If the engine cranks slowly or makes no noise when you try to start it. If you jump the battery and it starts but won't start again immediately afterwards. If smoke comes from the terminal connections, do not keep trying to start your car, this most-likely is because your battery cells are fusing. If the water under the caps on the battery is low, you will also have problems starting the car, they may need to be brought up to about a half-inch below the top.
At the very first sign of any problems starting the vehicle.
Car batteries are quite complex, and can have a multitude of problems internally. Failing to start up, corroding connections, and clicking noises are various common car battery problems.
my battery is good but having problems with starting
Not a good sign, This could mean that your charging system (alternator) isn't doing its job. If you have problems starting the car due to not enough battery power, then check your battery to see if it is holding the charge. If after a while that you had to boost or jumpstart your battery your car gradually dies then check your alternator to see if it is putting out charge to the battery.
Yep, will not start.
Dead battery, car will not start
Problems starting a car can be due to one of many reasons, including a problem with the car battery.
try checking the battery cables
you can hook a car radio directly to a car battery or even a car battery charger with out problems, I have done it myself, the only thing to remember is that it needs to have 12 volts and the polarity (+ -) needs to be correct.
The "+" sign is used to mark the positive post.
The most common problem from what I can tell is battery failure. This car needs a much stronger battery than a normal car, and they are still working out the technical side of this.
Usually black. Look for a negative sign ( - ) which is a just a hyphen.
