Hi I have a 2002 Mitsubishi lancer it is currently having charging problems with the battery or the alternator I'm not sure I noticed that it doesn't really have full charge it doesn't sit or exposed to it usually sits around 11.5 and lower so I replaced the battery brand new battery it started losing power even more I replace the alternator it completely killed the car I found out I got a bad alternator so I got the warranty and got a new one it still isn't charging properly and I have now used two separate batteries and I've just been charging them and trying to drive it I don't currently have the money to take it to a mechanic and have them tell me it's the alternator again whatever I go it seems like people say it's the alternator even though I have it replaced twice now not sure what else I could be.
