So my jeep won't start unless it's jumped. Now idk why this is because the battery is only a couple months old and I replaced the alternator about a month ago. The battery is an economic battery, but I don't think that should make it only last a couple of months. Any ideas??

 

any electrial items on xj work like head light good and bright

 

no ya turn the key and nothing

 

battery have it checked ,no current

 

shouldn't it charge up once jumped?? It dosent do that if so

 

alternators on newer cars are not like old cars there mad to just keep the battery charged not from dead try a nother battery if thers one that will hook up

 

1. The ONLY way to accurately determine battery condition is to have it "load tested".Simple test and it's free. Take the battery back to where you bought it for this test. Also, be sure that all connections are SHINY clean.

2. Ensure your charging system is working. If you have a voltage gauge on your dash, it should read between 13.5 and 14.0 volts. If you don't have that gauge, use a meter and measure for that voltage directly at the battery.

 

alright I guess ima take it to autozone tomorrow I hope it's not the battery though cues I'm broke lol I may need to strip the wire leading to the battery and lets some cleaner copper into the terminals

 

Soo I took the batery up to autozone they tested it and it was fine. I was confused so I went back put it in my jeep and it cranked right up. Weird

 

connections .....

 

Yea kinda cleaned up the positive terminal and it started right up
