Hi All,

I am new to electrical and electronics. Sorry if my questions are not correct or meaningful.
Kindly help me in my queries:

1. How to produce 500 Amps of Direct current(DC) with 12 Voltage. Looking for less cost solution.
Usage: I need it for use in experimenting with aluminium anodising.
2. I have a UPS/ inverter which charges a 12 Volt 100AH battery. Now how to know how much Amps does this UPS gives to charge the battery.
