Would a regular volt meter work just as well? Or is a car battery too much for a volt meter to handle?

This someone can use to load test a battery,usually CTCT CTdoes it to determine battery condtionCTcondtion CTcondtionspecifically charge holdinCTcondtionholdin CTcondtionholding capacity.

It is a load tester; the voltmeter cannot load test the battery.

Some will complain that this only does a 100amp load test and your car's starter motor will draw much more than that. I think it is still useful at identifying a weak battery, but it may pass some that are marginal because they aren't tested under full load.

$7.95 shipping to Montreal ... not bad.

so would you have to fully charge the battery before using this tester?

Yes. There is a voltmeter built into the tester to first verify the charge is within operating limits.

I have run into numerous issues with our cars in the past years where this would of been handy. If it does in fact work, it could potentially save you from buying a new battery when the issue could be something else.

Wrong. You can put a voltmeter in series with any (safe) load and check the current.

If you have a volt meter you can do a load test just by turning everything on. Headlights, radio, heater fan, rear window defroster etc. this is your load. With everything turned on you should have a good indication of your battery condition. Listen to your starter operating (this is your biggest load) if it does not turn the motor over quite as fast as it used to you probably have problem in the making.

Check the water level in your "sealed" battery. The acid evaporates and you need to add "DISTILLED" water. Simple maintenance that will help forestall a problem.

Only if your voltmeter will read AMPS. Most don't and very few are capable of reading more than even a very low load.
Otherwise try if yourself and your voltmeter will be toast.

You could theoretically test your battery with a voltmeter if you had some way to apply a steady load of at least 100A or so for at least 10 seconds - but that is not easy to do without a tester like this. However, you would do so by measuring the voltage across the battery terminals with the load applied. If you try to measure the current by connecting an ammeter in series with any significant load you will either fry your meter or blow a fuse - they are just not built to measure more than about 10A or so.

Then it would be an ammeter.

Voltmeters are by design high resistance devices so as minimize any effect on the circuit being tested.
Ammeters by contrast are low resistance for the same reason.

It seems people are confusing multi-meter, which generally combines voltmeter, ammeter, ohmmeter.
