An update folks on the outcome. It has been very positive indeed, so a thanks for all the help and advice I received form you guys
On Sunday night after I got the sellers details going through PayPal and finding the auction on eBay. I sent a message through eBay to the seller. I just stated the battery wasn't working which I had bought in March and would wait to until they reply. It was coming up seller in China :?: this confused me because I normally check this and couldn't recall this. I had always believed it was coming from the UK because I wouldn't have bought otherwise, so I presumed I missed that which didn't seem right. Within 1 hr I got a response saying no problem a new one is posted :!: sure enough it arrived on Wed, brand new. It is again at full charge so won't know if it will juice up again until I run it flat.
The seller never asked for the old battery or what made me think it was the battery and not the charger at fault. Also the box shows it came from Portsmouth and not China on the postage. I now remember this is where the last one also came from.
I am just happy to have gotten another battery and hopefully this one is ok.
I never sell on ebay but is this common for some sellers sometimes to list they are from different countries but are not? Or why do that? If not why is it showing this on the old auction? I am remaining positive about the seller but I do wonder why they posted so quickly without any questions back to me because it was £70. I kind of feel they wer almost waiting to hear back from me about the first battery :? Anyway alls good again so far so my figures are crossed with this new battery.
Thanks again for the help.
