Mine cost $190 but with a bit of planning you can definitely do it for less than $100.



In the quest for a longer cheap lasting laptop battery.

Looks awesome man :) will definitely by trying this

Spent mine with mates up in Paihia after a 12 hour cruise through Cape Reinga, 90-mile beach and the like.

The harbour fireworks in Russell/Paihia were awesome...but I cruised off early back to my accom after some guy punched me for no reason and I tried getting him back(3 other guys ended up getting him for me ;)) so I was happy to head back before any arrests were made




I have moved across the ditch.  Now residing in Melbourne as a VOIP/Video Technical Trainer/Engineer.
