Ann: High Grade Lithium Results Produce Drill Targets in Portugal-DKO.AX, page-63

Yes, maybe, but I would think that quality would then also come into play.
Have you ever bought those Cheap Chinese Batteries from Bunnings or the Dollar Shop? If so, how did that go.???
From my experiences with batteries, I personally would be happy to pay a little extra for a battery that is made outside of China because I would not want cheap substandard quality batteries in my rechargeable item( car, drill, torch etc) as I have already had to throw some expensive rechargeables out, due to battery failure, and guess where those leaky and sub standard Batteries were made???

That's right, China...........
Says it all really.......

Cheers
