Element 82 Limited is a retailer of CTEK products, we are not the only one. But we are the most knowledgeable in batteries, charging systems, application use and charging voltages, battery chemistries, and system integration.
If you'd like to visit our showroom to see all the CTEK products in person you can find us at 235G Bush Road, Rosedale, Auckland, New Zealand.
Locals support loyalty. If you purchase a CTEK product your first point of contact is the reseller you purchased from. While the internet is great, it's not on your doorstep like a local store.
We are here to support purchases directly from Element 82, there are multiple distributors within NZ of CTEK, and some use repaired chargers to replace a faulty unit, we don't. But we do require your serial number for support calls which can be found on the bottom of your charger prior to any support being provided.
If you want to purchase from an online store because it's cheaper or they offer free delivery or from TradeMe then realise it's cheaper for a reason and ask yourself what could be missing? If you purchase from an overseas store you will be required to return the unit to them for replacement if faulty or technical assistance. They are also required to provide you with an SDoC when required for electrical safety approval standards.
If you are not sure which product you need prior to purchasing CTEK includes a guide for battery size using AmpHours (Ah) which is normally indicated on your batteries label. Please call us on +64 9 476 4171 to discuss which model is best for you and give us the courtesy of us selling you the product to help pay for our time.
