Dead battery now wont come on - Motorola Mobility Moto X

double posted, why?
JUMPS OK
AFTER JUMP WORKS AND DRIVING, AND STOP AND KEY OFF
IT WILL NOT CRANK.
did i guess right?
that means ,
check all fuses first. even the alt fuse (large)
1-battery bad? #1 top failure all cars.
2-Charge system bad. (is the charge/ batt warn lamp glowing when running car, bingo.????

3-or phantom drains. (if no crank just after stall then it not this) if drains while sleeping yes.

the tests are easy, a dirt cheap voltmeter
13.3v to 15v running is good charge system.
if 12v and falling not.

if the battery is bad, the charge system can shut down, so, the best practice is to try a know
good battery out of 2nd car, do you have battery to barrow, this is TOP CHOICE< not thinner wallet.

if the good battery fails then the charge system is failing (note I said system and not a part)
or the belt missing or slipping to the alternator.

btw the 4.3L PCM runs the alternator
PCM is engine brain.
btww, same true 2.2l engine.
the regulator is in the PCM.

so is the charge/bat lamp in cluster
on key on, lamp test
the jump start it , it runs
does the charge./batt.lamp go out.
id be all over that lamp, costs nothing to look.

your battery has been disconnected. if your battery is completely dead you wont be able to remove the key from the ignition. check for loose cables or dead battery

Obviously there are no error messages, so it isn't a simple failure.
Several reasons:
1. Dead or damaged battery - look for laptop battery error light or replace battery (borrow a working battery to test)
2. Dead or damaged Power Supply- look for power-on light to confirm operation. Replace PS if dead. (Borrow?)
3. System board failure. No lights/errors messages etc. Place warranty claim.

battery may be dead-it might charge up but wont hold enough power to turn bike over -buy new one

its should still open even with the battery dead all doors should open manually with the battery dead

Why dont any of you ACTUALLY READ THE QUESTION????? He cant get in the car with a dead battery!!! You cant do any of the ignorant things you all posted if you can NOT ENTER the vehicle!

hello
The battery is starting to be dead. one or couple of battery cells gone dead, need replacement. if the battery is giving enough backup time then no need to replace it immediately. let the battery gone dead, sooner or latter, then you can replace or repair it,
good luck

do the headlight work
if yes then your battery is not dead

if headlights do not work then yes your battery may be dead
