battery tester November 27th, 2008Does anyone have a way to check your battery to see if its dead?? I dont have a battery tester. Im not sure if its my battery, or my altinator??
The car is dead, no lights come on, horn wont blow, alarm wont even come on, its totaly dead…I WANT TO KNOW IF THERES A WAY TO CHECK THE BATTERY!!!!
first of all you should wear goggles to protect your eyes if going further to check and work with a car battery!..
Acid will burn your eyes in no time!..And batteries could explode even while in car and working!…
The easiest way to check is getting those positive and negative post together for a bout 1 second and see if the spark is good enough (I mean a nice strong spark)!..
Or take it to a mechanic shop or preferably to an auto parts store to be checked!…
if taking the alternator also could be checked at the auto store for free!…Auto stores won't charge you to test or re-charge your battery!…neither the alternator check!..
if you don't have any lights then your battery is completly drained!..You should go to an autoshop and recharged it for free and it'll take about 30 minutes!…
Put it back in your car and turn it on, and if you see the "check engine" light or any other "warning" light, then your alternator most probably will be at fault!…

The only way to test any battery is by doing a "load test." This is where a load is placed and the voltage is measured across the terminals.
Unless you have this specialized equipment, you can not do this by yourself. Take it to any automotive places and they will test it for you. Battery dealers and automotive shops are usually good places to start.

ideally you just take a voltmeter (there cheap)
it should read around 12.6 volts if the battery is good.
Have someone try to crank the engine.
a good battery should stay higher than 9 volts

If the car will still start…after its started, take the cables off your battery. If the car still runs..the alternator is still good. Usually a bad alternator will give signs of going, like when you turn on the radio, the lights dim, or if it just seems to be losing power.

Yes. You stick your tongue on the metal cap and if your head blows off, its fine.
