so that the car wont run, hence no significant output from the alternator.

@tri400 There was still gas in the fuel line.He was starting it the first time so it would empty the fuel line and fuel injection. This allowed him to get a reading on the battery during starter use without getting input power from the alternator.

@callmejacko Hi, I am truck certified and the computers on a big rig will drain all three batteries in less than a week when it is parked. The 'Battery Maintainer' (tender) is a good investment. I use a light bulb on my riding mower in the winter to draw off a little energy and recharge it at 1-Amp in the winter as part of normal maintenance to keep the battery working for many years. [This is a good question]

Very good info for DIY people who have no other means of testing the battery. I like the fact you used actual values from Industry Standards and not a marginal opinion.

this is realy realy bad for you car !!!

You can pull the harness to the coil pack or distributor also to prevent the car from turning over during testing as well.

thanks. I have another question regarding car battery chargers. is it good to recharge installed/working car battery regularly with the help of car battery charger as part of maintenance? Or the charger is only for emergency purpose when car wont crank

If you have a battery that is going to be unused for an extended period of time you need a unit called a Battery Tender.
