Do not use under any circumstances
This rogue company has gone to unbelievable lengths to refrain from refunding my money or replacing the incorrect battery they sent me. Like many others below, I found that they failed to respond to any emails or on line messages and their 'chat' facility is unavailable no matter what time you try. One giveaway is the fact that you can't pin down the name of the company which seems to be known by three names, Powerguider, Batterysell, and GoldenTech. Now they have even tried to mislead Paypal after I opened up a dispute with Paypal. Batterysell via Paypal advised me that two new parcels were on their way. Progress I thought at first, but why two parcels, one via Yodel and the other via MyHermes? I checked the tracking nos. and found that both deliveries had been completed! I checked with both couriers and both replied that the tracking nos related to different addresses, neither being mine. Luckily I keep copies of everything and I have now escalated the matter with Paypal, who given my, and everyone else's feedback would do well to take this rogue company off their books. UPDATE : Paypal have refunded my payment but I had to return the original battery at my expense. Worth it because I had to prove to Paypal that Golden Tech had accepted the delivery. The whole process from original order to refund took eight weeks and some considerable effort. I reordered the correct battery from Green Cell and it arrived and is fitted and working perfectly. Wish I had used them in the first place especially as the cost was only a few pence difference.
