100ah is the same as 1 amp for 100 hours or 2 amps for 50 hours. ah = ampere hour. You dont rate chargers by ampere hours, you rate them by continuous amps output

The problem with many good modern atx power supplies is that there is an over voltage protection which needs to be disabled too. Using this system will trigger the overvoltage protection circuit in these new power supplies.

I can check AC current before and After the Transformer. But after circuit go through bridge rectifier. How can I check DC current ? Is there a way to mathematically convert AC current to DC current?

Sir, please correct me if I am wrong.. Isn't it means the battery will always adjust its ampere based on total load impedance? Even without that psu. I mean, if a lamp has 6watt burden and voltage input same as battery/12vdc, it will consume 0.5 Amp. If battery has potential energy of 100ah (as you said, but I'm not sure for that small battery), so it will last for 200hours. Pardon me since I don't know much about electrical stuff.
