The batteries look old and the contacts are oxidised. There is no date of manufacture or expiry date printed on them so impossible to know how many months/years they have been stored in the warehouse. It was very difficult to solder wires to the contacts despite the use of flux. Two of the batteries didn't charge up even after 24 hours and one battery made a hissing sound which I later found to be leaking electrolyte! When I asked for a full refund I was just told "Open a dispute". No apology was given. I will not be buying from this seller again....
