what could this be. If my car sits for 10 days it wont start. I jump it and it starts and will start eveytime untill the next time I go away..could just be a bad battery?
thanks guys

 

Give a good charge and load test it. Check your connections. My service guys (construction equipment) always want to blame the battery. but more times then not it's the connections.

 

If the battery is allowed to get too low, then it'll be no good. As Muss says, charge it. You might consider a float charger with automatic shut-off, or a "smart charger".

 

My guess would be that the battery is toast or connections as Muss says above. Don't forget to check the ground connection to your body. A battery should hold a charge for 10 days, unless you have a drain somewhere, which is also a possibility.

Hint- Put some info about your car in your sig, it may come in handy for diagnosis at some point.

 

yeah, and if you do get your battery replaced or if it turns out to be ok, then check for a parasitic draw. I'd say anything over 50ma would be a problem, like a stuck relay or a short.

 

First get your voltage measurements (precrank) then get the battery load tested (free). Yes, could be a drain, as mentioned......sounds like it's not the case,..but still VERY good to quantify where the drain amount rests with your car.

Beyond that,..it's matter of alternator/VR health (charging ok? Seen any alt lites?),..any connections in the path should be checked FIRST, as noted by someone....all the way back to the starter area..

Prob. the battery.
