I purchased on of these batteries on Big-W online for a mid-high price ($77), expensive enough compared to genuine to expect it would have near to rated capacity.
Above is a pic of the battery advertised. The delivered battery was labelled 7Ah.
They say a picture is worth a thousand words:
So, there it is, after three charge discharge cycles to develop full capacity, two measured discharge cycles. It measures <2Ah, <30% of rated capacity.
Full refund claimed, promptly processed by Big-W Online – return label within a few hours.
