Dudd battery. First time it charged for 7 hours and ran out quickly. Second charge, it was left to charge overnight and didn't charge at all. In disgust I shoved it in a drawer. 6 months on I've retrieved it again and am pursuing to have the battery replaced before my warranty runs out in November. I purchased it through the ANZ Rewards System where by I redeemed points. I didn't receive a receipt as such, just a reduction of points notice. I like the product but would appreciate help in getting it to work.
