You either have corroded battery terminals (where cables hook on battery)or a bad alternator ...Autozone willtest for free
you need a new battery yours does not hold its charge for the cranking amps needed or you have a dead cell in it.
Your Jeep probably won't jump start because the battery is not strong enough to hold a charge anymore. You will need to replace the battery. +++ You will need to replace the battery if it won't hold a charge, but given a suitable source vehicle it should still be possible to jump start (NB 'jump' electrically, not tow-start) any car even with a fully flat battery.
The alt will charge it if you can jump it. If it's too dead to jump, you need a battery charger. It may not charge hold a charge if it;s shot though and if not maint free, make sure water level full
You can charge or jump the battery from jump start posts under the hood on the passenger side.You can charge or jump the battery from jump start posts under the hood on the passenger side.
Its likely either the battery connections (terminals) are dirty, or where they connect is...or the battery while showing a charge is bad when on a load. If it starts with a jump from another car...it's the battery.
Bad connection between the cable end and the battery post or a dead cell in the battery. When you jump a battery, the jumper cable is attached to the battery cable, not the battery itself. Clean the post, either top or side and the ends of the cables and try charging again. If it will not take a charge, it is a bad battery.
Either the alternator is not providing a charge to the battery, or the battery has a dead cell and won't hold a charge. There are auto parts stores (AutoZone, Advance, O'Reilly's) that will check batteries and/or alternators free of charge.
Before you try to charge it with a batter charger. take the battery to an autozone or similar to test the batter and see if its still hold a charge. or if you know that the battery is good then jump start it using another car battery with jumper cables. just remember RED to + and Black To -
A jump box will only partially charge the battery. You need a charger to fully charge the battery.
I would assume the battery is completely dead and needs to be replaced, or you jumped it wrong.or its the alternator i think
Battery is dead or the alternator is bad. Have your battery tested at an auto parts store such as pep boys. Chances are your battery will test bad - unable to hold charge.
NO You have to many AMPS from a car, you can jump start it butdon't charge it.
