Most auto parts stores have a tester specifically intended for that purpose.
Yes. How old is the battery ? . Is it the correct battery for your car/truck Are the battery terminal connections loose or corroded ? Clean ,tighten Get the battery checked at a local garage ( load test )
The average car battery life is 5 years. If a person does not drive their car much, the battery could actually last even longer. Some people claim to have batteries over 7 years old in their car, and the battery test excellent.
Then replace it.
Yes. That's what car battery chargers are for.
'Automotive Battery' is a posh phrase for a 'Car Battery'. On purchasing, they will guranteed for 3 years, or 5 years. If it is known that the battery is older than the guarantee period, then replace it. If you don't know the age of the battery. then #1. check the battary terminals for white sulphonation. This is an indication that it is old and should be replaced. and #2 when trying to start a car and there is no starter motor noise, then the battery has 'collapsed', probably due to old age. NB Car batteries consist of 6 cells. Each cell is composed of lead and copper plates, in a bath sulphuric acid. The sulphuric acid ionises, the hydrogen ions move towards the copper place, and the sulphate ions move to the lead plate, giving the white sulphonation at the terminals. This movement of ions is part of the normal electrical function of the battery. However, with age the sulphate ions form lead sulphate(white), This builds up with age and when the lead sulphate touches the copper plate, then the battery 'collapses'; no electrical powe/electricity. It is 'short circuited'. The hydrogen ions become hydrogen gas and there is the possibility of explosion. NNB When fitting a car battery look for a little hole in the top rim. This is the vent hole to carry away hydrogen gas. You may find a tube/pipe fitment to go in this vent hole, so fit it!!!!!
touch the wires to the battery terminal
Put the red test lead on the positive and the black test lead on the negative post of the battery and see the result.
In my experience this usually does mean that the alternator is not sending the battery enough charge. Many auto parts stores will bench test your alternator for free, some can even test it while it is still on your car. I recommend getting it tested. They can also test your battery; you would be surprised how fast a battery can go bad. Sometimes you can get a battery that is just a lemon. I hope this is helpful.
A car battery warranty can be bought at the place you got your battery from. Plus you can also bring in old battery for core money.
Disconnect negative cable first from old battery and connect it last when installing new battery.
You would make a car battery comparison by comparing which car battery seems better. You shouldn't keep the old car battery near because you can get it mixed up with the newer ones.
Aplly battery voltage to it, it should jump, engage.
