I have to replace the battery in my 2008 Maxima every year. The last one lasted 6 mths. Any idea what could be draining it.


Put an amp clamp on the battery cable to see if anything is drawing it down while the key is off. It will always draw a small amperage because the computer doesn't shut off.

I keep puting a new battrie in and after it sits for a few days the thig is dead


It sounds like you've got something drawing the battery down when the truck is turned off. Make sure all of the lights in the car are turned off, and nothing is plugged into the cigar lighter (Even a phone charger not plugged into a phone can cause a small draw on the battery). If your door ajar light is staying on with all of the doors closed, the car may be leaving things powered up or lights on thinking the door is open.
If none of these are causing the problem, the next step is something called a parasitic draw test. This involves checking the "load" on the battery with everything turned off using something called an ammeter. With the ammeter hooked up inline with the battery, you can unplug fuses from the panel until the excessive draw goes away. Once you find out the circuit that is drawing the battery, you can start unplugging at different points down the harness to isolate your draw. The draw could be a slight short circuit in a wire or component, or a failed part staying on when it's not supposed to.

If my starter is bad on my 2004 f250 6.0 would it turn slow and i just put new batterys in


maybe. Check the terminals are tight and the cables aren't corroded! These can be known for bad starters and cables, also fuse block corrosion. I would do a starter draw test with an amp clamp on the negative lead to main battery, not auxilliary battery. This will tell you how much amperage your starter is drawing.

Battery is being drained by something, its new


2 things, not enought cold cranking amps, or while you where trying to start the car the brushs inside the starter caused a ark on the armature causing the starter not to be working at 100% option 1 have a drain test done or 2 replace the starter the drain test will show how much amps its taking to spin the starter if its pulling a high amount of amps/votage to spin the start then replace starter

Something is drawing power from the battery constantly


PUT A TEST LIGHT FROM THE GROUND POST OF YOUR BATTERY TO THE GROUND CABLE CLAMP.REMOVE THE CLAMP FROM THE BATTERY AND THE LIGHT WILL LIGHT IF THERE IS A DRAIN.START UNPLUGGING STUFF [START WITH THE ALTERNATOR] AND WHEN YOU GET TO THE DRAW THE LIGHT WILL GO OUT. TRY PULLING FUSES TO NARROW DOWN THE CIRCUT.WHEN THE LIGHT GOES OUT CHECK THE OWNERS MANUAL TO SEE ALL COMPONENTS THAT YOU NEED TO CHECK. MOST OF THE TIME THERE IS A DIODE GONE IN THE ALTERNATER CAUSEING A 4 AMP DRAIN,IT WILL NEED A RECTIFIER PUT IN IT.HOPE THIS HELPS.
