Battery Safety: Vape Traders NZ chooses its suppliers very carefully; we partner with reputable, reliable companies like Samsung, LG, Sony, and Panasonic, and the batteries we sell are the same ones we use ourselves. However, all rechargeable batteries, regardless of where they come from, require responsible usage. Incorrect handling can lead to damaged hardware or serious injury.

Before using any rechargeable battery, make sure you understand the risks and take proper precautions. Never leave charging batteries unattended, and always place the charging device on a stable fire-proof surface. Do not use any battery or battery charger that is damaged in any way, whether that damage is visible or internal. Always transport batteries in a non-conductive container, and ensure that batteries can't come in contact with each other. Dispose of batteries in a safe and responsible manner. Contact your local council to find out what programs are in place to help you dispose of your batteries.

Vape Traders NZ will not be held responsible or liable for any injury, damage, or defect, whether permanent or temporary, that may be caused by the improper use of batteries. It is your responsibility as an adult to understand what you're doing, and to not do silly things.
