man i'am i deep trouble, and i need to improvize a car battery, Does
anyone Knows how?

Yep. Take a piece of lamp cord with a plug on the end.

One lead to the negative terminal of the battery.

The other lead to a 100watt light bulb, a 5amp/100v rectifier diode,
to the plus terminal of the battery, in series......

This will charge the battery pretty well . If you are not careful,
it will also shock the hell out of you, but it is simple .

Clue: don't have the battery in your car when you do this....



It ain't rocket surgery, but you gotta understand what you're
doing. MacGiver could blow up a space shuttle with this setup......

Don't forget about diode polarity: The cathode (-) end of the diode goes to
the battery and the anode end (+) goes to the lamp cord!

OOPS!!!!

i meant a 5 amp/ 1000 volt diode.... I guess you figured it
out yourself, but I couldn't let it pass...

This puts around a half amp, average, into the battery.

Paralleling 100 watt light bulbs will increasse it in steps.

Try not to exceed the diode current rating
