Is it okay to use 12v 4amps battery to have power is garage?

[Adrian_boch]

So I have installed a 12v light in garage which needs power. the 12v light has thin wires and I was wondering can I connect them to the battery with them burning later on the night or something?

I want to get this battery http://www.amazon.co.uk/Lextek-Motorcycle-Battery-Peugeot-Speedfight/dp/B0089CFXE4/ref=sr_1_2?s=automotive&ie=UTF8&qid=1384467624&sr=1-2&keywords=speedfight+battery

I always use thick wires. The thicker the wire the more resistance it has > in amp-age.

What's the wattage rating of the light or the current that it demands?

I think a thick wire has LESS resistance than a thin wire of the same length and material.

The greater the cross section the less the resistance.

I bought twin core wire from a motorhomes converter when i set up a similar system,in fact when it arrived it was no different to the stuff sold @ Wilkinsons by the metre. The wire was substantially thicker than that attached to the light fighting.

May I suggest that you read up on Ohms Law.

1 mm^2 lighting flex is ok up to 10A.
