Batteri-butik.se is a scam site and a sister site to hotbattery.co.uk. I received a battery that just simply didn't work and the site owner / manager, Jiangfeng Yu, replies quickly until I asked for my money back - all went quiet for over a week then.
Luckily I paid via PayPal and so was able to claim a refund via them, however, I do not recommend anyone use batteri-butik.se, or any of its affiliates.
