It could be the starter in it. It may be weak or need replaced.
have you checked to make sure you have a good clean earth???
Your smoke detector may still be beeping after installing a new battery because there could be dust or debris inside the detector causing a false alarm. Try cleaning the detector with a vacuum or compressed air to see if that resolves the issue.
If you unplug the battery is for sure is not going to start. What are you asking?
Check your battery connections. If they're tight and no corrosion is present, then your battery may be dead. Recharge or jump start the battery. Still clicking? Replace the starter.
starter, solonoid, ignition, battery. if it clicks when you turn the key then the battery is really dead or its the starter the battery could still be jumped if its the battery.
That could be the alternator or the battery. Try jump starting your car with another car's battery. If it still does not start, it is probably the alternator. If it starts, your battery is dead.
Make sure connections are on tight.
the battery job is to start the car so the alternator will kick in after the car is running
Sounds like a dead battery. You need the battery to start the car, but once it is running the engine runs completely off of the alternator (which also recharges the battery if the battery is still good).
check your battery then the connections if it still wont start try changing the starter solenoid if possible
this just happened to us -- after installing new starter, it turned out that the battery connection was not correct -- auto parts store checked and cleaned terminals and fixed connection, all for free. this just happened to us -- after installing new starter, it turned out that the battery connection was not correct -- auto parts store checked and cleaned terminals and fixed connection, all for free.
