Why does my car battery struggle to start?
However you start to reach a point where the battery starts to struggle to start the engine due to low capacity. Sometimes the engine will start immediately, then other times it just talks a little longer to start, but the battery isn’t able to supply the power, then you are in the situation you are in now.
What should I do if my battery won’t start?
If you run into this type of problem a cheap voltmeter can become your best friend. If you have no starting current, check the “open circuit” (ground cable removed) from the battery and the voltage checked at the battery’s terminals. It will almost always be normal. Reconnect the ground cable and re-check the voltage.
Why does my Mazda 2 battery not start?
Expert: indy-tech replied 4 years ago. When this happens the battery is dropping below 10 volts ,even though the battery seems okay to light and radio etc but lacks amperage to turn the starter motor ,this is why you can hear the relays clicking . Now to check this is very easy. all you need is a voltmeter that has min 20 volts .
How to know if your car battery is bad?
As corrosion develops on the ports, the connection consistently grows weaker. There is less metal to metal contact and therefore it becomes harder for power to transfer from the battery to the starter. If you’re having battery problems, check your ports to see if they’re corroded. If they are, you might think about cleaning them.

Why does my battery have intermittent starting difficulty?
If the battery has an intermittent inter-cell connector problem, the voltage will drop to very close to zero yet if the key is released the voltage will mysteriously go to nearly a full charge condition or whatever it was when the ground cable was reattached as mentioned earlier. I hope this is helpful.
