well its been a while since my cars had a problem so im here for some more help. the old s 13 is acting up again it seems my battery dosent hold a charge but at the same time it seems my alternator dosent charge it after i drive the car around for like 10 minutes. it charges but then stops. well any ideas? i mean it think its logical that i need a new battery which im doing, but any help would be useful if anyone has had this problem

 

always easy to just hit up Advance Auto and get them to run the test
