An utter scam: Contrary to the website's implication this company are based in The Netherlands NOT New Zealand which perhaps explains why the promised 7-10 day delivery turned into 5 weeks! The battery when it finally arrived the battery didn't work and to obtain replacement or refund they insist that the original be returned (to the Netherlands) first; that's perhaps not unusual, but in this instance, we then discovered that it is illegal as an individual to ship a lithium/li-ion battery. So Battery Upgrade can and in our case did, ship any piece of junk, confident that you can't return it and they get to pocket the money; $90 down the drain.
