Either the battery is not fine and has a dead cell, or something is on pulling power from the battery. Any light on or stuck relay will drain the battery overnight.
Maybe there is a short to earth somewhere in the car so the battery is being permanently discharged.
A battery that won't hold a charge has a dead cell and must be replaced. This is assuming there is not something on that is pulling power from the battery.
Depends on the condition of the battery. Most will hold a charge for at least 6 months if they are not connected to anything.
Battery is getting old and will not hold a charge or there is a drain on it. Battery is getting old and will not hold a charge or there is a drain on it.
I assume you mean if it is stored. It depend on the battery and what condition it is in. A good auto battery will hold it's charge for at least 6 months.
Yes, it will hold it's charge for at least 6 months in storage if it is a very good battery to start with.
Batteries charge nothing they hold a charge.
Remove the negative cable over night. If it does not hold a charge, the battery has a dead cell and needs replacing. If it does hold a charge but will not when the negative cable is connected you have something on that is drawing power from the battery. Some light or a relay is stuck.
bad battery
Has the battery been tested, does the alternator on the Durango try to charge?... If the truck runs with the battery but the battery doesn't take or hold a charge, it has to be the battery being bad or extremely bad terminals so that the charge can't reach the battery. Age of the battery doesn't matter, a fairly new one can still go bad.
The battery brand itself doesn't matter. It depends on how much charge the battery can hold. A good way to improve battery life is to charge it only when your phone is down to the last bar . Don't charge it unnecessary.
