    I own a geek vape, aegis and one of the batteries stopped charging. These came extremely fast and was easy to fill everything out. Thank you

    Well, it’s a long story but I’ll try to be brief. The batteries seem to be meeting expectations, the application is in question. I lost power in a cordless dyson vacuum and wasn’t willing to pay >$100 for a replacement battery unit. I decided I would try replacing the batteries themselves but couldn’t find batteries with leads attached that were reasonably available; found only those with long delivery time that would come from S. Korea at a considerably higher price.

    I found battery holde…

    Started learning Arduino and immediately needed a good rechargeable 18650 battery for a weather sensor project. Lot of cheap clones out there – 18650NZ had a great price for Samsung batteries and a smart charger, delivered in a few days.

    High quality stuff, good price, successful project.

    I purchased 10 batteries online elsewhere and none of the batteries would hold a charge. So next I ordered 10 from 18650batteries.nz. They charged up perfectly and work great. Just what I want for my vaping pipes. Thank you 18650nz!

    These batteries helped upgrade the life and actually kind of boosted the signal on my goggles beings it takes a single at a time it’s nice to have two of them for when one runs out…. Love these batteries and this website used these for quite some time they also go and my Aegis Legend and you can’t destroy them… I recommend them to anyone looking for 18 650s for anything
