is bad they will dim ALOT or even turn off completely when you go to start it.

this is the ONLY way i knew it was my battery. it would either start fine, or not start at all, with no inbetween, so i thought it was everything else but the battery.

also, save 100 bucks and get a duralast yellow top. works fine for me and its -26 lows here with -36 windchill, 3 yr free replacement, 3 year free jumpstarts?

spend that 100 on something else

speepdaedeesi if you have another vehicle or can work it out, take the battery to autozone and drop it off. they will test it and charge it for free.

mine was doing the same thing. showing between 12-14, but sometimes it wouldnt start and sometimes it would.

my terminals were super tight, and super clean.

if it is the battery, i reccomend duralast.. im not sure if all of them have it, theres black, red, and yellow batteries, but mine came with a 3 year no questions asked warranty. i went with the yellow top. 800 cca because its cold as hell here.

and you dont even need a reciept. if you kill the battery and leave it dead for a month and it completely kills it, take it to the zone, they will test it, if they say its bad they can look up that you bought the battery on the computer and bam. free replacement with a brand spanking new battery.

it also came with a free 3 year 24/hr roadside assistance for jump starts. it starts the day you call the 800 number on teh card, and you have 60 days to call after buying the battery. they will pay for someone to come out to you and jump start you up to twice a year for 3 years free, up to 50 bucks each time.

pretty sweet deal for 90 bucks if you ask me.

the black and red should also come with a warranty. im not sure about the free jumpstart deal though. itll be on a sticker attatched to the battery.

if your military you get 10% off also, so its tax free basically lol

Kauka checked it.. it was clean and tight

Its like the battery don't have any amps. It has voltage but no cranking power.

chesterspl Let me have got me thinking about it now
01-14-2009 08:16 PM
Kauka No I didn't check it this time. I'll go clean and reconnect it.
01-14-2009 08:00 PM
chesterspl You said you cleaned the battery contacts but did you checks the ground wire, not on the battery side but the other side, on the block. If it's gunked up that could be it. Sounds like the battery is receiving charge from the alternator. I have had the same problem on a different vehicle though and the ground was corroded on the block. Hope that helps. Or if you have all ready done it, sorry, that's all I got.

Battery issues?

Ok..I have one for the experts. Got in the jeep yesterday and it wouldn't start. Jumped it started fine. Only issue that is noticeable when running is the voltage meter fluctuates between 12 adn14 volts. This has happened before about six months ago. I thought it was the voltage regulator replaced the alt (built in regulator) but no change. The neg. battery terminal was loose thought that was is as when I tightened it down the fluctuations stop battery charged no problems.

Until now.. its happening all over again. Cleaned and tightened the terminals Put the charger on the battery this morning so I could go to work. When I put the charger on the battery it said the voltage was 12.7 battery at 90% charged. After charging it said 13.4 and 100%, got in turned the key, it cranked for about 3 sec and died.

Any help figureing this out before I spend 180 for a yellow top Optima would be nice..
